Question: Article: Two thieves came to a house to steal something. They dug a hole in the wall of the house. There lived many mice in the house. The woman in the house saw a mouse crawl into the house in the moonlight. "Look! In comes one," she said to the man in the house. The thief was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, "She found me when I was just in." But the thief outside didn't believe him, so he said, "Let us try to crawl into the house together." At that time two mice happened to crawl into the house, too. The woman saw the mice and shouted, "In come two, catch them!" The two thieves were terribly frightened. The man in the house said, "You saw them come in but where are they? I will catch them tonight." The two thieves started running away at once. The two thieves wanted to make it clear whether they had been found or not the night before. The next day they acted as men selling sweet potatoes and came before the house. The man and the woman were ploughing in their fields. The rope broke and the woman came home for a rope. She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn't wait for her any longer in the fields and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said, "How they look like the two of last night." The man said, "I asked you to fetch a rope, why don't you hurry for it?" The two thieves ran away very quickly without their sweet potatoes.

Question: Article: A couple who held hands at breakfast every morning even after 70 years of marriage have died 15 hours apart. Helen Felumlee, died at 92 on April 12. Her husband, 91-year-old Kenneth Felumlee, died the next morning. The couple's eight children say the two had been inseparable since meeting as teenagers, once sharing the bottom of a bunk bed on a ferry rather than sleeping on night apart. They remained deeply in love until the very end, even eating breakfast together while holding hands, said their daughter, Linda Cody. "We knew when one went, the other was going to go," she said. According to Cody, about 12 hours after Helen died, Kenneth looked at his children and said, "Mon's dead." He quickly began to fade, surrounded by 24 of his closest family members and friends when he died the next morning. "He was ready," Cody said, "He just didn't want to leave her here by herself." Son Dick said his parents died of old age, surrounded by family. The pair had known each other for several years when they eloped in Newport across the Ohio River from Cincinnati, on Feb. 20, 1994. At two days shy of his 21stbirthday, Kenneth-who went by Kenny-was too young to marry in Ohio. "He couldn't wait.' son Jim said. Kenneth worked as a railroad car inspector and mechanic before becoming a mail carrier for the Post Office. He was active in the church as a Sunday teacher. Helen stayed at home, not only cooking and cleaning for her own family but also for other families in need in the area. She taught Sunday school, too, but was known more for her greeting card ministry, sending cards for birthdays, sympathy and the holidays to everyone in her community, each with a personal note inside. "She kept Hallmark in business," daughter-in-law Debbie joked. When Kenneth retired in 1983 and the children began to leave the house, the Felumlees began to explore their love of travel, visiting almost all 50 states by bus. "He didn't want to fly anywhere because you couldn't see anything as you were going," Jim said. Although both experienced declining health in recent years, Cody said, each tried to stay strong for the other. "That's what kept them going," she said.
Question: From what Cody said, we can learn the children _ .
Options: (A) were not in front of their father (B) don't look after their father (C) foresaw their father would go (D) surrounded their father

Answer: C

Question: Article: We might think we know which colours do what.The idea that red wakes us up or blue calms us down is deeply rooted in Western culture.But do they really change our behaviour in the ways that we assume? When it comes to scientific research, the results are mixed and at times contested.Some studies have found that people do better on cognitive tasks when faced with red rather than blue or green; others show the opposite.The idea is that if you repeatedly have a particular experience surrounded by a certain colour, then you eventually begin to associate that colour with the way you were feeling or behaving.A school career spent reading your teacher's red writing circling your mistakes forever makes you link red with danger.Blue meanwhile is more likely to be associated with calmer situations like marvelling at a big blue expanse of sky. Of course there will always be exceptions --- the comment from the teacher saying "well done" is also written in red.It is true that people do make different associations with different colours, but whether this translates into behaving in a certain way or succeeding at a particular task is a different question. In 2009 researchers tried to clarify the situation.They sat their participants at computer screens colored blue, red or "neutral" and tested them on various tasks.With a red screen people did better on tasks requiring attention to detail, but when the screen was blue they did better on creative tasks.In practice this might be tricky.In a classroom you might want to think creatively some of the time and pay attention to detail at others. However, when another team tried to repeat the study with a larger group of people in 2014, the effect of color disappeared.The initial study consisted of just 69 people.In this new, bigger study, of 263 volunteers, background color made no difference. So colors might well have an effect, but so far those effects have been difficult to demonstrate consistently and sometimes don't seem to exist at all.
Question: It can be concluded from the results of the studies in 2009 and 2014 that _ .
Options: (A) the research findings are practical in indoor decoration (B) solid evidence is inadequate to prove how colors affect us (C) a larger study may help confirm colors' effects on our behaviors (D) walls should be painted different colors depending on different tasks

Answer:
B
