Is it possible to have 2 answer choice that both weaken the argument but to different degree?
Also, for the weakening question in general, if I have to make an additional assumption to believe one of the AC could possibly weaken, then it would generally be wrong, right? Perhaps subtle ones don't necessarily do this..
Am I in the right mindset for this? I would really appreciate if someone could confirm my thoughts on this.
Thank you!! :)
