问题 A long-standing theory about the migration of green turtles was (i)______by an innovative marine biologist who graciously defused potential (ii)______by dedicating her work to the original researcher.

选项

答案B,D

解析 long—standing theory和innovative一起出现,表明原先的理论被颠覆。enhance增强,repudiate否定,instigate煽动/激起。答案选B。defuse表示“平息,抚慰”,因此后面一定是一个不好的东西。acrimony刻薄,approval赞成,attribution归属。答案选D。
