Can anyone explain why the answer is B?
Also is the conclusion implying causation? or a weak form of causation? because if so , then I can understand why B would be right since it gives an alternate cause for the effect occurring.
I originally picked E because I thought that it rendered the comparison invalid but in fact it does not. Since it says microwavable popcorn weighs more than conventional, it can mean .1 pounds or 4 pounds more. There is a wide range of possibilities so I believe it would not necessarily render the comparison invalid.
Can someone explain why A is wrong too?
Thank you
