Okay, I have a quick question. I seem to be missing something from what I read TLS's article "A lesson in Conditional Reasoning," and what The Princeton Review game seems to be indicating. If I understood the article correctly, the antecedent always follows the if statement, and thus comes first in the symbolization of the conditional statement.
Example: If A is displayed, then neither B nor L can be displayed. A------> ~B and ~L
In game #5 (pg. 187) in 2012 PR LSAT, the 2nd conditional statement is, "B is displayed only if D is displayed." Which, if I understanding the article on here should be symbolized as follows: D---->B.
However, on the game walk through, it displays this statement oppositely, B-----> D.
I think I am clearly misunderstanding something here. Can somebody help me understand what I am missing?
Thanks

"Only if" is a necessary condition indicator.
As such, "B only if D" means:
B ---> D
The book is correct.

Take this statement: "I'll date her only if she's a model."
This means, if I date her, then she must be a model.
Date -> Model
This doesn't mean: if she's a model, then I date her.
There are thousands upon thousands of models. I just don't have the time to date that many girls at once.
