The average temperature of the lobster-rich waters off the coast of Foerkland has been increasing for some years. In warmer water, lobsters grow faster. In particular, lobster larvae take less time to reach the size at which they are no longer vulnerable to preda-tion by young cod, the chief threat to their survival. Consequently, the survival rate of lobster larvae must be going up, and the lobster population in Foerkland’s coastal waters is bound to increase.
选项
A、There are indications that in recent years the fishing fleet operating off the coast of Foerkland has been taking cod at an unsustainably high rate.
B、The increase in water temperatures off Foerkland has not been as pronounced as the increase in average soil temperatures in Foerkland.
C、Because of their speeded-up growth, lobsters now get large enough to be legal catch before they reach reproductive maturity.
D、Even though lobsters grow faster in warmer waters, warmer waters have no effect on the maximum size to which a lobster can eventually grow.
E、Cod are a cold-water species, and the increasing water temperatures have caused a northward shift in Foerkland’s cod population.
答案
C
解析
The argument in the passage concludes that the survival rate of lobster larvae is increasing and that the lobster population will increase. The basis for the conclusion is that the change in the water temperature, by speeding the growth of lobster larvae, has made them less vulnerable to predation by cod. However, Choice C points to a way that the faster growth of individual lobsters could create a threat to the population: lobsters that have not yet reproduced might be large enough to be legally caught. Thus, Choice C weakens the argument and is the correct answer.
Among the other choices, Choice A tends, if anything, to support the passage’s conclusion, by suggesting further reduction in the risks of predation by cod. The other choices have no clear bearing on the argument.
