Question 2 appears to be broken. Specifically, Wyoming displays in the post-quiz answers as though it hasn’t been selected, even when I HAVE selected it. I am quite sure I have not selected it and then de-selected it on several successive tries.
I wonder if it might be better to exclude Maine from the colony question (or to reword the question). It wasn't one of the 13 colonies, but I think it was "in" the original 13 colonies because it was part of Massachusetts.
The rock spire in the picture is Chimney Rock in Nebraska if others are wondering. I've driven through Nebraska probably 10+ times and had to look it up, don't think I've ever heard of it.
