Thank you. This helps.
One thing I do to determine if an answer is sufficient is ask for every single answer -- could this lead to the conclusion without being required for the conclusion to happen?
Would you mind giving me an example of this?
Again, I think this is a questionable approach, because the Sufficient answer might ALSO be something required for the conclusion to happen.
However, to go back to my hypo --
If the Stimulus involves a premise that the movies cost $10, and the Conclusion is that ChiGirl can afford to go, and you have an answer choice "A" that says ChiGirl has $20, then we know Choice A is a Sufficent Assumption, because it would clearly be enough to justify the Conclusion.
On the other hand, it's clearly not required, as you could still go to the movies even if you didn't have $20. So we know it's not a Necessary Assumption.
