Lobsters and other crustaceans 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. Although this would substantially reduce the amount of sewage in the harbor where lobsters are caught, the proposal is pointless, because hardly any lobsters live long enough to be harmed by those diseases.
Which one of the following, if true, most seriously weakens the argument?
A
Although the danger of global warming has not reached the alarming levels of the 9th and 14thcenturies it is natural for people to look askance at the growing number of power stations and carbon monoxide emissions
B
New research shows that the Earth was much warmer in earlier centuries which contradict those who are worried about the increase in man-made pollution and the consequent global warming.
C
With the rampant increase in external sources of pollution, the threat of global warming looms large over people’s heads. However, this will be dispelled by the results of a recent study.
D
Global temperature has been a matter of concern for scientists and environmentalists alike. However, while the latter worry more, the former are busy discovering evidence that quells the fears of global warming.
