Im confused on this one for a weird reason, I didn't choose B because in the stimulus it says the the hypothesis is undermined when in the stimuli it says the hypothesis is likely false. I am supposed to equate undermined = false. Couldn't something that is undermined be true? Maybe I am being dumb.

I was thinking this as well, though in the grammar section he mentions that "most" can actually mean up to 100%. I think its 51-100%. So it likely to be true that all of them were killed. Also In question E, the answer choice says "in or near" which likely means they all died compared to, for example, "in, near, and a few far away" or something.

Me too!! it helped to highlight the conclusion in both arguments for me.
