HAHAHA Nice write up. Dude, I was totally joking. None of the stated things in my OP were true. I made it all up.
Thanks for the advice though, if I ever run into the situation. It sounds like you're pretty familiar with how to catch someone cheating.
*Edit: Except for the necessary/sufficient question. That was a real question.
Hahaha. It was an intriguing story that caught my attention so I figured I'd share some basics that all guys trying to be in a committed faithful relationship can benefit from knowing. Learned all that stuff during a long term led to living together for a while relationship with an Ex girlfriend.
Ok, back to the LSAT. With sufficient assumption questions the correct answer choice provides a premise that when added to the argument/combined with the premises given in the stimulus guarantees that the conclusion MUST BE TRUE/100% deductively valid rock solid true.
One important thing to pay attention to on those when analyzing the argument is whether or not there is a new element/concept/topic/idea in the conclusion that is not included in the premises. If so, the correct answer choice must include that element (it wont always be in the exact same words since LSAT writers like to paraphrase). Any answer choice that does not include the new element is automatically incorrect. There are many sufficient assumption question where that strategy eliminates multiple answer choices, some where it eliminates up to all four incorrect answers.
Necessary assumption questions are a different breed. The correct answer choice DOES NOT have to guarantee that the conclusion is 100% must be true when added as an additional premise to the argument. It will be something that will substantially weaken if not completely destroy the possibility of the conclusion of the argument having a logical leg to stand on if it is not true (hence the negation strategy).
Some necessary assumption questions of lower difficulty level will present a correct answer choice that when properly negated directly attacks the conclusion itself. However, most of them are high difficulty questions without that configuration. The correct answer choice on difficult necessary assumption questions will present a premise that when negated properly and inserted into the argument as another premise will somehow make the argument as a whole fall apart in terms of trying to establish well logically reasoned conclusion based on the evidence presented.
