Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name “snakebots.”
But how can such a robot shape be made? A snakebot is built like a chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the “head” of the snake makes all of the modules in a snakebot work together. The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot.
Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars.
With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.
Which of the following best paraphrases the underlined sentence
"Snakebot modules can also carry different kinds of tools, as well as cameras”?

Read the following passage about endangered languages and mark the letter A, B, Cor D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
Ada Lovelace, born in London in 1815, is widely recognized as the world's first computer programmer. Despite the limited opportunities for women in science and mathematics during her time, Lovelace's intelligence and passion for math set her apart. Her mother, Anne Isabella Milbanke, encouraged her mathematical studies from a young age, in contrast to her father, the famous poet Lord Byron.
Lovelace's most significant contribution came from her collaboration with Charles Babbage, the inventor of an early mechanical computer called the Analytical Engine. In 1843, she translated an article about the machine written by an Italian engineer.
However, it was her own detailed notes added to the translation that made history. These notes, which were longer than the original article, included what is now considered the first algorithm designed to be executed by a machine. This made Lovelace the first person to recognize that computers could follow instructions to perform tasks beyond simple calculations.
What truly set Lovelace apart was her visionary thinking. While Babbage saw the Analytical Engine as a tool for calculations, Lovelace believed it could be used for much more. She imagined that computers could be programmed to create music, art, and more, long before the development of modern computers. Her forward- thinking ideas laid the foundation for the field of computer science and continue to influence technology today.
What is the best paraphrase for the sentence: "It was her own detailed notes added to the translation that made history"?

EDUCATION IN THE FUTURE
Education is another area of social life in which information technology is changing the way we communicate. Today's college students may not simply sit in a lecture or a library to learn about their field. Through their computers and the wonders of virtual reality they can participate in lifelike simulated experiences. Consider the following scenario of the future of education made possible through developments in information technology. For children over the age of 10, daily attendance at schools is not compulsory. Some of the older children attend school only once or twice weekly to get tutorial support or instruction from a teacher. For the most part, pupils are encouraged to work online from home. Students must complete a minimum number of study hours per year; however, they may make up these hours by studying at home at times that suit their family schedule. They can log on early or late in the day and even join live classes in other countries. In order to ensure that each student is learning adequately, computer software will automatically monitor the number of hours a week each student studies on-line as well as that students' learning materials and assessment activities. Reports will be available for parents and teachers. The software can then identify the best learning activities and condition for each individual student and generate similar activities. It can also identify areas of weak achievement and produce special programs adjusted to the students' needs.
Children over 10 years old must attend school every day.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions
[I] A newborn baby can see, hear and feel. By the age of five, a child can talk, ride a bike and invent imaginary friends. How does this development happen? [II]We don't understand the way language, thinking and planning develop very well. [III]Now scientists are using new technology to ‘see’ into children's brains. And they are discovering new information about the way a baby's brain develops. [IV]
A study in 2010 showed that children who were afforded more focus often gained an edge in IQ. The brain of a newborn infant contains nearly a hundred billion neurons. This number is comparable to that of an adult's brain. As they mature, an infant assimilates information through the sensory modalities of sight, hearing, smell, taste, and touch. This information fosters intricate connections between different regions of the brain. By the age of three, there are approximately a hundred trillion synaptic connections.
One experiment looked at images of babies' brains while they were listening to different sounds. The sounds were in different sequences. For example, one sequence was mu-ba-ba. This is the pattern ‘A-B-B’. Another sequence was mu-ba-ge. This is the pattern ‘A-B-C’. The images showed that the part of the brain responsible for speech was more active during ‘A-B-B’ patterns. This shows that babies can tell the difference between different patterns. This experiment is interesting because sequences of words are important to grammar and meaning. Compare two sentences with the same words in a different order: ‘John killed the bear’ is very different from ‘The bear killed John.’ So babies are starting to learn grammatical rules from the beginning of life.
Researchers also know that babies need to hear a lot of language in order to understand grammar rules. But there is a big difference between listening to television, audiobooks or the internet, and interacting with people. One study compared two groups of nine-month-old American babies. One group watched videos of Mandarin Chinese sounds. In the other group, people spoke the same sounds to the babies. The test results showed that the second group could recognize different sounds, however, the first group learned nothing. The scientist, Patricia Kuhl, said this result was very surprising. It suggests that social experience is essential to successful brain development in babies.

DEPENDENCE ON TECHNOLOGY: TIME FOR CHANGE!
[I] Los Angeles dancer, Brian Perez, was eating out with his friends one evening when suddenly everyone went quiet. [II] To his horror, he saw that the reason for this was that people were checking their phones. [III] What if they all put their gadgets in a pile in the middle of the table until they had finished the meal? [IV] If anyone picked up their phone, that person would have to pay the whole bill. And so, it is said, the game of 'phone stacking' was born.
The necessity for action like this highlights a major problem in today's society: our inability to disconnect from technology.
But while Brian's idea deals with the obsession in a social context, measures also need to be taken at home. Some people drop their smartphones into a box the moment they arrive home, which gives them the chance to interact with the people they live with. The fact that the phone cannot be heard - it is on silent - nor seen - the flashing lights are hidden by the box - means that they are no longer tempted to use it.
A less drastic solution is to ban electronic devices at certain times of day when the whole family is likely to be together, for example at meal times. This can be hard for everyone, from teenagers desperate to text friends to parents unable to switch off from work. On a normal day, however, dinner takes less than an hour, and the benefits of exchanging opinions and anecdotes with the rest of the family certainly makes up for the time spent offline.
Taking a break from technology is one thing, but knowing when to turn off a device is another. Time seems to stand still in the virtual world, and before you know it, you find that it is three o'clock in the morning. This is where a digital curfew comes in handy, a set time when all devices must be put away. Evenings without technology are usually nice and peaceful and make a more agreeable end to the day. And then it's time for bed. One of the best ways of ensuring you can sleep at night is to ban electronic devices altogether from the bedroom. Lying next to a machine bursting with information is far from relaxing, and the sounds it emits during the night can easily wake you up. With technology out of the room, a line has been drawn between daytime and sleep time, which enables us to switch off ourselves and drift off to sleep.
According to paragraph 1, Brian Perez was shocked to find that_______.
