Dec 1994/ Section 2 / Question #26 (Flaw Question)
The Stimulus says:
Premise: A(switch suppliers) --> B (No profit)
Conclusion: B(No profit) --> A(switch suppliers)

(a) The argument is a circular argument...blah blah
(b) The argument fails to establish....a condition under which a phenomenon is said to occur is the only condition under which that phenomenon occurs.

I think A describes 'circular reasoning' which is Premise: A -->B and Conclusion A --> B(Correct me if I am wrong)
but what does B exactly say? Can I use Answer choice B to describe both converse and inverse fallacy?
If a condition(A) is the only condition that results in B, does it mean that "B --> A" is also true?

I am just confused by the wording of the answer choices. I really appreciate if someone can elaborate on these answer choices... Thank you!

### Re: Question regarding Answer Choices

This mistakes a necessary and sufficient condition, which is what B is saying, admittedly in a different way than usual.

So, yes, if it were established that A is the only condition that results in B, it does mean that B--->A is also true, which is what answer choice B is saying.

And you seem to understand what circular reasoning is.
