Answer choice B

Can someone explain the negation for answer choice B? I thought unless negates the sufficient condition?

Hi @lxnxrd19,

Thanks for the question! So you’re right about diagramming unless. The statement would be diagrammed

~Information accurate v ~Information concerns public safety —> ~Order her to reveal identity

The negation would be that if the information wasn’t accurate or the information didn’t concern public safety, it wouldn’t necessarily follow that the journalist’s editor would not order her to reveal the informant's identity.

This is very complicated, but here, you don’t really need to negate. I’m assuming you’re trying the negation test, but remember, this is a strengthen with sufficient premise question, and you don’t use the negation test for those questions.

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