235. Canadian scientists have calculated that one human being should be struck every nine years by a meteorite, while each year sixteen buildings can be expected to sustain damage from such objects.

请问D比C好，是因为 被动句式与后面的平行吗？我觉得C很简洁清楚。

OG的解释：

1。The phrases equivalent to in A, the equivalent of in B, and equal to in C have too broad a range of meanings to be used precisely here: that is, they can suggest more than merely numerical equality. Also, as quantitative expressions, equivalent and equal often modify nouns referring to uncountable things, as in “an equivalent amount of resistance” or “a volume of water equal to Lake Michigan.” To establish numerical comparability between groups with countable members, the phrase as many as is preferable. Choice D, however, uses this phrase improperly in comparing eight million people to enrollment, not to other people. The comparison in E, the best choice, is logical because people is understood as the subject of are enrolled。

2。Choices A, B, and E can be faulted for using should in place of will to indicate future occurrences: should carries the suggestion, especially unwarranted in this context, that the Canadian scientists are describing what ought to happen. The phrase once in every nine years is needlessly wordy in B and C. Also, the language of C implies more than can reasonably be maintained: i.e., that a meteorite will strike one person, and no one else, exactly once during every nine-year period. Choice D is best: the phrasing is concise and free of unintended suggestions, and the use of the indefinite article in a human being is appropriate for describing what is expected to be true only on the average.
