Trying to do it in my head gave me a headache lol but got it right.

I think I am trying to attack the conclusion that the programs should be expanded instead of the assumption that the better performance is due to the programs themselves, not some other factor.

The thing that trips me up is that to me B is strengthening the conclusion of why these programs should be implemented. I am not doing the best in these and not will probably have to backtrack which I did not want to do. :( these "weakened" arguments are just not clicking for me

I am interested! Also reading the loophole :)
