Your brain will grow and you’ll have improved self-control and_______ skills

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
Ever since humans have inhabited the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier, communication is accomplished through sign language in which motions stand for letters, words, and ideas. Tourists, the deaf, and the mute have had to resort to this form of expression. Many of these symbols of whole words are very picturesque and exact and can be used internationally, spelling, however, cannot.
Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally. A wink can be a way of flirting or indicating that the party is only joking. A nod signifies approval, while shaking the head indicates a negative reaction.
Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warm, and instruct people. While verbalization is most common form of language, other systems and techniques also express human thoughts and feelings.

Which form other than oral speech would be the most commonly used among blind people?

Read the following passage and choose the best answer (A, B, C, D):
Where humans have planted crops for food, unless they are organic, poisonous chemicals have been sprayed on them; insecticides are used to kill insect pests and herbicides are used to kill weeds. Fungicides fight off fungal diseases. Artificial fertilizers are added to the soil to increase the yield of the crops. If these chemicals are used in excess, some of them dissolve in rainwater and drain into rivers, streams and ponds, polluting the water and killing the wildlife. The “weeds” competing with the farmers’ crops include wild flowers and many of these have become endangered through the use of herbicides. Insects rely on plants for food and breeding sites so the number of these are affected by a reduction in the number of plants. Many birds depend on insects for food so the numbers of birds may be affected by the use of both insecticides and herbicides. One of the reasons why the Barn Owl is endangered is due to a shortage of insects and it may also be poisoned by eating insects affected by chemical sprays. The case of DDT and other chemicals known as organo-chlorines is well known. These were first used extensively in the 1950s, sprayed onto crops to kill insect pests. Unfortunately, after a few years, it was noticed that birds of prey were rapidly declining in numbers and thousands of seed-eating birds were dying. By the 1960s, the once common sparrow hawk was a rare bird in Britain. The sparrow hawk’s prey was the seed-eating birds which were carrying the poisonous insecticides in their bodies. Consequently, many sparrow hawks and other birds of prey were being indirectly poisoned by the chemical sprays. The organo-chlorines also caused many birds to lay thin shelled eggs, which cracked easily. Research showed that the chemicals were entering the food chains and being stored in the fat of the animals’ bodies. For example, a thrush may eat snails which have eaten a sprayed cabbage plant. The thrush may not have eaten enough poison to be actually killed but a sparrowhawk eating several thrushes accumulates so much of the poison that it is killed. The chemicals become more concentrated as they travel up the food chain. Even most humans still have small amounts of organo-chlorines in their fatty tissues although these chemicals had been withdrawn from use by 1976. They are still used, however, in some Third World countries. By the 1980s, the sparrowhawk population had recovered dramatically and it is once again a common bird. This example shows just how dangerous the use of chemicals in the environment can be. As mentioned earlier, some plants are endangered through collectors such as the Venus fly-trap and some tropical orchids, but most threatened plants have become so through the destruction of their habitat. Once very common plants have almost disappeared because of the way humans have changed the land. For example, the Egyptian Papyrus, a type of reed, had been used for thousands of years for all sorts of things such as paper, medicine, boats, baskets, food etc. Then, when changes in the irrigation methods on the river Nile were introduced, this valuable plant almost completely disappeared. It was thought to be extinct until 1968 when a few plants were found in an undisturbed waterway. Orchids have been also collected from rainforests to become household favourites, causing many species to become endangered.  
2. The word “yield” in the first paragraph is closest in meaning to __________

