I'm taking a test and have to guess the right answer to the question after the article. Article: One of India's top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students' performance, making them lonely and even suicidal. Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. "Now, a student doesn't even know who lives two doors away from him because he is so busy on the Internet," said Prakash Gopalan, dean of student affairs. "The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion." IIT-Mumbai, with about 5,000 students, is one of seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming. Starting Monday, Internet access will be banned between 11 p.m. and 12.30 p.m. at IIT-Mumbai's 13 boarding buildings to encourage students to sleep early and to try and force them out of their "shells", Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. "Now they will say we need to listen to a lullaby to go to sleep," said Rajiv, an electronics student. Question: What measure has been taken in IIT- Mumbai? Options: A: Students have unlimited free Internet access in their dormitories. B: Students are forbidden to surf the Internet. C: Internet access is unavailable in deep night. D: Students must go to bed before 11 p.m.

I'm taking a test and have to guess the right answer to the question after the article. Article: Four decades ago a group of college students visited the mountains of Borneo to examine moth populations. Now a team of British scientists, including a member of the original trip, has returned to the same sites to repeat the survey. They have found that, due to rising temperatures, the insects now live 68 meters higher. Global warming is forcing tropical species uphill to escape the rising temperatures at a rate of nearly 2 meters a year, the new study from Borneo suggests. Since this was the only chance to repeat the original survey, the scientist did everything they could to do it exactly the same way, going at the same time of year, in July and August, using photographs to find the exact original sites of the moth traps. "While this is the first study of insects, a few other studies of tropical species are starting to appear," said Thomas. "If you look across all those studies, you'll find the same results, and it's extremely difficult to think of any other explanation for them." While some species might survive by finding places on the mountains with temperatures similar to those of their original habitats, others may run out of habitat on the rocky peaks, warns the study. In a paper in the journal Naturein 2004, Thomas and 13 other experts analyzed the habitats of 1,100 species on five continents, and estimated that on average one quarter were at risk of extinction. Last year a paper published in the Public Library of Science in the US warned that the risk of extinction in the tropics was becoming more and more serious. The authors, Jana and Steven Vamosi, estimated that 20-45% of tropical species were at risk of extinction. Question: We can learn from the passage that _ . Options: A: this survey of moths has been carried out many times B: some scientists have put forward other explanations for the results C: scientists tried to repeat the original survey D: 20-45% of tropical species were estimated to be at risk of extinction in 2004

I'm taking a test and have to guess the right answer to the question after the article. Article: Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots. Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants . Plants make antioxidant to protect themselves from the sun's ultraviolet(UV) light. Ultraviolet light causes chemicals called free radicals to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals. Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body's built-in defences can only go so far without extra help. The key to fighting free radicals with fruits and vegetables is to mix and match colors. It's like sunscreen for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brain's function in rats suggests that these chemicals may help our own brains work more efficiently. Don't just blame the sun. Ultraviolet light isn't the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust , or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food. Question: Which of the following can not cause free radicals to form? Options: A: Colorful food B: UV light from the sun C: Polluted air D: The body itself
