问题    A new study from researchers in Europe claims that the average IQ in Western nations dropped by a staggering 14.1 points over the past century.
   "We tested the【C1】______that the Victorians were cleverer than modern populations using high-quality instruments, namely measures of simple visual reaction time in a meta-analytic study," the researchers wrote in the study, which was published online in the journal Intelligence on Thursday. "Simple reaction time measures correlate【C2】______with measures of general intelligence and are considered elementary measures of【C3】______"
   The results might surprise some. Especially if the researchers were simply measuring visual response times. After all, in a digital world constantly【C4】______for our attention, it would seem people generally respond more quickly to visual stimuli. However, the results appear to indicate something different.
   The Victorian era ran roughly from 1837 to 1901,【C5】______with the reign of England’s Queen Victoria. Some have credited the Reform Act of 1832 with sparking an era of previously【C6】______peace and prosperity in the U. K. The results were measured using data from 1889 to 2004 and were analyzed by Michael A. Woodley in Brussels.
   So why has there been such a【C7】______drop? As UPI notes, previous research studies have found that women of higher intelligence tend to have fewer children on average, meaning that population growth may be driven by those with a lower IQ. And over time, the abundance of less intelligent【C8】______would affect the overall IQ average. On average, the general intelligence of those populations measured【C9】______by 1.23 points per decade. " These findings strongly indicate that with【C10】______to general intelligence the Victorians were substantially cleverer than modern Western populations," the study says.
A)aspect I)insignificantly
B)climbed J)offspring
C)cognition K)respect
D)coinciding L)sharp
E)competing M)steady
F)completing N)substantially
G)dropped O)unprecedented
H)hypothesis
【C9】
选项
答案G
解析 分析句子成分可知，空格处需要填入动词作谓语，而此句是对过去事实的描述，因此需要填入动词的过去时。通过上下文可知，测试人群的智商是与日俱减的，因此G)dropped“下降，跌落”符合语义。
