【考英文】點解錯?

I think you guys are missing the point. I have a kid, this is a typical math question for the 1st or 2nd grade in the US (based on the usage of miles and yards). If you look at what is asked in the 2nd question (just simple addition), you can tell it is part of a Math test or homework for lower grades. It has nothing to do with running. This is a test on sense of scale of various mesaurement units. This is equivalent to asking a child what is the best estimate of amount of water one may drink at lunch: an oz, a cup, or a gallon?
