3.     That gadget I bought for the kitchen last week has already broken. It’s just another example of the shoddy products that we are seeing more and more of these days. The thing was probably manufactured in East Golo.

Which one of the following is the best expression of an unstated premise that underlies the author’s reasoning in the passage?

(E) Nothing that is manufactured in East Golo can be expected to last more than a week.

A,D E都错在哪里?像这样的题目通常nn们都怎么分析的?

这里要用到三段论的知识. For instance:

premise 1:    Girls are jealous.
premise 2:    she is a girl.
conclusion:   She is jealous.

上面这道题目缺的就是相当于premise 1的东东

Gadgets produced by E.G break easily. (answer, i.e. absent premise)
The gadge i bought breaks/broke easily.(given premise)
The gadget is probably a product of E.G.(given conclusion)
