@yam Yeah I didn't see that one coming haha

Does anyone have a link to the Professor Dan Epps lecture? It appears it was not hyperlinked in the lesson.

@haena This is great. Thank you.

This is the first question I've seen where a plurality of respondents chose the wrong answer (myself included). Usually even on the hardest questions a plurality (if not a majority) still land on the right answer. This one's tough.

This question is far out.

I would have expected an answer choice along the lines of "Whether the reed boats work on heavier stones up to 40 tons." or something to that effect
