The question that got me was #3, and I picked B in the initial viewing, and E in the blind review, and I was wrong both times, and now find that D is the correct answer. Can someone explain to me where I went wrong? In all fairness, E was a hail-mary kind of answer as I felt B was the correct one, but an someone explain further how D should have been my choice all along?

The questions with the double premise, while I still managed to find the premise and the conclusion. I did not find the second Premise within the conclusion.

@Hfa So specific assumptions weaken, while general assumptions strengthen.

So what I understand is that the more reasonable the assumption, the weaker the argument, the more arbitrary the assumption, the stronger. I realize there are other factors, but I feel this is a good base to work with, then you follow-up with the same as the Tiger argument, the Mammal assumption and the aggressiveness assumption, where they are more likely to be true than false.

Semantics matter, honestly this is eye opening when it comes down to it.

I fell for 'C' at first,
