Statement 1- All As are Bs

Statement2- All Bs are Cs

Conclusion : All A being C is a possibility.

My question is, since All A being C is a certainty and not merely a possibility, does the conclusion hold true? (Because possibility is probably a subset of certainty??)

Thanks. Any help is appreciated.

Absolutely. In order for something to be true, it has to be possible, and we know from the statements that all As are Cs. Imagine negating the conclusion--"It is not possible that all As are Cs." That can't be right.

However, this is pretty far afield from the GMAT. Does this relate to some trouble you've been having with the test?
