Advice on “negation” technique in solving LR necessary assumption (NA) questions

lenarhie2024

Hi everyone! You all may be aware of the negation strategy for required assumption questions in logical reasoning—basically the idea that if you negate an answer choice and the negation weakens the overall argument made, then it is probably the correct answer.

The curriculum explains some specific negations, such as some/none and all/some not. But since these questions are so common and there are so many complex ways to phrase answer choices, I was wondering if anyone had any tips that they use to negate really difficult statements (ie. unless, only if, at least, etc.).

Another part that trips me up with negation is when there are two potential parts of the sentence I could negate. In these cases, which part do you focus on?

Thank you so much!
