答案E

解析 In the sentence as written, the referent of the pronoun they is unclear. It may look, at first, as if the referent is the noun phrase Avalanches... 1910. However, this does not work as intended: obviously, avalanches that occurred at the turn of the nineteenth century cannot now be controlled. It is therefore clear that they does not refer correctly.
A    In this choice, the pronoun they does not refer correctly.
B    In this choice, the pronoun they does not refer correctly. Furthermore, it unnecessarily uses the passive form people... killed by avalanches.
C    In this choice, the pronoun they does not refer correctly. Furthermore, it unnecessarily uses the passive form people... killed by avalanches.
D    In this choice, the verb form have been
killed suggests a recent event that perhaps continues to the present. It would be inappropriate to use this to refer to events that happened near the turn of the nineteenth century. Furthermore, it unnecessarily uses the passive form people... killed by avalanches.
E    Correct. This choice avoids the unclear
pronoun and uses the active form glaciers... killed, which produces a simple and rhetorically effective sentence. Furthermore, the phrase such avalanches refers, as intended, to actual or possible avalanches in more recent times than those mentioned in the sentence.
The correct answer is E.
