Someone please explain to me why B works.

I seriously don't understand this question, even after the explanation. @Lowri Thomas, please help.

I ruled out B because the stim said it was 10 movies in the past month, B just talks about not renting more than 10 movies.

@ConqueringLSAT It's sufficiency and necessity. So if the first line says Members can get a coupon. And we know Pat can get a coupon, it says nothing about his status as a member or if he is not a member. Affirming a necessary clause doesn't say anything about a sufficient clause. It can be being a member isn't necessary to getting a coupon, by that logical non-members can get a coupon. Get it?

Would you say a good idea is that the sufficient clause is the main point that is "doing" the work? While necessary receives the work?

Is anyone having a hard time with seeing the video?

Grammar is a lil tough

Trying to inch my way to the high 160s. Goal posting my journey.

Ah, okay this seems much more reasonable. It's all about looking for patterns.
