[Q]: Article: It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400,000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

[Q]: Article: By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat? To solve the problem, we should have to double our food production. We can also develop a diet of algae , insects and meat grown in laboratories. Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars. Man-made meat looks like meat, feels like meat and it is meat, although it's never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land. China has developed "green super rice", a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years. Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein , low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes.
Question: In order to exist in the future, people have to _ .
Options: (A) move to other planets (B) produce rain in laboratories (C) build new laboratories for food research (D) increase the food production or look for other food sources
[A]: D

[Q]: Article: Barbara Morgan's lifelong dream has always been to travel into space. On August 8,2007,her wish came true. The former teacher was one of seven crew members on the Space Shuttle Endeavour, which flew into space from NASA's Kennedy Space Station in Florida. Morgan taught at a primary school in Boise from 19751998--with some time off for astronaut training. In 1985, she was chosen as a _ for Christa McAuliffe, who was to be the first teacher in space. On January 28,1986,the Space Shuttle Challenger exploded just 73 seconds after takeoff killing McAuliffe and the other six crewmembers. After the Challenger accident,Morgan continued to teach. In 1998, she was asked to become an astronaut. Morgan's mission aboard Endeavour includes overseeing the move of 5000 pounds of goods from the shuttle to the International Space Station and operating the shuttle's robotic arm. Morgan gave students an unusual class after she was in space. Morgan's outofthisworld class was broadcast live on NASA television. Her husband Clay Morgan said he couldn't help but smile as he watched her talk to students. "I'm just so proud of her and how she's going to do all this and do the work of an astronaut as well as a teacher," he said. "She just kept telling me how unbelievable it was to be in space and I think it's much better than she expected." One student asked Morgan how being a teacher compared to being an astronaut. "We explore, we discover and we share," she said. "The great thing about being a teacher is you get to do that with students, and the great thing about being an astronaut is you get to do it in space, these are both wonderful jobs." The 25minute questionandanswer meeting also included the astronauts entertaining students by swallowing floating juice bubbles and playing with Pingpong balls.
