问题 Marine biologists consider sea otters______eaters because otters select only two or three kinds of prey out of thirty potential food sources.

选项

答案 B，C

解析 because说明前后同义重复。空格与select only two or three kinds of prey out of thirty potential food sources(在30科潜在的食物来源中只选择两三种食物)同义重复。irregular不规则的，discriminating挑剔的，finicky挑剔的，carnivorous食肉动物的，temperate有节制的，abstemious有节制的。答案选BC。注：这里temperate和abstemious是干扰项，同表示“有节制的”。
