13.   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?

(A) If a manufacturer uses shoddy materials to make a gadget, the gadget is likely to break quickly.

(B) If a gadget breaks quickly, it was probably manufactured in East Golo.

(C) If a kitchen gadget was manufactured in East Golo, it should not be sold in this country.

(D) If everything that is manufactured in East Golo breaks quickly, then kitchen gadgets manufactured in East Golo are likely to break quickly.（B）

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

答案是B, 但A为什么不对啊?

gadget 坏了,   它是劣等的,因此gadget 一定是East Golo产的.

assumption: 如果东西是坏很可能是East Golo 产的；

注意:shoddy 是指假的；冒充的；劣等的
