I see the answer described in answer choice A - A LOT. Can you please explain the difference between A and E? Thanks!

I am happy to explain the difference between A and E. Let’s understand it with examples of what each flawed argument looks like:

A: Treats something that is sufficient to produce a result as if it were necessary to produce that result.

If I eat cake, I become happy.

(Eating cake is the sufficient condition to becoming happy.)

It would be a flawed argument to then conclude that if I am happy, it must because I ate cake! That is treating the sufficient as necessary, when in fact there are a lot of other things that make me happy — like explaining LSAT questions clearly.

E: Treats what could be the effect of something as if it were the cause of that things.

The famous version of this flawed argument is: the rooster crows, and the sun rises. Therefore the rooster’s crow must cause the sun to rise.

Silly, right? It is treating the effect of the sun rising (the rooster wakes up and crows!) as if it is the cause of the sun rising.

Do those different examples help explain the difference between the flaws? Let us know if not!

I seem to like choice A. But I'm still trying to make the connections properly because it seems as if there's a flaw in the conditional logic. Would you be able to break down the connection?
