I have an LSAT question that I don't know how to answer. Can someone explain it? It's this one here. I am paraphrasing from memory.
Ed: President X said that he would would sanction Latveria if they implemented Enhanced Currency. However, they implemented Enhanced Currency, and he didn't sanction them. That makes him a liar.
Fred: Latveria's implementation of Enhanced Currency actually helped us, and he clearly didn't mean he would sanction Latveria if they did something to help us! So he is not a liar.
Ed and Fred disagree on which of the following?
a) Whether President X lied.
b) Whether President X's promise applied even in circumstances where Enhanced Currency helped us.
