This one really messed with me since the last question we went over, the correct answer was denying an alternative hypothesis. I got it wrong the first time, but right in the blind review, but don't make the same mistake that I made in trying to look for an answer that denies an alternative hypothesis. I saw someone comment this a few lessons back, but I always find myself getting the hard questions right, but overthinking on the easy ones lol.

I appreciate the feedback. Yes it does help, thank you very much!

What works for me the best is pretending you're talking to the answer and asking it "okay where does it say that in the text?" Oftentimes, the answer is so incredibly similar to something in the text.

I found it useful to kick it up to the domain. You already know you are talking about the traffic engineers increasing the capacity of the bridge, not about any random bridge being increased, you are taking about the Krakk... bridge.

Is saying "inclusive or" the same thing as saying "and or"?

For question #2, why is the first group not "planetary societies will be endangered" and the second group "by impacts from space"? Endangered is referring to planetary societies, not space. So why would we group "endangered" with impacts from space?
