I understand why the correct answer is right, but I'm not so sure about the incorrect answers. If someone can check my reasoning and see if I am correct, I would be so appreciative and grateful!
A) This answer choice discusses luck which was never talked about in the exchange. I also think it is wrong because of the word "rarely" while we know that some farms have positive successful rates which the critic argues against, we don't know the rate of the farms success.
B) The critics do not show that the results would be different if twice the amount of farms were studied; they only say the farms studied were the ones that were amenable to natural methods, the results would be the same because of the farms selected under study
C) This is true except for the fact that the critics show justification for their reasoning (farms that were selected for study)
D) They don't demonstrate that natural methods are not suitable for the majority of farms; they only point out that if a self selecting group is used for a study, then it is not representative of all farms using natural methods
E) captures the flaw, the study is saying natural methods success rates is possible, not that it is representative for all farms
