sk05I see what you mean about E, but we don't know that kids choose to become farmers because those around them are farmers. It seems more likely that these kids come from farming families, in which farming may have been the plan all along. Also, E is telling us that this farming aspect may be warping the data around college attendance, but it doesn't tell us whether families will be choosing between urban private schools and rural public schools. Maybe someone who is considering private school is NOT in a rural part of the county, and would not send their kid to a rural public school.
The problem with D is that it isn't enough to overcome what we know--that fewer kids from public schools go to college. Despite the sports, public schools have a lower college attendance rate, so it still seems that private schools have an advantage. Maybe they do more of other activities (debate team, internships, etc.) that increase kids' chances even more. In general, beware of any use of ONE comparison ("We have more sports, and those are good!") to establish or strengthen/weaken a definitive evaluation ("Our school is better for getting into college.") What if I said that movie theater popcorn was better for you than broccoli because it has more protein, which is important for your body? The premise is true, but the conclusion, sadly, is not.
