when I read E, I thought it meant they had a poorly controlled study - a good study would mean the same % of participants with a high intake of foods rich in beta carotene are smokers/smoking as are the % of participants with a low intake of foods rich in beta carotene are smokers/smoking... if its a poorly designed study, and they didn't control for that (since smoking obviously is a cause of the outcome being observed, ie: cancer/heart disease), then i can't trust that it was the beta carotene that led to the decrease in cancer/heart disease, which aligns well with the study that saw no correlation between any positive/negative effects on cancer/heart disease as a result of taking supplements. one study's results are untrustworthy (meaning we don't know the relationship) so i know nothing about how bc affects cancer/heart disease and the other study saw no correlation, so i know nothing about how bc affects cancer/heart disease, so technically that resolves the discrepancy that i thought the study was run well and told us that high bc led to decreased cancer/heart disease. i still made the mistaken assumption that we wanted both studies to show that bc decreases cancer/heart disease and kept looking for that, but that's not actually what the q stem is asking for, and now i've learned that lesson

I think (B) is put as a trap answer choice because if you tell me that there are genetic differences among individual shrimp in a specific reef population, then I can assume those differences come from breeding with other populations, which "solves" the conundrum of why they move from reef to reef and don't seem to interbreed with each other if you FORGET that the first sentence says "yeah, okay, even though the average genetic makeup includes that of other reefs... the populations of a shrimp species at eleven different Indonesian coral reefs show substantial genetic differences from one reef to another."

y'all waited til halfway through the condR module to say when you don't need to run the whole module send help

how much caffeine do i need to hit this in the suggested time and why is it 900mg?

how likely is it that we'll get passages like these where so many questions can be answered after reading just one passage?! its crazy how many questions could be answered just on passage A in this first pass of the "split strategy" in the lesson

The way the mouse moves on the screen gives me more anxiety than studying for the LSAT does lolol

will this add to or reduce overall stress lol
