Am I dumb for not assuming that this "prolonged darkness followed by exposure to sunlight" was on a 24 hour day/night cycle?

Shouldn't never be listed as a logical indicator in group 4 (negate, necessary?)

#4 I'm a little confused. Wouldn't the necessary condition be "internally consistent" in order to make the "scientific theory plausible" (sufficient)? It seems like we have been following sufficient > necessary so this one is throwing me off because I had internally consistent > plausible..

I think it depends. First time I took it, I got it because I wasn't sure how I was going to do. Next time I don't think I will use it.