Read the following passage and choose the best answer (A, B, C, D):
Facebook users spend an average of more than 15 hours a month on the social  networking site. While there are plenty who caution against such intensive use — and there are a number of studies detailing the harm Facebook could potentially cause — there also are lots of reports extolling the site’s virtues. As the social media giant prepares for its upcoming initial public offering, here are some ways Facebook just might be good for you.  Spending time on Facebook can help people relax, slow down their heart rate and decrease stress levels, according to researchers from the Massachusetts Institute of Technology and the University of Milan. In a study published earlier this year, researchers studied 30 students and found that a natural high was sparked when they were on the social media network that led to the relaxed heart rates and lower levels of stress and tension. In the study, the students were monitored in three situations: looking at panoramic landscapes, performing complicated mathematical equations and using Facebook. While the first situation was the most relaxing to students and the math problems were the most stressful, the time on Facebook uncovered high levels of attractiveness and arousal. The findings support the researchers’ hypothesis that Facebook’s success, as well as that of other social media networks, correlates to the specific positive mental and physical state users experience.  While many may argue that social media networks only distract employees, research shows the opposite may be true. Research from Keas.com found that a 10-minute Facebook break makes employees happier, healthier and more productive. The study examined workers in three groups: one that was allowed no breaks, one that was allowed to do anything but use the Internet and one that was allowed 10 minutes to use the Internet and Facebook. The Facebook group was found to be 16 percent more productive than the group that was not allowed to use the Internet and nearly 40 percent more productive than the group that was allowed no breaks. “Short and unobtrusive breaks, such as a quick surf on the Internet, enables the mind to rest itself, leading to a higher net total concentration for a day’s work, and as a result, increased productivity,” said Brent Coker of the department of management and marketing at the University of Melbourne in Australia.  Facebook is also in the business of matchmaking. Research shows that nearly 60 percent of singles will friend someone new on Facebook after meeting them in person. If they like what they see, 25 percent are likely to contact their new love interest via Facebook. Once the courting is over, nearly 40 percent of those social networking adults will update their relationship status on Facebook, with just 24 percent telling their friends first. Facebook use between couples will continue through the dating process, the research shows. Throughout the day, 79 percent of couples said they send partners Facebook messages or chat on the social network. In addition, more than 60 percent would post romantic messages on their significant other’s Facebook wall. When the relationship ends, more than half of those surveyed immediately update their status to single, which automatically sends out a notification to their friend list to start the dating cycle over again

Read the following passage and choose the best answer (A, B, C, D):
Some of the senses that we and other terrestrial mammals take for granted are either reduced or absent in cetaceans or fail to function well in water. For example, it appears from their brain structure that toothed species are unable to smell. Baleen species, on the other hand, appear to have some related brain structures but it is not known whether these are functional. It has been speculated that, as the blowholes evolved and migrated to the top of the head, the neural pathways serving sense of smell may have been nearly all sacrificed. Similarly, although at least some cetaceans have taste buds, the nerves serving these have degenerated or are rudimentary. The sense of touch has sometimes been described as weak too, but this view is probably mistaken. Trainers of captive dolphins and small whales often remark on their animals’ responsiveness to being touched or rubbed, and both captive and free ranging cetacean individuals of all species (particularly adults and calves, or members of the same subgroup) appear to make frequent contact. This contact may help to maintain order within a group, and stroking or touching are part of the courtship ritual in most species. The area around the blowhole is also particularly sensitive and captive animals often object strongly to being touched there  The sense of vision is developed to different degrees in different species. Baleen species studied at close quarters underwater – specifically a grey whale calf in captivity for a year, and free-ranging right whales and humpback whales studied and filmed off Argentina and Hawaii – have obviously tracked objects with vision underwater, and they can apparently see moderately well both in water and in air. However, the position of the eyes so restricts the field of vision in baleen whales that they probably do not have stereoscopic vision. On the other hand, the position of the eyes in most dolphins and porpoises suggests that they have stereoscopic vision forward and downward. Eye position in freshwater dolphins, which often swim on their side or upside down while feeding, suggests that what vision they have is stereoscopic forward and upward. By comparison, the bottlenose dolphin has an extremely keen vision in water. Judging from the way it watches and tracks airborne flying fish, it can apparently see fairly well through the air–water interface as well. And although preliminary experimental evidence suggests that their in-air vision is poor, the accuracy with which dolphins leap high to take small fish out of a trainer’s hand provides anecdotal evidence to the contrary.  
3. The word “rudimentary” in paragraph 1 could be best replaced by ____________

