Question: Read the article and select the best answer. Article: What's your opinion on spicy food? Some people cannot handle even the smallest amount of chili in their dinner while others can't get enough of it. Scientists have long been puzzled by why some people love chili and others _ it. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chili is related to childhood experiences, and cultural influences affect our taste buds, too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported. "We have always assumed that liking drives intake---we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits with intake of chili peppers," said Professor John Hayes from Pennsylvania State University, who led the study. But before you look at the study, you should first know that "spicy" is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrill, something they usually get from watching action movies or riding a roller coaster. In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personality, for example. Whether they like new experiences or tend to avoid risks. They were then given cups of water with capsaicin , the plant chemical that makes chili burn, mixed into them. By comparing the answers to questionnaires and what participants said they felt about the spicy water. Researchers found that those who most tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water. Interestingly, we used to believe that the reason some people can withstand spicy food is that their tongue have become less sensitive to it. However, this latest study has found otherwise. It's not that... Question: What's the main idea of the passage? Options: A: What he or she likes to eat mainly decides on his or her personality. B: That a person enjoys spicy food depends largely on the personality. C: His or her childhood experiences decide on his or her personality. D: His or her cultural background decides on his or her personality.
Answer: B

Question: Read the article and select the best answer. Article: Sweet peas, cucumbers, grapes ---- what do you think they have in common? None of these vegetables grow on trees. They all don't have strong roots, big trunks or long branches, which makes it harder for them to get sunlight. But don't worry. They have developed their own unique way of growing taller climbing! Take sweet peas as an example. The plant grows as a straight stem until it finds something to hold onto, either a nearby tree or a stick. That is when the stem makes small coil that helps the plant hold the stick tightly. How these plants are able to do this has been a mystery to scientists for years. Even Charles Darwin was interested in this question. But it is not until now that a Harvard research team has finally found the answer. The study was published in the Journal Science earlier this month. The key, as it turns out, is inside a kind of thread-like cell called "g-fiber cell", which has the ability to shrink or stretch. Each stem of the pea plant is made of several layers of g-fibers. Once the plant finds something to hold onto, cells on side of the stem start to shrink, forcing the whole thing to bend and coil, which is a bit like how our muscles get our bodies to move. What's more, a pea's coil is not exactly like that of a spring. If you look closely, you may find that a spring coils all in the same direction, but a plant's coil is in two opposite directions, like a telephone line. This means that the stem can stay soft when pulled gently but become strong enough when pulled harder. "You want the plant to have a little bit of flexibility so that if the wind blows or an animal disturb it, it doesn't break," explained Sharon Gerbode, author of the study. "This structure allows the plant to easily accommodate small movement, but then if something really serious happens it can become strong and protect itself." Question: According to the article, which one is true about "a sweet pea's coil"? Options: A: to be like that of a spring B: to bend all in the same direction C: to make the stem hard break D: to make the stem get soft when pulled hard
Answer: C
