The “suicide wave” that followed the United States stock market crash of October 1929 is more legend than fact. Careful examination of the monthly figures on the causes of death in 1929 shows that the number of suicides in October and in November was comparatively low. In only three other months were the monthly figures lower. During the summer months, when the stock market was flourishing, the number of suicides was substantially higher.
Which one of the following, if true, would best challenge the conclusion of the passage?
(A) The suicide rate is influenced by many psychological, interpersonal, and societal factors during any given historical period.
(B) October and November have almost always had relatively high suicide rates, even during the 1920s and 1930s.
(C) The suicide rate in October and November of 1929 was considerably higher than the average for those months during several preceding and following years.
(D) During the years surrounding the stock market crash, suicide rates were typically lower at the beginning of any calendar year than toward the end of that year.
(E) Because of seasonal differences, the number of suicides in October and November of 1929 would not be expected to be the same as those for other months.