Read the following passage and choose the best answer (A, B, C, D):
The British are particular about timings and being late is frowned upon, but being on  time is a complicated matter because in some situations, being a few minutes early on others means being exactly on time and in some instances, it is completely acceptable to arrive 10 minutes to a few hours later than the stated time. This can be a minefield for someone who is new to the UK, so here are some basics rules that will help you get your timings right whatever the situation.  In formal meetings, such as job interviews, you should arrive at least five minutes before your meeting. This will give you time to compose yourself before your big meeting. In the UK, arriving late for a formal meeting is seen as unprofessional and will reflect badly on you. If you are running late, ring your host to let them know you will be late. On arrival, apologize sincerely and offer a reason for your lateness, such as you got lost or the train was delayed. It will help you redeem yourself. However, if you are late because you set off later than you should have, it’s wise to keep that to yourself! With appointments such as visits to the doctor or dentist, the time you are given for your appointment isn’t necessarily the time you will be seen. It is not uncommon you may have to wait between 15-30 minutes before you are seen by a doctor and that can be much longer if it is a hospital appointment. Nevertheless, you should arrive at least five minutes before your appointment and it is recommended you take a drink and something to read.  When you start a new job, you are given your typical working hours. For example, if you are expected to start at 9am, it is not acceptable to arrive after this time. Most employers make an exception if you are late once in a while. If you have an appointment, you need to seek permission from your employer to arrive later on that day. Being late consistently will land you in trouble and you can be sacked from your job if after three warnings you are still late.  There is an unsaid rule that you can be a few minutes late for a lecture or seminar once in a while. When you are late, you should enter quietly and find a seat at the back of the room. At the end of lecture or seminar, you should offer your apology to the lecturer. If you have been invited to a dinner party, you should arrive exactly on time as the host will have planned when they will serve the food. You will find that your host will serve their guests a pre-dinner drink, so that gives you a bit of wiggle room, but if you are running later than 10 minutes, you should ring your host and let them know how late you might be. That way they can decide whether to go ahead and serve the other guests. When you arrive you should offer the host and the other guests your apology for being late.

The field of 3-D printing comes with a new set of legal questions hospitals using the  technology will need to consider, said Bruce Kline, a technology licensing manager who oversees patents for new technology developed at Mayo Clinic. For starters, he said the STL file printers use are a lot like MP3 music files, in that they can be protected under copyright and require licensing to use. Copyright violations can occur if a purchased STL anatomical model file for rare disease is illegally shared with another institution that did not purchase the file from the vendor that created the file.  Under the law, if a device has a functional use it falls under patent law. If it is not functional, it falls under copyright law. Kline said most medical 3-D printing for educational models and complex anatomy evaluation currently falls under copyright. But, he said that will rapidly change in the coming years as customizable 3-D printable medical devices see wider use.  Additive manufacturing (AM) allows the creation of patient-specific devices at the point of care. Kline said an interesting fact is that these devices are FDA 510(k)-exempt if produced by a hospital instead of a medical device vendor. He said this blurs the lines between traditional vendor relationships, since the hospital can now become the manufacturer. However, if a hospital makes a device, it also becomes liable for it. He advised that it might be better for a commercial vendor to make the device for the hospital so the vendor assumes the liability of the device. Custom-made medical devices are also exempt under FDA regulations, Kline said. So, if a physician creates or modifies a device to meet the clinical needs of a specific patient’s anatomy, he said it is acceptable to use under current FDA rules. This may leave the door wide open for use of 3-D printed devices that are customized for each patient using their own 3-D imaging datasets.  It is possible printable device files may become available in the next few years to customize and print on demand. However, Kline said it will be much more difficult to enforce patents on these types of devices. He explained if someone makes one or two devices, there is no economical way for the creator of those device files to go after the user/maker of of unlicensed copies of the device to claim lost profits.
2. The word “enforce” in paragraph 4 is closest in meaning to _______

