Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like. What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important. The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.
6. In order for life to develop, a planet’s orbit must not be

Read the following passage and choose the best answer (A, B, C, D):
Cities develop as a result of functions that they can perform. Some functions result directly from the a great city regardless of the disadvantageous ingenuity of the citizenry, but most functions activity. result from the needs of the local area and of the surrounding hinterland (the region that supplies goods to the city and to which the city furnishes services and other goods). Geographers often make a distinction between the situation and the site of a city. Situation refers to the general position in relation to the surrounding region, whereas site involves in physical characteristics of the specific location. Situation is normally much more important to the continuing prosperity of a city. If a city is well situated in regard to its hinterland, its development is much more likely to continue. Chicago, for example, possesses an almost unparalleled situation: it is located at the southern end of a huge lake that forces East-West transportation lines to be compressed into its vicinity, and at a meeting of significant land and water transport routes. It also overlooks what is one of the world's fiest large farming regions. These factors ensured that Chicago would become characteristics of the available site, such as being prone to floding during thunderstorm Similarly, it can be argued that much of New York City's importance stems from its early and continuing advantage of situation. Philadelphia and Boston both originated at about the same time as New York and shared New York's location at the Western end of one of the world's most important oceanic trade routes, but only New York possesses an easy-access functional connection (the Hudson-Mohawk lowland) to the vast Midwestern hinterland. This account does not alone explain New York's primacy, but it does include several important factors. Among the many aspects of situation that help to explain why some cities grow and others do not, original location on a navigable waterway seems particularly applicable. Of course, such characteristics as slope, drainage, power resources, river crossings, coastal shapes, and other physical characteristics help to determine city location, but such factors are normally more signifiant in early stages of city development than later.
4. According to the passage, a city's situation is more important than its site in regard to the city's .

Will Shortz: Puzzle Maker
When you ask a child what they would like to be when they grow up, common responses might include firefighter, pilot, doctor, or athlete. But those jobs don’t capture the attention of all kids. Take Will Shortz, for example. In eighth grade, at the age of 14, Shortz had to write an essay about what he wanted to do with his life. He wrote about his desire to become a puzzle maker – someone who creates games and puzzles, such as sudoku or crossword puzzles. That same year, he sold his first puzzle to the magazine Venture. By the age of 16, Shortz was regularly contributing puzzles to magazines. In college, Shortz found that there was no traditional way to study puzzles or become a puzzle maker. There were no classes offered on puzzles. Fortunately, after becoming bored with his economics studies, Shortz learned that his university offered a special programme that allowed students to suggest and create unique fields of study. After creating and completing two courses on word and math puzzles, Shortz switched his major to enigmatology – the study of puzzles. Shortz and his professors then created new classes that explored all aspects of puzzle-making. He studied the history, construction, and psychology of puzzles, mostly on his own. Because there were no professors of enigmatology, Shortz realized that he probably was the only student at his university to know more about his field than any of his professors. He did well in school, but upon graduating, Shortz did not know how to get a job creating puzzles. For summer work, he joined the magazine Penny Press, where he realized that he could find work as a puzzle editor. Shortz then found a job creating and editing puzzles for Games magazine. This seemed like a dream job because he could create new kinds of puzzles and be surrounded by great puzzle makers. After 15 years at Games, Shortz accepted a position as the editor of The New York Times’ crossword puzzle. When he first joined, the newspaper’s crossword puzzle was seen as very difficult, and few readers could complete it. Shortz made fundamental changes, such as including everyday language in the clues and answers so that many more people could enjoy it. Today, he credited with making the crossword appealing to a wider audience. Some of Shortz’s most famous puzzles have related to the news for that day, such as the name of the winning president on Election Day, and a love-themed puzzle on Valentine’s Day.
4. Which statement describes Will Shortz’s college experience?

Are Vitamins Beneficial?
If you happen to flip through TV channels, you are likely to come across a commercial for a new vitamin or supplement designed to improve your health. These pills often promise the world, claiming to cure baldness, or kick-start fat loss. But in the medical community, there is some debate as to whether these products provide any tangible benefits at all. Millions of people worldwide begin their day by popping a multi-vitamin. These pills are supposed to effortlessly provide our bodies with vitamins in case we have missed them in our meals. It seemed to be a no-brainer that everyone should take one. Scientific studies, however, have painted another picture. In 2006, a study conducted by the Agency for Healthcare Research and Quality, which used the strictest possible standards, concluded that multi-vitamins have zero effect on reducing a person’s chances of getting cancer or heart disease. The only people multi-vitamins benefitted were those in poverty-stricken nations who suffered from nutritional deficiencies. In 2009, a related study by the Fred Hutchinson Cancer Research Center came to a similar conclusion after monitoring 160,000 women for a period of 10 years. Antioxidants are another supplement that is promoted to improve health and prevent aging. Antioxidants are found in vitamins A, C, and E, and are supposed to greatly reduce cellular damage. However, in a study that involved over 180,000 adults, those who took a combined dosage of these vitamins actually increased their risks of dying by 16 percent. One likely cause for these negative results is that people who eat healthy diets and take vitamins are probably getting too many nutrients, which can be toxic. Then why are these supplements being promoted? Many experts blame the health industry in the US and other nations because supplements are not highly regulated as they should be. What is worse, vitamin makers are not required to list negative side effects like medicines do. In many cases, it can even be difficult for the US’s Federal Drug Agency (FDA) to ban risky ingredients due to lengthy and expensive legal battles. On the other hand, after these studies were made public, people continued buying more vitamins than ever. It seems that no matter what evidence is presented, the majority of people are not ready to give up on a magic pill just yet.
