#feedback - Can you clarify how much of this analysis/low res summaries should be done in our head vs on paper vs. through highlighting the passage? Is this supposed to be a combination of the three or more intrinsically, entirely in our head?

That's one of the flaws in that argument. Notice, though, that the original argument commits the same flaw (income vs wealth). It was trying to get you to notice there is a difference between the two. That difference is one of the ways to match A to the original flawed argument.

Hello, yes I am! I've moved onto the PSA lessons now and am having the same problem on some, but not all of those videos too. I am on a macbook air and on Chrome. Not sure why this problem is occurring on some videos, but not others. I didn't experience it until I got to the WSE lessons so I'm not sure why its only happening now. It doesn't bother me really though so if it's just a me problem, no worries! I will try the steps outlined above by Juliet though!

#feedback I've noticed in the WSE lessons there are some videos without timestamps for each answer. Can this be added?

That was my first thought, but rereading the stimulus, it states that the "only" obstacle is that they refuse to sell. That eliminates the possibility of any other possible obstacles including other buyers. We know that isn't an obstacle, there's only one obstacle. E tells us that the only obstacle will soon be eliminated.

Yes, if it is optional! I'd still like the opportunity to drill without seeing the answer after each question :)

This tripped me up as well. I think "whenever" better aligns with "when" in Group 1, making it a sufficient condition.
