This one definitely forces you to think. It could be that as few as a handful of people said they were most influenced by the bible and 1984 (let's just say 10 and 8, respectively, for simplicity's sake) and the rest are a random menagerie of choices. Well, then the conclusion that a great number of people are influenced by 1984 simply doesn't follow.

This is an apt example of "don't let perfect be the enemy of good." C isn't perfect, but it's the best choice. A and E try to gaslight you. Also, note that (accordingly) throughout the passage, the support references research that doesn't cite being in a legal setting. It makes the "may influence jurors" part of C even stronger.

What helps me, especially with harder NA questions, is to re-read the stimulus as well as the question stem. This question is somewhat unique because it specifically asks about the necessary assumption concerning the copper tools. In this way, B makes the most sense by far.

I'm not here to lick the boot or anything, but saying "I don't know" in response to an incorrect AC in an MSS question is par for the course. We take the stimulus and its info for what it is, and there is little to extrapolate that the incorrect ACs are actually not so. I understand the frustration; this question is difficult, I picked B and got it wrong.

I never really thought about it this way! Extremely helpful! Basically, the strength of the claim/conclusion and its respective language is what commands the threshold of sufficient counter-evidence. Hope that's not a totally convoluted way of putting it.

#feedback Shouldn't the title read "An Organ in a System"?

He can - I was stuck on this for a little bit too. Joffrey could only kill Bran, but that doesn't necessarily imply that he can't kill Robb (B→/R is unsubstantiated). If Joffrey couldn't kill Bran then he has to kill Robb (/B→R); if he doesn't kill either of them, then we are operating outside of the conditions of the prompt - which is why R is the necessary condition in this case. Hope this helps.
