Why did I find the "hardest" difficulty question the easiest out of all SA so far, but severely struggle with the 1-4/5?????? Makes no sense.

OMG, I'm featured in a question!

I actually did guess something extremely similar to C upon reading the stimulus. I haven't been doing the charting or alternative hypothesis for any of these, and have been doing decent on this section. But with that, I do not see how C was something that we "probably didn't think of". I usually do not see the common sense in any of these questions lol, but this one felt very obvious to me. Hopefully it carries for the rest of the "non-causal" questions.

Guess I'm not getting any NA right on the test either lol
