In explaining why the AC was correct for a particular Necessary Assumption question, JY said: "This answer choice is great because it states the assumption in a weak way. For Necessary Assumption questions, the LSAT writer's are weary of using language that is too strong... because if they write something that is too strong, it's not necessary."
I can just accept the italicized statement as true and move on but does anyone care to expand on this and explain why it is so?
For reference, the correct answer choice said "can be" (as opposed to, perhaps, "must be").
I understand why conditional language is an indicator of a Sufficient Assumption correct AC (because it bridges premise A to conclusion B ) but I am not fully grasping why, as JY mentioned, we should steer clear from conditional language or language that is "too strong" within Necessary Assumption answer choices.
