I chose C and I can kind of understand how D might be a better option because it provides an alternate explanation for the phenomenon described. However, why would it weaken the argument if one twin watched the other twin?
If the conclusion drawn is that is that â€œwatching a recording of yourself exercising can motivate you to exercise moreâ€ and we're trying to weaken that by saying that an alternate explanation is that anyone watching themselves do something might over report how much they do it, why are we talking about twins.
I felt like C would suggest that the conclusion is not true for everyone.
