this section is absolutely my worst one and it's stressing me out, cause I just can't get it.

I'm so mad, i was in between C and E and ultimately picked E.

I too was between A and E until I remembered that I'm strengthening the hypothesis which is "exposure to germs during infancy"(Causation) and A is referring to the premise not the conclusion.

loved the RRE honestly, my brain made it make sense compared to the other lmao

Got it wrong because I wanted to get it in the time frame, but blind reviewed the fuck out of it and got it right. FINALLY!!!

I picked E because I thought the question was in regards to the first sentence, and when I realized that it was about the second sentence, palm to face emoji.

Yes but that is not inserted by the argument, you are making an assumption by including details from the real world. the focus isn't the audience but the argument and if they don't mention an audience then we shouldn't tailor it to involve an audience.

from what i understand, a structure (support) holds up both the premise and conclusion, if you remove the structure (Support) then the argument falls) because there was no relationship in which the premise was able to provide support for the conclusion.

You can but it then is no longer considered an argument , as it simply becomes a statement.
