A trick for "Vulnerable" Questions

Bamboosprout

There are two archetypes for answer choices: one that starts with something along the lines of "presume", "assume", or "takes for granted"; another that starts with something along the lines of "ignores", "overlooks", or "fails to take into account".
Most of us can do these questions based on intuition, especially if we use the method that JY taught us. I still visualize the goku doing his kamehameha blast on the car. But for some of the harder, more abstract questions, for me, it helps to realize what these two answer choice stems are saying.
1. When the answer choice says the argument assumes X, the best way to treat this answer choice is as if it were a NA answer choice, and negate it to see if that assumption was necessary, and if so, indeed, without it, the argument is vulnerable.
2. When the answer choice says the argument overlooks X, the best way to treat this answer choice is as if it were a standard weakening answer choice, and just plus the answer choices back into the argument, and see if the kamehameha beam gets bigger or smaller.

Hope this helps, cheers