Read the following passage and choose the best answer (A, B, C, D):
Despite the fact that humans haven’t returned to the Moon since the cancellation of the Apollo program in 1972, there have nonetheless been incredible advances in space exploration in recent years. All across the world, human time is the most valuable commodity – particularly when it comes to solving problems. Far from stealing jobs, the majority of advances in artificial intelligence and machine learning are designed to automate relatively “simple” processes and free up time for humans to do what they do best. Already we have had a taste of what AI can achieve from space, even as far back as the early 2000s with the launch of the Earth Observing-1 (EO-1) satellite, which helps analyse and inform the appropriate response in the event of a disaster, such as hurricanes and volcanic eruptions. In some cases, the systems in place on EO-1 began capturing satellite images of disaster zones before ground personnel were even aware that a disaster had occurred. More recently, AI has been used on the Mars Curiosity rover, where AEGIS software is able to identify intriguing rock or soil patches that should be targeted for analysis. This significantly expedites the process of collecting data from the surface of Mars as the robot isn’t relying solely on human commands. Richard Branson’s Virgin Galactic – which hopes to soon begin conducting commercial flights – charges between $200,000 to $250,000 per ticket for a flight where passengers will experience just several minutes of weightlessness beyond the Karman line where space officially begins. Therefore, previous space missions have always needed to consider very carefully which astronauts they send to space, with the ultimate decision often coming down to an astronaut’s ability to act as a ‘jack-of-all-trade’. In future, it should be possible to automate the computing and engineering tasks that historically astronauts have had to train for. This would mean sending individuals with specialised expertise in science and research in place of the all-rounder astronauts of yesteryear. For success in space exploration in the years to come, we will need to continue along the exponential curve of open source uptake and see advances in the approach to how spacecraft software, hardware and infrastructure is developed and deployed. With this baseline in place, advances in AI-driven scientific research have the potential to propel us forwards.
1. Which best serves as the title for the passage?

Biofuels and the Environment

Leading investors have joined the growing chorus of concern about governments and companies rushing into producing biofuels as a solution for global warming, saying that many involved in the sector could be jeopardizing future profits if they do not consider the long-term impact of what they are doing carefully.

It is essential to build sustainability criteria into the supply chain of any green fuel project in order to ensure that there is no adverse effect on the surrounding environment and social structures. The report produced by the investors expresses concern that many companies may not be fully aware of the potential pitfalls in the biofuel sector.

Production of corn and soya beans has increased dramatically in the last years as an eco-friendly alternative to fossil fuels but environmental and human rights campaigners are worried that this will lead to destruction of rain forests. Food prices could also go up as there is increased competition for crops as both foodstuffs and sources of fuel. Last week, the UN warned that biofuels could have dangerous side effects and said that steps need to be taken to make sure that land converted to grow biofuels does not damage the environment or cause civil unrest. There is already great concern about palm oil, which is used in many foods in addition to being an important biofuel, as rain forests are being cleared in some countries and people driven from their homes to create palm oil plantations.

An analyst and author of the investors' report say that biofuels are not a cure for climate change but they can play their part as long as governments and companies manage the social and environmental impacts thoroughly. There should also be greater measures taken to increase efficiency and to reduce demand.

Biofuel producers ____ know about the possible problems.

Read the following passage and choose the best answer (A, B, C, D):
Herb Hamrol, 103, is among a handful of survivors of the 1906 San Francisco earthquake. Today marks the 100th anniversary of San Francisco’s great earthquake and fire. As the local newspaper Contra Costa Times observes, San Francisco has been “struggling with the difference between commemoration and celebration” leading up to the centennial. The city’s mayor, Gavin Newsom, has acknowledged that the 1906 earthquake was an “awkward” event to mark. Perhaps curiously, along with various exhibitions and lectures, more than one attempt has been made to capture the spirit of the anniversary in dance. The Walnut Creek Diablo Ballet company has produced “Earthquake”, which its creators stress is not just about death and falling buildings, but also the rebuilding of the city. Earlier this month, the San Francisco Ballet held a one-off solo dance performance to the beat of seismic data broadcast live from the Hayward fault. The information triggered sounds such as thunder claps and crashing waves while principal dancer Muriel Maffre improvised. It was “well conceived and beautiful”, the San Francisco Chronicle reported, although not quite as “leading edge” as claimed. At one stage there was a “haunted-house cacophony of screams and clinking chains and running water”, the paper’s critic said. There is a small, dwindling group of survivors from the quake, many of whom were just babies when it struck. A group of five of them - the oldest is 108 - recently met in San Francisco and happily gave interviews to journalists. They will attend a special commemoration breakfast today. One survivor, Della Bacchini, 101, who was one year old in 1906, told the San Francisco Examiner that it was important for the city’s residents to keep the history of the quake alive. "San Franciscans have a lot of guts," she said. “We’ve gone through earthquakes and fires, and the people have stuck together. Certainly, the city’s regeneration after 1906 was remarkable, with three-quarters of the lost buildings replaced within three years. A reinvented San Francisco was unveiled in 1915 with its Panama-Pacific International Exposition. In a commemorative lecture, Kenneth Starr, professor of history at the University of California, compared the compulsion to rebuild in 1906 with the plans to rebuild New Orleans after last year’s disaster: “Once they’re dreamed, once they’ve been there … they never disappear.

