The correct answer is: Fine arts classes hone observational skills that foster academic success.
Another word for "claim" is "argument." The support is exactly that: something that upholds this argument to make it convincing. In other words, supporting evidence answers "why." In this case, the question is: Why should every elective curriculum include a variety of choices in the fine arts? The correct answer must be logical: Because fine arts classes hone observational skills that hone academic success. This is clearly a positive that reinforces the main argument.
