Biconditional Statements.

[LJHUNTZ]

Good afternoon,

After reviewing lesson 2, I was curious about something regarding biconditional statements.

How often will the exam explicitly present biconditional statements using indicators such as "if and only if", "vice versa", "otherwise not", etc. in comparison to just presenting two conditional statements that together combine into a biconditional?

For example, will the stimulus present the biconditional A <-> B using terminology, or will we have to identify the biconditional by identifying the A->B and the B -> A ?

I hope this made sense and any elaboration would help. This is all based on curiosity as the plan is to be able to identify the biconditional through proper diagramming, even if not directly presented.

Hey L,

The concept doesn't come up often, but in LR it's usually "if and only" or some variant. In LG, it can be either method.

Thanks!