Seniors in China are still highly likely to believe rumors and pseudoscience, according to reports. In recent years, China has seen more scientists and science communicators using digital platforms to combat pseudoscience, which is classified as rumors, statements, beliefs, ideas or practices that are stated as fact, but are often fabricated and scientifically untested. Despite that, many young Chinese have experienced difficulties when trying to pass on that message to older people. For example, last year, Dingxiang Doctor, a digital platform that debunks medical rumors online, released 101 articles that disproved common, inaccurate claims. However, many netizens said that when they forwarded the articles to family chat groups, they were questioned, scolded and even removed from the group by older family members. An online survey last year by Tencent, one of China’s biggest online businesses, indicated that nearly 40 percent of middle-aged and senior people had experienced online fraud, mostly related to healthcare products. Yun Wuxin, a food engineering expert who has popularized food science for more than 10 years, believes that, in general, members of the older generation lacked training in logical or critical thinking when they were young, so they have an exaggerated belief in personal experience, tradition or superstition. He said young people, especially today’s younger generation, have received better training and tend to hold skeptical or critical attitudes toward convention. He added that new media that popularize science in fresh, innovative ways － such as short videos, video blogs and animations － are very effective with young people. However, traditional methods, including television, community visits by scientists, neighborhood exhibitions and science columns in newspapers, are very important for middle-aged and elderly people who really need to understand science

A new method for analyzing DNA collected from waterways which can help identify endangered bird species has been developed with the help of researchers from The University of Western Australia. The DNA analysis method developed also with researchers from Charles Darwin University and the Northern Territory’s Department of Environment and Natural Resources provides a new way of understanding the distribution of endangered birds by analyzing DNA collected in the waterways where they drink. The research, which will be published in Endangered Species Research Journal, offers new possibilities to support conservation efforts and increase understanding of birds that are scarce and otherwise hard to capture data on. The team developed a probe to locate DNA in water samples of the critically endangered Gouldian Finch (Erythrura gouldiae), a rainbowcolored grassfinch endemic to the savanna woodlands of northern Australia. UWA Professor Simon Jarman from the School of Biological Sciences said the researchers thought it would be hard to detect bird DNA in tropical conditions where the rate of DNA breakdown was high. “We were also sampling from pools where the water was not flowing and there was a lot of sediment and algal and bacterial growth,” Professor Jarman said. “However we were really pleased to get reliable bird detections from our methods showing DNA can be used to detect many species from the poles to the equator.” Professor Jarman said the Gouldian Finch was a beautiful and iconic species that was endangered due to habitat loss from being hunted extensively. "The DNA method will help to map where the finches are currently found with great accuracy, which will help persuade people to conserve the areas where they live," he said.

“Where is the university?” is a question many visitors to Cambridge ask, but no one can give them a clear answer, for there is no wall to be found around the university. The university is the city. You can find the classroom buildings, libraries, museums and offices of the university all over the city. And most of its members are the students and teachers or professors of the thirty- one colleges. Cambridge is already a developing town long before the first students and teachers arrived 800 years ago. It grew up by the river Granta, as the Cam was once called. A bridge was built over the river as early as 875.
In the fourteenth and fifteenth centuries, more and more land was used for college buildings. The town grew faster in the nineteenth century after the opening of the railway in 1845. Cambridge became a city in 1951 and now it has the population of over 100000. Many young students want to study at Cambridge. Thousands of people from all over the world come to visit the university town. It has become a famous place all around the world.
