Question: Read the following article and answer the question. Article: Tu Youyou has become the first Chinese woman to win a Nobel Prize, for her work in helping to create an anti-malaria medicine. The 84-year-old's route to the honour has been anything but traditional. In China, she is being called the "three nos" winner: no medical degree, no doctorate, and she's never worked overseas. In 1967, malaria, a then deadly disease, spread by mosquitoes was _ Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit "Mission 523 "was formed to find a cure for the illness. Two years later, Tu Youyou was instructed to become the new head of "Mission 523". "Mission523" read ancient books carefully for a long time to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, more than 240,000 compounds around the world had already been tested, without any success. Finally, the team found a brief reference to one substance, sweet wormwood , which had been used to treat malaria in China around 400 AD. The team took out one active compound in wormwood, and then tested it. But nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she changed the drug recipe one final time, heating the compound without allowing it to reach boiling point. After the drug showed promising results in mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. " In any case, Tu Youyou is consistently praised for her drive and passion. One former colleague. Lianda Li, says Ms Tu is "unsociable and quite straightforward", adding that "if she disagrees with something, she will say it." Another colleague, Fuming Liao, who has worked with Tu Youyou for more than 40 years, describes her as a "tough and stubborn woman". Stubborn enough to spend decades piecing together ancient texts, she applies them to modern scientific practices. The result has saved millions of lives. Question: Tu Youyou can be best described as a _ person. Answer:
OPTIONS:
- devoted and stubborn
- straightforward and mean
- considerate and tough
- sociable and generous
Answer: devoted and stubborn

Question: Read the following article and answer the question. Article: Directions : Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B, C and D. Choose the one that fits best according to the information given in the passage When top engineers in Germany wanted to build a more energy-efficient car, they headed to the natural history museum to study dolphins and sharks. But it was the boxfish that interested them. "We were surprised when this clumsy-looking fish became our model for designing an aerodynamic car",says Thomas Weber. He is the research and development chief for the car company Daimler. An aerodynamic design reduces wind drag and increases fuel efficiency. The boxfish may look clumsy, but it can start, stop ,back up and zigzag through the water with ease. And it does all this using surprisingly little energy. Daimler's bionic car is modeled on the fish's boxy skeletal system. Like the fish, the car is fast and drives easily. It's efficient too. The science behind nature-inspired inventions is called biomimicry . Biologist Janine Benyus came up with the term. As co-founder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature's best ideas. This month ,the Nature's 100 Best List will be revealed at the World Conservation Congress in Barcelona ,Spain. Benyus co-authored the list of nature inspired designs with economist Gunter Pauli. In Zimbabwe ,a country in southern Africa ,engineers designed energy-efficient buildings modeled on termite mounds . The buildings use vents to keep the air flowing and the temperature cool. A company in Atlanta ,US ,developed a self-cleaning paint modeled on the lotus leaf. When the paint dries ,it becomes bumpy ,just like the lotus leaf. Rain drops form on the bumps and roll off ,carrying dirt along with them. Nature has done billions of years of research. Only the best-designed products have survived. Companies owe Mother Nature a debt for all that... Question: Why did top engineers in Germany go to the natural history museum? Answer:
OPTIONS:
- They wanted to pay a visit to the animals there because they were so lovely.
- They wanted to carry out a research of boxfish and dolphins.
- They wanted to search for a model to base on for building a more-efficient car.
- They wanted to study the science of survival.
Answer: They wanted to search for a model to base on for building a more-efficient car.

Question: Read the following article and answer the question. Article: Commencement is a time for idealism. But economic reality is cruel everywhere; especially for new graduate. They have been told repeatedly that a college degree is an open sesame to the global economy. But that's not necessarily so, according to new research by two economists at he Massachusetts Institute of Technology, Frank Levy and Peter Temin. It is true that people with college degrees make more money than people without degrees. The gap has narrowed somewhat in recent years, which is disturbing. But the earning power of college graduates still far outpaces that of less-educated workers. The bad news, though, is that a college degree does not ensure a bigger share of the economics pie for many graduates. In recent decades Mr. Levy and Mr. Temin show, only college-educated women have seen their income grow in line with economy wide gains in productivity. The earnings of male college graduates have failed to keep pace with productivity gains. Instead, a huge share of productivity growth, which expands the nation's income, is going to Americans on the top of the income scale. In 2005, the latest year with available data, the top of 1 percent of Americans---whose average annual income was $ 1.1 million--- took in 21.8 percent of the nation's income, their largest share since 1929. Administration officials, and other politicians and economists, often, believe that income inequality, reflects an education gap. But Mr. Levy and Mr. Temin show that in the case of men, the average bachelor's degree is not enough to catch the rising tide of the global economy. They argue that the real reason that inequality is worsening is the lack of strong policies that broadly distribute economic gains. In the past, for example, a more progressive income tax and unions promote equality. Positive measures have been _ and new ones have not yet emerged, making the income gap even greater. Mr. Levy and Mr. Temin conclude that only a new government policy can restore general prosperity. That's a challenge to the nation's leader... Question: The passage is mainly about that _ . Answer:
OPTIONS:
- there is a big income gap between female and male college graduates in America.
- college graduates find it hard to find an ideal job after graduation in America.
- research shows that American government should take measures to ensure income equality for college graduates
- college degrees are losing value in America.
Answer:
research shows that American government should take measures to ensure income equality for college graduates
