问题 In general, the tests work most effectively when the qualities to be measured can be most precisely defined and least effectively when what is to be measured or predicted cannot be well defined.

选项

答案一般说来，当要测定的特征能被十分精确地界定时，测试的效果就最佳；反之，如果所要测定和预测的东西得不到明确的界定，那么测试的效果就最差。

解析本句是由and连接的并列结构，每个并列结构中各有一个when引导的时间状语从句。在第二个时间状语从句中有一个what引导的主语从句。
