*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Tulou, the special residential architecture of Fujian Province was included on the UNESCO's World Heritage List during the 32ndsession of the World Heritage Committee in Quebec, Canada. In the fourth century, Han Chinese living in the Central Plains area began to migrate south, gradually gathering in Fujian and forming the Hakka communities. As a defence against enemies, the Hakkas chose to live in compact communities, and the tulou was their preferred houses. Tens of thousands of such earthen structures were constructed in Fujian Province. Most tulous are to be found in the valleys, surrounded by high mountains, and some are in the depths of the great mountains. Most are three to four stories high, and look like circular blockhouses . Rooms on the first floor are used as kitchens, rooms on the second floor are used as barns , and rooms on the third and fourth floors are for bedrooms and living rooms. For defensive purposes, the rooms on the first floor have no windows. Raw materials for the tulou were obtained locally. Their main building material was a mixture of clay, sand, lime and water, and egg whites, brown sugar and rice water were added as adhesive agents . It was then mixed to form the walls. Once they dried, the walls were so hard that driving a nail into them would have been difficult. Fir branches, which are extremely strong and do not rot, were used to strengthen them, and many centuries later they have remained their original look. Tulous are located in a region where earthquakes happen frequently, and their circular construction helps them resist the regular shocks. The proven design even inspired one famous Peruvian architect, who paid several visits to Yongding, to build a tulou back home. Not long after, an earthquake struck only 10 kilometers away, and while all the houses around the earthen building fell down, his tulou remained. Question: From the passage , we know that Tulou _ . Options: A: is a special residential architecture of Han Chinese in Fujian even today B: was once the place where the Hakkas chose to live together C: stands in the valleys and is also modern people's preferred houses D: looks like circular blockhouses but easy to fall down in the earthquake

I'm taking a test and have to guess the right answer to the question after the article. Article: American researchers found females are the more talkative sex because of a special "language protein " in the brain. The study, conducted by neuroscientists and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day - over 13,000 more than men. "This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals," said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends. They separated four-day-old rats from their mothers and then counted the number of times they cried out in the "ultrasonic range", the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother's cage, she _ her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less "talkative". The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans. "Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,"... Question: Which of the following can be the best title for the passage ? Options: A: Tests on humans and rats B: Why women are the talkative sex C: Sex differences in Foxp2 protein D: Foxp2 protein determines oral ability

I'm taking a test and have to guess the right answer to the question after the article. Article: No one knows how man learned to make words. Perhaps he began by making sounds like those made by animals. Perhaps he grunted like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him--water splashing, bees humming, a stone falling to the ground. Somehow he learned to make words. As the centuries went by, he made more and more new words. This is what we mean by language. People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. Each contains four or five hundred thousand words. But we do not need all these. Only a few thousand words are used in everyday life. The words you know are called your vocabulary . You should try to make your vocabulary larger. Read as many books as you can. There are plenty of books written in easy language. Your dictionary is your most useful book. Question: In which sentence can the word "contain(s)" be put so that it is a right one? Options: A: I _ several dictionaries. B: Sea water _ salt. C: A dog _ four legs. D: Mr Smith _ glasses on his nose.
