问题     There is a lot to feel down about this month: the subprime mortgage crisis, stormy, unpredictable weather, rising gas prices, presidential primary free-for-alls. So, it would be easy to believe the theory set forth by Professor Arnall, a researcher from Cardiff University, that the third Monday of the month—a day he calls Blue Monday—will be our most depressing day of the year. Arnall bases his yearly prediction on a formula he developed which factors in the weather, consumer debt from holiday spending and failed New Year’s resolutions and arrives at that conclusion that we will hit rock bottom on Monday the 21st. Aside from the fact that Arnall’s theory has been discounted by many in the academic community, I have got a better way of finding the true nadir of depression: Look to our search behavior.
    In the digital age we are likely to turn to search engines just as often as we would confide in friends and medical professionals to gauge our psychological state. If we think we are suffering from a real bout of the blues or a mental crisis, we are likely to Google the symptoms or find a chat group in the hopes of performing a self-diagnosis. In fact online searches "depression" are among the most popular searched word, sending traffic to the 5,900 sites that we track in the Hitwise Health and Medical category, but the peak is not in January. According to our internet behavior, our depression spikes reliably in mid-November every year, right in time for Thanksgiving, the launch of the holiday season.
    To confirm this timing I took a look from a different perspective. If we are depressed, we are probably also seeking pharmacological help. By aggregating the traffic to the websites of the top antidepressants and charting visits to those sites over the last three years, a very interesting pattern emerges. The spike in traffic to the official websites for drugs like Lexapro, Prozac, Paxil and Cymbalta occurs in late October and early November, two weeks ahead of the height in searches on "depression". It is almost as if people anticipate their holiday depression and start shopping early for their drug of choice.
    Another surprise lies in the demographics of visitors to antidepressant websites—they are not who you would expect. If visitors to Lexapro website, for example, are at all representative of the typical depressed individual, depression during November is an affliction primarily of the young and the old, but not of the middle-aged. The two age groups that account for the largest portion of site visitors are 18 to 24 and over 55. Visitors to Lexapro’s site also tend to have average to above-average incomes: 51% of visitors come from households earning between $60,000 and $ 150,000 per year, while 20% come form households that earn over $150,000—a sample, perhaps, not of the depressed in general, but of those who can afford to seek treatment.
    So, despite the failing economy, the storm of the century here in Northern California, a disappointing roster of presidential candidates and deciding that New Year’s resolutions are not for me this year, I am feeling pretty good about things. If research date is any indication, I am not alone.
By aggregating and charting visits to the antidepressants’ sites, the author intends to ______.

选项 A、expound the reason why the spike in traffic to those sites takes place in late October
B、verify the conclusion about when the peak of "depression" is
C、make a comparison between the different conclusions reached in Paragraph 2 and 3
D、state the fact that people can anticipate their holiday depression

答案B

解析 属逻辑关系题。由题干关键词定位到文章第三段,该段第一句是主题句,同时也是作者所做这些工作的目的,即“to confirm this timing”,也就是得出一个关于最忧郁时间的结论。由此判断,选项A错误,所做这些并不是为了解释其原因。选项C也不正确,作者的目的并不是为了做比较,而是为了确认之前结论的合理性。选项D对应该段最后一句,只是作者从结论中推测出的一种现象,故不合题意。选项B与该段第一句对应,故B项为正确答案。
