19/2/7 Politician: Now that we are finally cleaning up the industrial pollution in the bay, we must start making the bay more accessible to the public for recreational purposes. Reporter: But if we increase public access to the bay, it will soon become polluted again. Politician: Not true. The public did not have access to the bay, and it got polluted. Therefore, if and when the public is given access to the bay, it will not get polluted.
Which one of the following most closely parallels the flawed pattern of reasoning in the politician's reply to the reporter?
(A) If there had been a full moon last night, the tide would be higher than usual today. Since the tide is no higher than usual, there must not have been a full moon last night.
(B) The detective said that whoever stole the money would be spending it conspicuously by now. Jones is spending money conspicuously, so he must be the thief.
(C) When prisoners convicted of especially violent crimes were kept in solitary confinement, violence in the prisons increased. Therefore, violence in the prisons will not increase if such prisoners are allowed to mix with fellow prisoners.
(D) To get a driver's license, one must pass a written test. Smith passed the written test, so she must have gotten a driver's license.
(E) In order to like abstract art, you have to understand it. Therefore, in order to understand abstract art, you have to like it.
我认为答案是b但给的答案是c，为什么呀？
19/2/10If the needle on an industrial sewing machine becomes badly worn, the article being sewn can be ruined. In traditional apparel factories, the people who operate the sewing machines monitor the needles and replace those that begin to wear out. Industrial sewing operations are becoming increasingly automated, however, and it would be inefficient for a factory to hire people for the sole purpose of monitoring needles. Therefore a sophisticated new acoustic device that detects wear in sewing machine needles is expected to become standard equipment in the automated apparel factories of the future.
Which one of the following is most strongly supported by the information above?
(A) In automated apparel factories, items will be ruined by faulty needles less frequently than happens in traditional apparel factories
(B) In the automated apparel factories of the future each employee will perform only one type of task.
(C) Traditional apparel factories do not use any automated equipment.
(D) The needles of industrial sewing machines wear out at unpredictable rates.
(E) As sewing machine needles become worn, the noise they make becomes increasingly loud.

19/2/19The Volunteer for Literacy Program would benefit if Dolores takes Victors place as director ,since Dolores if far more skillful than Victor is at securing the kind of financial support the program needs and Dolores does not have Victor's propensity for alienating program's most dedicated volunteers.
The pattern of reasoning in the argument above is most closely paralleled in which one of the following?
(A) It would be more convenient for Dominique to take a bus to school than to take the subway, since the bus stops closer to her house than does the subway and unlike the subway the bus goes directly to the school.
(B) Joshua's interest would be better served by taking the bus to get to his parent's house rather than by taking an airplane, since his primary concern is to travel as cheaply as possible and taking the bus is less expensive than going by airplane.
(C) Belinda will get to the concert more quickly by subway than by taxi since the concert takes place on a Friday evening and on Friday evenings traffic near the concert hall is exceptionally heavy.
(D) Anita would benefit financially by taking the train to work rather than driving her car since when she drives she has to pay parking fees and the daily fee for parking a car is higher than a round-trip train ticket.
(E) It would be to Fred's advantage to exchange his bus tickets for train tickets since he needs to arrive at his meeting before any of the other participants and if he goes by bus at least one of the other participants will arrive first.
