Kevin scored 610 on the verbal section and 700 on the quantitative section. Use the standard deviation as a unit of measurement to compare Kevin’s verbal and quantitative scores on the GRE.

Answer 1

It seems like the embedded image files weren't copied over properly.
Regardless, I think the idea here is to see how many standard deviations away from the average Kevin scored on either section, in order to compare his scores. Generally, more standard deviations above the average would be considered better, in this context

Answer 2
