Recent studies show that despite global efforts to reduce plastic waste by banning single-use plastics, the amount of plastic debris washing up on beaches has not decreased. Evidence of this is the consistent volume of plastic waste found during beach cleanups over the past year compared to the previous year. Nevertheless, environmental scientists have not concluded that these bans are ineffective.
Which of the following would, if true, provide the strongest reason for the scientists' reaction to the findings?
A. The production of single-use plastics has been significantly reduced in most countries over the past decade.
B. The amount of plastic waste produced annually varies significantly from year to year.
C. Many countries have implemented strict regulations against the use of single-use plastics in the past few years.
D. Strong ocean currents this year have carried more debris to coastal areas than usual.
E. Plastic waste can persist in the ocean environment for hundreds of years before decomposing.
Scientists are aware that the decades-long buildup of plastic pollution in our seas has reached a point where every ocean current is carrying the plastic waste to coasts, albeit in varying quantities, as the article's final line, "Nevertheless, environmental scientists have not concluded that these bans are ineffective," makes clear.
(A) is dropped since, even if plastic production has decreased during the last ten years, it will not make up for the pollution from the decade prior or the decade before that.
Because of the statistical nuance, (B) is out of scope and useless in this situation.
Since the reasoning of recent years is insufficient for earlier decades, option (C) is eliminated.
Since decomposition is not our basis for establishing it as proof of a consistent volume of plastic during beach cleanups, (E) is likewise outside the scope.
The answer to the question is, therefore, (D).
