Q: Read the following article and answer the question. Article: The language used by scientists to explain complex ideas can be difficult and sometimes even boring. The language, with its Latin words and long scientific terms, could be one reason some people avoid learning about science, especially children. American Danielle Dixson is a marine biologist. She wants to make science fun for children. Dixson has turned that idea into a series of children's books. The nine books are written so that her research is easy to understand. "I just don't really think kids should be left out of it and I thought that story books may be one of the easiest ways to sort of captivate them and have them understand." Danielle Dixson is an assistant professor at the University of Delaware. Dixson says another goal of her science writing is to help increase understanding of the ocean environment. She spent almost two years in the South Pacific working on her post-doctoral research. She went to the island nation of Fiji to investigate coral reefs that are collapsing or, as she says, degrading. The goal of her research is to identify why some healthy coral reefs are breaking down. She also wants to find out how this degradation affects fish that live in and around the reefs. "A number of the reefs are converting from being, you know, these beautiful coral reef systems that have a lot of holes for animals to hide in, into reefs that the coral's degrading and collapsing and then there is not as much hiding spaces for fishes and things like that." Early in her research, Dixson made some videos for people in Fiji. The videos explained her work to the local community. She says she wanted them to understand how her research would help them. For the local children, Dixson started making books explaining her work. This helped to keep them from walking through her "laboratory" - baby pools filled with water she was using for her experiments. "I was living, actually, in the village with some of the locals. It was a lot easier to get research done if they understood what I was doing and how it would help... Question: What may be the title of the passage? Answer:

OPTIONS:
- You Reap What You Sow
- Unity Is Strength
- Haste Makes Waste
- Circumstances Alter Cases

A: You Reap What You Sow

Q: Read the following article and answer the question. Article: Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain in protective hormones , U.S.researchers reported on Thursday. Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer's .University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans."Our research shows that the hormones of pregnancy are protecting the brain, including estrogen , which we know has many neuroprotective effects," Kinsley said. "It's rat data but humans are mammals just like these animals are mammals," he added in a telephone interview."They go through pregnancy and hormonal changes." Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer's and other forms of age-related brain decline. "When people think about pregnancy, they think about what happens to babies and the mother from the neck down," said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida. "They do not realize that hormones are washing on the brain.If you look at female animals that have never gone through pregnancy, they act differently toward young.But if she goes through pregnancy, she will sacrifice her life for her infant--that is a great change in her behavior that showed in genetic alterations to the brain." Question: How do scientists know "Motherhood may make women smarter"? Answer:

OPTIONS:
- Some researchers have told them.
- Many women say so.
- They know it by experimenting on rats.
- They know it through their own experience.

A: They know it by experimenting on rats.

Q: Read the following article and answer the question. Article: There is a forgotten player in the global efforts to limit C02 emissions:the consumer. Households consume one--third of the final energy used in the European Union and produce around two--thirds of city waste.Moreover,food,housing,and private transport account for almost 80%of environmental pressures.So consumers can make a real difference when it comes to fighting climate change. Several factors can direct consumers towards more environmentally--friendly behavior. To achieve this,we need clear and simple information to guide consumption decisions. Indeed.Two thirds of consumers find it difficult to understand which products are better for the environment when shopping. With 58% of Europeans believing that many companies pretend to be green in order to charge higher prices, industry has a long way to go in helping consumers feet confident when making green choices.They should give consumers more information about the carbon footprint of their products,and promote more sustainable behavior among their customers. To be sure, companies are increasingly creating product labels that help consumers make responsible choices--for instance, reminding users of products made from materials that are recycled,renewable, and/or less carbon--intensive. Even so,only,20% of Europeans believe that companies are doing enough to promote environmentally friendly options. In times of crisis, consumers prefer high-quality products that will last long and won't go out of style.Durable products might sometimes cost more, but they don't need to be replaced as frequently. In this way,companies that create durable or recyclable products enable consumers to think differently about their purchases, which can help users behave more responsibly, and thus may help end our "throw-way" culture. However, it is not enough to inform consumers of the environmental features of products. We also need to provide consumers with guidance to establish a practical lifestyle model to follow. This cannot be brought about by regulations alone, but by... Question: The author is trying to inform the readers in the third passage that _ . Answer:

OPTIONS:
- most European consumers lack confidence in making responsible choices
- companies can make a higher profit by making less carbon-intensive products
- people are buying sustainable products to have a lighter carbon footprint
- companies have done enough to allow consumers to make greener choices

A:
most European consumers lack confidence in making responsible choices
