单选题
Since "special creationism" was an ideological target of Darwin's, he found himself in a
quandary
. Although he did not abandon his theory, he admitted that natural selection played a much smaller part in evolution than he had previously claimed.
【正确答案】
C
【答案解析】解析：四个选项的意思分别是：aversion厌恶；stimulus刺激物；dilemma进退两难的局面；deterrent威慑。句意是，虽然“特殊神创论”是达尔文的意识目标，但他发现自己处在两难的境地。虽然他没有抛弃他的理论，但他承认，自然选择在进化中的作用比他之前声明的要小很多。所以正确答案是C选项，如：She was in a dilemma whether to stayat school or get a job．(是继续求学还是找工作，她感到难以决定。)
