Explanation - Why not A?

Hi! Can someone please provide an explanation for this question - I am really confused. I picked A as my answer but I am not sure how to diagram it or why B is right. Thanks!

Hi @erica-scott,

Thanks for the question! So let’s take a look at what we’re told in the stimulus. Many successful graphic designers began their careers after years of formal training, though a significant number learned the trade more informally on the job. Well, remember that “many” is the same as “some” on the LSAT. So we're told two things here:

Successful graphic designers <—some—> formal training
Successful graphic designers <—some—> Informal learning

Then we’re told that no designer ever became successful who ignored the wishes of a client. Remember, we can diagram “no X are Y” as X —> ~Y. So this is

Successful graphic designer —> ~Ignored wishes of client

So now we need to find something that must be true. Take a look at (A), which tells us that all graphic designers who are unsuccessful have ignored the wishes of a client. THis is

~Successful graphic designer —> Ignored wishes of client

As we can see, this is a mistaken negation! Graphic designers could be unsuccessful for other reasons. For example, they could just suck at what they do. So (A) doesn’t follow necessarily.

(B), on the other hand, does follow. It tells us that not all formally trained graphic designers ignore clients’ wishes. We know this because some formally trained graphic designers are successful, and no successful graphic designers ignore clients’ wishes.

Hope this helps! Feel free to ask any other questions that you might have.
