Background information：L eaten by humans are more likely to contract gill diseases when sewage
contaminates their water. Under a recent proposal, millions of gallons of local sewage each day would be rerouted many kilometers offshore.
Premise: because hardly any lobsters live long enough to be harmed by those diseases.
conclusion：Although this would substantially reduce the amount of sewage in the harbor where lobsters are caught, the proposal is pointless.
Prephrase: (weaken)
(A) Contaminants in the harbor other than sewage
are equally harmful to lobsters.------------irrelevant
(B) Lobsters, like other crustaceans, live longer in
the open ocean than in industrial harbors.-------------------correct------------- This answer has no impact because the argument is about lobsters that are caught in the harbor.
(C) Lobsters breed as readily in sewage contaminated
water as in unpolluted water.---------------------this seems to support the argument
(D) Gill diseases cannot be detected by examining
the surface of the lobster.-----------the argument does not mention any information about detect G diseases
(E) Humans often become ill as a result of eating
lobsters with gill diseases.----------------this information has been mentioned in the argument.-----------correct
人们吃了带有G病的龙虾而生病，说明龙虾能活的足够长来染上这种病。没有仔细读提！！！

premise：In the two years following the unification of Germany in 1989, the number of cars owned by residents of East Germany and the total distance traveled by cars in East Germany both increased by about 40 percent.
Conclusion：In those two years, however, the number of East German residents killed each year as car occupants in traffic accidents increased by about 300 percent.
prephrase：（explain）many east Germans move to live in the west Germany.
(A) The average number of passengers per car was higher in the years before unification than it was in the two years after.
(B) After unification, many people who had been living in East Germany relocated to West Germany.---------in the above argument, it talked about car occupants of east Germany rather than people who live in east Germany. So this answer is irrelevant.
(C) After unification, a smaller proportion of the cars being purchased by East German residents were used vehicles.
(D) Drivers who had driven little or not at all before 1989 accounted for much of the increase in the total distance traveled by cars.------------because inexperienced drivers would have much more accidents if they drive a long distance than experienced drivers do. So this answer is correct.
(E) Over the same two-year period in East Germany, other road users, such as motorcyclists, bicyclists, and pedestrians, experienced only small increases in traffic fatalities.

background information：Regulations recently imposed by R government call for reductions in the amounts of pollutants manufacturers are allowed to discharge into the environment. It will take costly new pollution control equipment requiring expensive maintenance to comply with these regulations.
Premise：Resultant price increases for R manufactured goods will lead to the loss of some export markets.
Conclusion： annual exports of Risemian manufactured goods will in the future occur at diminished levels.
Prephrase：（weaken）other countries also need the pollution control equipment

Background information：Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat.
Premise：A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat.
Conclusion：Using the new process instead of the old process increases the price of a new aircraft considerably.
prephrase: (WEAKEN) a layer of primer weighs more than a layer of new coating.

Background information:In countries in which new life-sustaining drugs cannot be patented, such drugs are sold at widely affordable prices; those same drugs, where patented, command premium prices because the patents shield patent-holding manufacturers from competitors.
Premise: the practice of granting patents on newly developed life-sustaining drugs were to be abolished everywhere.
Conclusion: future access to new life-sustaining drugs can be improved
prephrase: ( weaken) if has no patents on new drugs, the company will have not enough money to research the new drugs.

nce the crustaceans be contacted by the disease, they will be harmfull to people who eat them,even though they were not harmed by the disease.
is harmed by sewage;a recent proposal:rerouted the sewage many miles away.
remise: it will take costly new equipment to comply with the regulation, making the manufactured good’s price increase.
