Contrapositives are logically equivalent, so it would suffer the same defects.

Correlation does not imply causation

OMG! I didn't know. That's perfect! Thank youuuu!

Is there a way that when we take the drills, we don't lose them if we refresh the page or go to the last or next page? Sometimes the wifi disconnects and I have to refresh the page, and I lose the five questions even though I wasn't done blind reviewing them, so I have no clue if I got them right or wrong. It would be helpful if we could see them like we can with the You Trys, even if we move to the net page, and perhaps there could be an option to take five new ones if we wanted to. #help

It is so satisfying when you can eliminate an answer choice just with grammar. Grammar is QUEEN.

I think that because it is a conjunction, A or B --> C, if we get at least one, then we have enough to get to C. We can get both but that would be a plus, we only need one.

I think it would've been different if it said, A and B --> C because in that instance we would have needed to trigger both to actually get C.
