单选题 The author states that a supply of non-human workers for low IQ jobs would

A、 substitute them for humans completely.
B、 henefit man mentally and physically.
C、 give rise to the opposition from geneticists.
D、 be a disadvantage to many human workers.

【正确答案】 B

【答案解析】[注释] 作者观点题。本题问：作者认为用猿做智商低的工作有什么好处?第4段第1句写道：“一旦能提供非人类的工人(即指猿)，人类就能有幸不再从事整整一系列的低智商的工作，这对人类在思想上和体力上都有极大好处。”选项[B)符合上面的表述。[A]中有completely，这就绝对化了，故不能入选。注：to one's advantage对(某人)有利：More practice will be to your advantage．(多练习对你有利。)
