How would you know to go looking for contrapositives? Should one be looking for contrapositives once they see conditional indicators or quantifiers? #Help

I was between B and E, but I chose B because E being a comparative statement kinda threw me off. I feel as if the comparative dimesion of the statement is irrelevant. What im not sure about is why that irrelevancy doesn't overwrite it's validity to being an alternate explanasion. #Help

I'm sorry but I feel like the stimulus supports A as an inference / conclusion just as much as it supports D. I also don't see how combining two premise to infer D automatically adds a sense of logic to D.... I personally feel like you can do the same logical math to infer A.

Going back and reviewing this, I think the word "only" is more critical here than what I comprehended in my first pass through.

The oldest fossil found so far is ONLY 55 million years old, which is more than half of Carrillo's estimate. With this evidence and a better understanding of the circumstances, and comparing C's support to O's support, I can see why B is a better answer choice.

Other than reading better, how would I catch this gap in my reading comprehension?

Going from "no special magic" to "flawed mechanism" is a huge jump. I initially interpreted "no special magic" as "inadequate". But just because something isn't good enough means it's flawed?

I was way too focused on reasoning structure here. I picked D because it also had a conditional even though I was able to understand that a flaw that was present was an appeal to authority with irrelevant expertise. I don't understand why I wouldn't also focus on reasoning structure here. Also what is the difference between reasoning structure and reasoning pattern?

@wcameron16376 This is just a really bad analogy.

@corykopicki143 I feel like the same "strengthen by blocking an alternative hypothesis" could also be used to rationalize AC C as the right answer as well.

@ramonpeinado Great explanation here

I don't understand what to attack here. I saw the correlation to causation fallacy. I saw the doubt answer choice B introduced but why would I attack the integrity of the correlative relationship instead of use it as a weapon (Answer choice D) ?
