Q: Read the following article and answer the question. Article: Our sense of smell, which we normally take for granted, is nowadays being increasingly used for purposes which might surprise us if we realized them. One area in which smells are created to achieve particular results is marketing. For some time producers have taken advantage of our sense of smell with regard to household goods. When pleasant smells are passed through a store's air conditioning system, people tend to spend more time in the store and buy more. For example, the smell of chocolate is used in sweet stores, while the smell of leather and perfume are used in clothes stores. In a test, people looked at the same types of shoes in two rooms--one filled with purified air, the other with a smell of mixed flowers. Eighty-four percent of the people preferred the shoes in the room with the smell of flowers. In fact, many said they would have paid up to US $ 10 more for a pair. Smells also have other uses. Research has shown that certain smells can help to calm anxious people and increase their feeling of safety. Smells such as that of flowers and pine forests might therefore be used to relax patients in doctors' and dentists' waiting rooms, and to make the environment more pleasant and less stressful to _ Some companies are experimenting with different smells to produce different efferent effects on their workers according to the time of day. For example, early in the morning they might put the smell of lemon in the air conditioning system to wake people up. In the middle of the morning, when the atmosphere tends to become more tense, the smell of wood could be used to calm people down. Before lunchtime the smell of melting butter would encourage people to go to lunch on time. After lunch, when people often begin to lose attention, the smell of mint would increase their watchfulness. While some of these uses of smells may e helpful and effective, not everyone would agree with their use to control customers in stores. It has been suggested by consumers' organizations that one way to avoid this new... Question: We can conclude from the text that _ Answer:

Q: Read the following article and answer the question. Article: Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That's nothing more than a fiction. But could we really clone endangered animals? To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope , the Sumatran tiger, the cheetah , and the giant panda. Next, could we really clone extinct animals? In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth , Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother. In reality? Probably not. On the one hand, it's not likely that extinct animals' DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as _ , definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother? Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today's world. Not only do most extinct animals have no habitat to live in, but the other plants and animals they depended on for food may also be gone as well. Question: In the author's opinion, it is possible that _ . Answer:

OPTIONS:
- some extinct species may be cloned, but not survive
- extinct species may be cloned and easily survive
- a gaur can have a monkey as a surrogate mother
- all the extinct species may be cloned

A:
some extinct species may be cloned, but not survive
