Rate the following argument fragment on its writing, argument, and language skills:
Evidence: A student may get straight As one term but in the next term may get straight Cs. That would mean the activities would have an inconsistent flow of students for every term. The students who had improved their average would join their respective clubs but the students who had not would be forced to withdraw from their activities. The sports teams would fail because every player they got with the new term would not be as practised as the ones which they had from the old term. And what if their all-star line-up could not retain the necessary grade point average? Then victory for our sports teams would almost be impossible. I do not doubt the skills of the students within our school, but skill given and skill learned are to different things to consider. A person who is not great at basketball but who goes to every practice and tries as hard as he can at home might as well match a natural-born super star at basketball who doesn't practice due to arrogance. Which also brings me back to how such a change would be unfair.

Score: 2
