Got this one wrong while practicing. So I figured I'd give it a shot here. I think I understand why I got it wrong and why the 4 AC's are wrong. I think we are being asked for the argument structure here...
Argument summary: Researchers throughout the years, investigating telepathy, have not been able to attain definitive evidence confirming its existence. Regardless there are some who believe in it since SOME research supporting it does exist. Despite that, it can be shown that other explanations that comply with the known laws can be given. So its too early to conclude that telepathy is another way to communicate.
(A) is correct because the author mentions that there are some researchers who believe in telepathy because of some evidence but quickly dismisses this because other explanations can be given that are more realistic. To me, thats calling the evidence presented inadequate.
(B) I found no mention of any experiments in the stimulus
(C) The author didn't overgeneralize anything. Plus, there was no actual, specific, evidence brought up for either side of the point.
(D) I picked this during practice. I thought it was right since the part in the conclusion that says "alternative means of communication" was not mentioned or in my mind even implied in the stimulus. I didnt think I needed to assume that telepathy is an actual alternative way of communication.
(E) He did offer support to his conclusion by shooting down other possible evidence and showing that there hasn't been any confirming evidence.
Feel free to pick apart my explanations here! Also an explanation as to what the phrase "alternative means of communication" has to do with the stimulus would be nice
Thanks guys!
