Many conceptual categories are parts of dichotomous (distinct and mutually exclusive) pairs: good or bad, right or wrong, rational or irrational, etc. However, advances in scientific understanding have shown some long-held dichotomies to be untenable. Some life forms have characteristics of both animals and plants; also, matter can be converted into energy and vice versa. Ttherefore, dichotomous classifications into mutually exclusive categories should generally be abandoned. Which one of the following exhibits flawed reasoning most similar to that in the argument above? ['This budget is based on the assumption that revenue will increase for the next two years. However, revenue figures for past years show that assumption to be untenable. Ttherefore, this budget should be replaced by a more realistic one.', 'Recent clinical trials have shown that some antianxiety drugs are addictive and can have life-threatening side effects. Ttherefore, the use of drugs for the treatment of anxiety should be discontinued.', "Review by outside consultants has shown that this company should replace all of its computers with more powerful models. Ttherefore, not all of this company's computers are powerful enough.", 'The longer fruit is kept, the more likely it is to become rotten. While these peaches seem to be fine, they have been kept for a rather long time. So it is best to throw them away now before they begin to rot.']
