单选题 Some anthropologists claim that a few aps have been taught a rudimentary sign languages, but skeptics argue that the apes are only __________ their trainers.
【正确答案】 A
【答案解析】[解析] 动词词义辨析。Some anthropologists的看法是apes(猿)已经学会了a rudimentary sign language，那么据此判断后文提到的skeptics的看法应该与此不同，甚至是相反，根据argue后面宾语从句的主语apes和宾语their trainers的信息判断，二者之间的关系是前者模仿后者，符合句意的是A项。condoning“宽恕；赦免”；acknowledging“承认”。
