To assume or not to assume. that is the question

sorrows, sorrows, prayers

I still don't get why B is the answer.

sigh im going to bed

Negating has been a heaven sent when it comes to choosing the correct answer 😭

I wish there were videos to this. I enjoy reading everything but my brain skips stuff when it gets bored and i end up not understanding:

I chose A immediately after reading the stimulus but changed my answer to C after overthinking it. I need to trust my gut more :/

Can anyone explain why A is not the answer and helps explain the phenomenon? I'm so confused

Can anyone tell me why A isn’t the answer? I was in between A and D because both talk about independent stores and in that helped me remove the rest of the answer choices. Is it the Most in A and the No in D that solidify why D is the answer?

I think its making it so difficult to answer these questions is because I've wired my brain to make difficult assumptions and sometimes the most obvious answer choices in other LR questions are the wrong answers. But for this kind of question, simply underlining the 'rules' and looking for the answer that follows those rules makes sense even if it does seem obvious.

so would it be that If disease X is a subtype (secondary) form of disease Y, and disease Y is not linked to the hypothalamus, then disease X would not be linked to the hypothalamus either because both diseases are of same category. Which in then would weaken the argument that the size of the interstitial nucleus, a sub region of the hypothalamus, relies on whether or not of male cats can contract disease X?
