问题 The professor gave______instruction to the whole class so as to make every student understand how to conduct the experiment in the lab.

选项 A、explicit
B、afflictive
C、authoritative

答案A

解析 本题意为“教授对全班进行了明确的指导,好让每位学生知道如何在实验室做这个试验。”explicit的意思是“明确的”;afflictive的意思是“折磨人的”;authoritative的意思是“有权威的,官方的”;oblivious的意思是“忘却的,健忘的”。四个选项中只有A项为正确答案。
