杜然的blog——i'm blinded by blackness

这道逻辑题已经让数位朋友彻底崩溃，有兴趣的试一试。

Teachers are effective only when they help their students become independent learners. Yet not until teachers have the power to make decisions in their own classrooms can they enable their students to make their own decisions. Students' capability to make their own decisions is essential to their becoming independent learners. Therefore, if teachers are to be effective, they must have the power to make decisions in their own classrooms.

according to the argument, each of the following could be true of teachers who have enabled their students to make their own decisions, EXCEPT:

a) their studnets have not become independent learners

b) They are not effective teachers

c)they are effective teachers

d)they  have the power to make decisions in their own classrooms

e)they do not have the power to make decisions

为了安慰做不出这道题的崩溃的灵魂，献上笑话一则：

A man is dying of cancer......

Answer: " So when I'm dead no one will dare touch your mom...."
