it can definitely be easy to get fooled by sub-conclusions, but what has helped me is what the foundations discussed: Asking how/why in regards to the statement you are reading. If the other lines answer the how and why AND the current statement does not also answer the question why for another statement, then it is the main conclusion. I find that I can pretty much do that sub-consciously now for the most part but for a stimulus that is a bit challenging, simply asking how or why is extremely helpful.

wowww this one got me but the discussion helped a lot. Essentially what is being said is:

Some cultivars of corn are much more closely related morphologically to sorghum than some cultivars of corn are to most other cultivars of corn.

The reason why is is hard to see it initially is because of the way the sentence is structured. It wants you to blindly use the tools without actually thinking of what is being said

number 2 got me...was a good reminder to not coast through the question. I originally misconstrued the authors reporting of the scientists' conclusion as the author's own conclusion which was incorrect

haha this is so cool, it follows the transitive property in discrete mathematics. Hopefully I can start seeing more things that connect to the logic that I have already learned in my major!
