@KendallFrancis05 I hear you. You're not alone! Keep pushing and drilling (what im trying to tell myself). Had to just go to sleep and wake up try again haha

I truly have been struggling since WSE now this. Feeling a bit depleted and after trying question after question getting them wrong, not really sure how to switch my approach or understanding. Any advice?

@JPolus sigh same :/ assumed he was a member and that there were just multiple locations

This makes sense definitely was on track with everything... I just confused myself when i did contrapositve. It was initially (/comfortable--->/well designed) trying to understand why i did contrapositive like this: (comfortable ---> well designed) instead of (well designed ---> comfortable). Can some re-explain negation vs contrapositive?

Just to clarify for question 3:

So if you are infected with the virus and if one week has passed then you produce antibodies. So both having virus and after 1 week means it’s necessary to have antibodies

Contrapositive is= if you don’t produce antibodies, then you either don’t have the virus or it hasn’t been more than a week?

I think I’m confusing this because now the contrapositive to me sounds like it’s only necessary to have a virus (no matter how long) or a virus for a week or more long to develop the antibodies.

I guess my question is how do I interpret the contrapositive and connect back to original without changing the meaning the “or” makes me think now only 1 is necessary but in the first it’s like antibodies are necessary when you have both virus after a week. Hope I’m explaining my thoughts right.
