据警察局提供的统计数字显示，汽车防盗装置降低了汽车被盗的危险性。但是汽车保险业对被盗汽车的统计研究则声称，装备了防盗装置的汽车反而比那些没有装防盗装置的汽车更有可能被偷。下面哪一条如果正确，最能解决上述的明显矛盾( )

A. 被盗汽车的失主几乎总是在案发以后立即向警局报告失窃事件，但是却倾向于延缓通知他们的保险公司。他们希望他们丢失的车能被找回来：
B. 大多数被盗的汽车都没有装备汽车防盗装置，而大多数装备了汽车防盗装置的汽车都没有被盗。
C. 最常见的汽车防盗装置是可听得见的报警器，这些报警器对每一起实际的试图偷车事件通常发出10个虚假警报。
D. 那些最有可能给他们的汽车装备防盗系统的人都是汽车特别容易被盗的人，且都居住在汽车被盗事件发生率最高的地方。

Youth Emancipation in Spain The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest. Around 55 percent of people aged 18-34 in Spain still sleep in their parents’ home, says the latest report from the country’s state-run Institute of Youth. To coax(劝诱) young people from their homes, the Institute started a "Youth Emancipation(解放)" programme this month. The programme offers guidance in finding rooms and jobs. Economists blame young people’s family dependence on the precarious(不稳定的)labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000. Cultural reasons also contribute to the problem, say sociologists(社会学家). Family ties in south Europe—Italy, Portugal and Greece—are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Key for Understanding". "In general, young people in Spain firmly believe in the family as the main body around which their private. life is organized," said Minguez. In Spain— especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews(外甥/侄子) all living on the same street. They regularly get together for Sunday dinner. Parents’ tolerance is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules. "A child can arrive home at whatever time he wants. If parents complain he’ll put up a fight and call the father a fascist," said Jos6 Antonio Gomez Yanez , a sociologist at Carlos III University in Madrid. Mothers’ willingness to do children’s household chores(家务) worsens the problem. Dionisio Masso, a 60-year-old in Madrid, has three children in their 20s. The eldest, 28, has a girlfriend and a job. But life with mum is good. "His mum does the wash and cooks for him; in the end, he lives well," Masso said. It can be inferred from paragraph 5 that family ties are stronger in Portugal than in

A. Greece.
B. Finland.
C. Spain.
D. Italy.

一群在实验室里研究老鼠体内的钙的新陈代谢的科学家发现，去除老鼠的甲状旁腺可以导致老鼠血液中的钙的水平比正常水平低得多。这个发现使科学家们假设甲状旁腺的功能是调节血液中的钙的水平。当钙的水平降到正常范围之下，它就会升高钙的水平。在进一步的试验中，科学家们不但去除了老鼠的甲状旁腺，而且去除了它们的肾上腺，他们出乎意料地发现老鼠血液中钙的水平的下降比单是去除甲状旁腺时慢得多。下面哪一项如果正确，能与科学家们的假设相一致地解释那个出入意料的发现( )

A. 肾上腺的作用是降低血液中钙的水平。
B. 肾上腺与甲状旁腺在调节血液中钙的水平时作用是一样的。
C. 甲状旁腺的缺乏能促使肾上腺增加血液中的钙的水平。
D. 如果只是把老鼠的肾上腺去除，而没有把其他的腺移去，这只老鼠的血液中的钙的水平将会维持不变。

对两个国家居民平均生活水平的比较可以反映居民获取产品和服务的相对情况。以一国货币表示的其居民的平均收入的可靠数字可以轻易地得到。但是从这些数字中很难得到平均生活水平的准确比较。这是因为：下面哪个如果正确，能最好地完成以上论证( )

A. 通常没有数字来比较为购买一定数量的产品和服务需要花费多少两种不同的货币。
B. 同样工作的工资水平，因依赖于文化和纯粹的经济因素而在各国之间差异很大。
C. 这些数字必须用一国的国民总收入除以其人口来计算。
D. 获取产品和服务的相对情况只是决定生活质量的若干相关因素中的一个。
