135) Bond's original explanation of Henrich events would be supported by evidence that:
answer: b) the volcanic rock had been scraped from Canadian mountains

Sorry guys, I have the solutions but I still don't get why B is the right answer
My solutions say that if volcanic rock had been scraped from Canadian mountains, then the debris thought to come from Iceland could have came from the Laurentide glacier, and the theory about the Laurentide glacier being responsible for everything would not have been called into question.
But where does it say that the theory about Laurentide glaciers was proposed by Bond? It only says that BEFORE Bond came along, this was the popular theory. As far as I can tell, Bond is the guy who OPPOSES this theory by bringing up new evidence about the Iceland volcanoe debris, so doesn't this undermine him?

Yeah I thought that one was iffy. They based that on Paragraph 4, where an explanation is offered based on Bond's data. So we are suppose to infer that this explanation is Bond's.

I'm glad some other people think that is BS. I was totally confused by that. They never say it was Bond's idea. I spent like 5 min just looking for Bond's first idea so I could figure out which statement supported it.
