In this passage, I picked D because I interpreted Rito using the phrase "serious underestimates" as the severity of the underestimate of the raw numbers, while Hiro uses “surely underestimate” as an acceptance that there is an underestimate but not necessarily accepting of the severity of it.

When I reviewed JY's reasoning, he said that they both thought it was serious, which I can't really seem to understand how it can be interpreted as such.

Can someone help me find out where in my thought process I went wrong? My second choice was the correct answer, and I should have focused on the conclusions in this one, but I need help seeing how both thought it was a serious underestimate. Thanks!
