问题     For almost two centuries now, scientists have noticed a place’s suicide rate bears troubling links to the changing of the seasons and the friendliness of its climate.
    In 1881, the Italian physician Enrico Morselli noted that suicide rates peak in the summer, deeming the effect "too great for it to be attributed to chance of the human will". Two decades later, the French sociologist Emile Durkheim noticed the same effect—though he also found the suicide rate was higher in Scandinavian countries.
    Even today, CDC data confirms that suicides peak in the United States in the early summer. Now, scientists have identified one more way that climate shapes suicide—and, worryingly, they have projected that it will only become more pronounced as suicide rates rise in a rapidly warming world.
    Unusually hot days cause the suicide rate to rise, according to a study published Monday in Nature Climate Change. If a month is 1 degree Celsius warmer than normal, then its suicide rate will increase by 0. 7 percent in the United States and 2. 1 percent in Mexico.
    " It’s sort of a brutal finding," says Marshall Burke, a professor of earth science at Stanford University and one of the authors of the paper. The finding has anxious implications for a world whose climate is rapidly changing. The authors project that roughly 14,000 people—and as many as 26,000—could die by suicide in the United States by 2050 if humanity does not reduce its emissions of greenhouse-gas pollution.
    It also concludes that humans can do little about this suicide-climate link beyond developing better medical care to address suicide specifically. The normal ways that people adapt to high temperatures generally—by installing air conditioners, for instance—do not seem to affect the suicide rate.
    Suicide is the second most-common cause of death among Americans between 10 and 34 years of age. In other words, more people are dying by suicide than used to.
In Paragraph 5, why does Marshall Burke say it is a brutal finding?
选项 A、Because suicide rate will rise to 0.7% in America.
B、Because climate is rapidly changing.
C、Because as many as 26,000 could die by suicide in the United States by 2050.
D、It is not mentioned in the passage.
答案C
解析 推理判断题。题干的关键词是brutal“残忍的”，根据题干定位到第五段，再分析选项：[A]“因为美国的自杀率会上升到0．7％”，原文是说“上升0．7个百分点”，与原文不符，故错误；[B]“因为气候正迅速变化”，与“残忍”无关，故错误；[C]“到2050年，在美国大约会有多达26 000人可能会自杀身亡”，的确是原文出现的意思；[D]“文中没有提及”，很显然错误。由此可见，最恰当的是[C]。
