Question: Read the following article and answer the question. Article: Most of us would like to have glowing skin, especially as we get older. The good news is that you don't have to wait until summer to catch some sun rays. Scientists have found eating plenty of fruit and vegetables is by far the best way to achieve a healthy, golden glow. Dr. Ian Stephen said, "Most people think that the best way to improve their skin color is to get a suntan . But our research shows that eating lots of fruit and vegetables is actually more effective." The team first assessed the skin color of people in relation to their diet. Those who ate more fruit and vegetables a day were found to have a more golden, yellow skin color. Those with a healthy glow had a higher presence of carotenoids , which play a role in the immune system. Carotenoids are commonly found in fruit and vegetables such an yellow and red peppers, spinach, apricots and melons. The team then studied the relation between skin tone and attractiveness. They used specialist software to operate the skin color on the images of 51 faces to simulate more or less carotenoids and suntans. Participants were then asked to adjust the skin color to make the faces look as healthy as possible. Given the choice between skin color enhanced by suntans and skin color enhanced by carotenoids, people preferred the carotenoids skin color. The study shows that not only do people use skin color to judge how healthy other individuals are, but they are accurate when they make those judgments. While this study focus on Caucasian faces, it suggests this phenomenon may exist across cultures, since similar preferences for skin yellowness are found in an African population. Question: What's the author's intention of writing this passage? Answer:
OPTIONS:
- To show us how to get glowing skin.
- To persuade us to get suntans every day.
- To explain different diets in different cultures.
- To share his experience of improving the skin.
Answer: To show us how to get glowing skin.

Question: Read the following article and answer the question. Article: Customs are social habits. They have been handed down through generations among groups, social classes, etc. Customs can be described as ways of doing things. They are particularly strong in social practices on the occasions of births, marriages and deaths. In China, these days, some people in cities are learning from Western customs. For example, some brides dress in the long white dress that is usual bridal wear in many Western countries. Every people has special customs for New Year. The Han people have many interesting Spring Festival customs. And now, quite a number of people living in the cities have followed the Western customs of sending New Year greeting cards for January 1st. One interesting custom in China is that mothers wrap up their babies tightly .This is not the custom in Western countries, where babies are usually dressed in loose garments. Question: The difference about clothing between Chinese and Western babies is that_. Answer:
OPTIONS:
- Chinese babies are usually dressed in new clothes
- Chinese mothers are used to dressing their babies in colourful clothes
- Western babies are dressed in bigger clothes while Chinese babies are usually wrapped
- Western babies have more clothes than Chinese babies
Answer: Western babies are dressed in bigger clothes while Chinese babies are usually wrapped

Question: Read the following article and answer the question. Article: A new genius in physics like Einstein will emerge , scientists say. But it may take a long time .After, more than 200 yeas separated Einstein from his nearest rival , Isaac Newton. Many physicists say the next Einstein hasn't been yet, or is a baby now. And researchers say there are many factors working against another Einstein emerging anytime soon. For one thing, physics is a much different field today. In Einstein's day, there were only a few thousand physicists worldwide, and the theoreticians who could intellectually rival Einstein probably would fit into a streetcar with seats to spare. Education is different, too. One essential aspect of Einstein's training that is overlooked is the years of philosophy he read as a teenager--Kant, Schopenhauer and Spinoza, among others, It taught him how to think independently and abstractly about space and time. Einstein was also an accomplished musician. The interplay between music and math is well known. Einstein would furiously play his violin as a way to think through a knotty physics problem. Today, universities have produced millions of physicists. There aren't many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills to more practical and rewarding efforts. "Maybe there is an Einstein out there today," said Columbia University physicist Brian Greene, "but it would be a lot harder for him to be heard." Especially considering what Einstein was promoting. "The actual structure of space and time bending? My God, what an idea!" Greene said at a recent gathering at the Aspen Institute. "It takes a certain type of person who will knock his head against the wall because you believe you'll find the solution." Perhaps the best examples are the five scientific papers Einstein wrote in his "miracle year" of 1905. These" thought experiments" were pages of calculations signed and submitted to the prestigious journal Annalen der Physik by an unknown.What might happen to such a submission today? "We all get... Question: The writer mentioned Newton in the text to _ . Answer:
OPTIONS:
- show other scientists are no equal to Einstein except Newton
- explain the difficulty to find a talented physicist
- praise his scientific contribution to the world
- explain why there won't be a new Einstein soon
Answer:
explain why there won't be a new Einstein soon
