### Lengthy Sufficient/Necessary Assumption

I haven't locked these down yet. When the stimulus is shorter I can easily diagram and get the answer, but when the question are loaded with a lot of information and the answer choices are all conditional statements I just get lost. Is there a better way than diagramming all this information or possibly a method to quickly eliminate wrong answer choices? Any input on dealing with these lengthy questions.

the biggest thing to look for is making sure modifiers, such as "most," "some," and "all," match between the stim and answer choices

For the longer lengthier one's I've noticed that they generally don't require diagramming.

For Sufficient, I just keep an eye out for any jumps in the argument. With short one's this is usually resolved with a conditional but with lengthier passages the assumption is just a regular statement. Could be conditional, but diagramming isn't always needed.

Necessary assumptions? I don't think I ever diagram necessary at all. Just use the good ol' negate and see if it ruins the argument.

Anticipation greatly helps with both type of assumptions.

If I use the negation technique on an incorrect answer choice will it have no effect on the conclusion?

Using the negate test on the 4 incorrect choices will either have no effect or may help the argument. Only the correct answer choice when negated will hurt the argument. The 4 others won't have that effect.

Also, for lengthy sufficient/necessary assumption questions don't forget the importance of needing to locate the conclusion because the correct answer choice will help the conclusion so you need to consider the choices with the frame of mind does this actually help the conclusion?

Hope this helps.

Please be careful to only use the negation test on necessary assumption questions. Read why here:

Thanks for making that distinction LSAT Blog, OP the negate test should be used for only necessary assumption questions.
