I thought that "unless" introduces a necessary condition and you have to negate the sufficient. In the first sentence, it says they cannot attract applicants as sufficient but didn't negate it.

Hi @Tiffanysara,
Thanks for the question! That is how the unless statement works. But here’s the thing: in that statement, “cannot attract applicants” already contains a negation in it. So you have to negate the already-existing negation, and since that’s a double negative, they cancel out. That’s why the sufficient condition doesn’t have a “NOT,” because it would’ve been “NOT cannot,” and so that was just simplified to “attract applicants.”
Hope this helps! Feel free to ask any other questions that you might have.
