I first made the choice of A without reading the explanations from each of you. I agree with Roberchu and ReedSong. Reed explained very well I think. The author is trying to discredit the fundraisers in this case. If C was correct, as Reed points out, 80% success rate would have come from the less likely donors, thus weakening the argument. As the argument points out, the success rate for people who never donate before should be quite low, most likely below 80%. If A is correct, the 80% success rate is apprarently not for those less likely donors, but the most likely donors. Therefore, the effort of the fundraiser is discredited. |
