Question: Read the article and select the best answer. Article: Bigger-brained birds survive better than their feathered friends with smaller brains, according to a study published on Tuesday. Scientists have suspected that birds with large brains in relation to their body size lived longer because they were able to adapt their behavior to environmental challenges. Now they have provided evidence that it does. "We have tested the hypothesis that the brain can buffer animals against the environment and help them to survive when they face environmental challenges," said Daniel Sol of the Centre for Ecological Research and Forestry Applications in Barcelona, Spain. After comparing death rates, brain size and body mass of 236 species of birds from different regions of the world, Sol and scientists in Britain, Hungary and Canada discovered that the bigger the brain the better. Crows and parrots have the largest brains, while pheasants have a relatively small brain. Earlier studies have shown there is a relationship between the size of the brain and an animal's capacity to create new behavior and adapt more easily. "The idea is that if you have a big brain, you are more capable of adjusting behavior and responding to environmental changes. This can help you to survive," said Sol, who reported the finding in the journal Proceedings of the Royal Society B: Biological Sciences. Tamas Szekely of the University of Bath in England and a co-author of the report, said birds were ideal to test the hypothesis because they are the only species in which brain size and behavioral response to environmental challenges such as climate and habitat destruction is understood. Question: Which of the following statements is true? Options: A: Pheasants have the smallest brains of all birds. B: Crows and parrots have the largest brains in all animals. C: A pig's brain is bigger than a cock, so it must be cleverer than the cock. D: The discovery is now only certain about and mainly limited to birds.
Answer: D

Question: Read the article and select the best answer. Article: Handshaking, though a European practise is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other's hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. "Let's shake (hands) on it" sometimes means agreement reached. Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or-her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly- There is generally a misunderstanding among the Chinese that westerners are usually open and straighforward, while the Chinese are rather reserved in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you. Question: According to the text. which of the following statements is true? Options: A: Westerners are more reserved than the Chinese. B: Westerners are unwilling to shake hands. C: We should make a judgment before shaking hands. D: We shouldn't shake hands with European women.
Answer: C

Question: Read the article and select the best answer. Article: During Nelson Mandela's 19 years in the prison on Robben Island, one particular commanding officer, Badenhorst, was the cruelest of them all: "A few days before Badenhorst's leaving the prison, I was called to the main office. General Steyn was visiting the island and wanted to know if we had any complaints. Badenhorst was there as I went through a list of demands. When I had finished, Badenhorst spoke to me directly. He told me he would be leaving the island and added: 'I just want to wish you people good luck'. I do not know if I looked dumbfounded , but I was amazed. He spoke these words like a human being and showed a side of himself we had never seen before. I thanked him for his good wishes and wished him good luck too. I thought about this moment for a long time afterwards. Badenhorst had perhaps been the most cold-blooded and cruelest commanding officer we had had on Robben Island. But that day in the office, he had showed that there was another side to his nature, a side that had been hidden but still existed. It was obvious that all men, even the most seemingly cold-blooded, have a heart of kindness and that, if their hearts are touched, they are able to change. Actually, Badenhorst was not evil; his inhumanity had been encouraged by an inhuman system. He behaved cruelly because he was rewarded for cruel behavior." Question: How did Mandela feel at what Badenhorst said? Options: A: Awkward. B: Surprised. C: Angry. D: Upset.
