Using Negation for Necessary Assumption Questions on the LSAT

If you have been preparing for the LSAT for some time, you would be well aware that the necessary assumption questions from the logical reasoning section is one of the toughest question types to master. These type of questions present an argument and the answer choices present the correct assumption for it. Even if you have done lots of practice, it is easy to commit mistakes.

Identifying the assumptions can be extremely tough. Many students also make the classic mistake of brining in their own assumptions to the question. A great way of tackling these necessary assumption questions is through negation. Remember, that this technique is only for those of you who have already been preparing for the LSAT for some time. If you have just started preparing for the exam, take some time to understand this question type before using this approach to solve the problem.

Now, you know that for an argument to be valid, you need to have a correct assumption. That’s the secret! Using this insight, if you negate an assumption and the argument ceases to be meaningful, you know you have arrived at the right answer choice. However, you should not use negation for all assumption questions and answer choices. Remember that negating every answer choice will also take up a lot of your time. Use negation only when the answer choices are really close and cause confusion.
