感觉正常难度吧,遇到的题目有一个实在没想清楚瞎选的其他的基本都能推断出来。突然想起来有一个逻辑题是in an experiment, a test is administered to participants without a certain disease. over 2% of the participants show positive results (正常来说没这个病就应该negative). the test is administered to participants with the disease and over 2% show negative results (正常来说有这个病就应该positive)。问assumption。我选的是no problem in the process of test administration (做实验的流程没问题)。 不知道对不对。。
