In marine ecology, for decades conservationists maintained that establishing no-take marine reserves was the single most effective strategy for restoring depleted coastal fish populations. However, recent longitudinal studies reveal that surrounding industrial run-off often invalidates the localized protections of these reserves. Because chemical pollutants impair fish reproductive cycles regardless of fishing boundaries, establishing isolated reserves fails to halt population declines unless catchment-wide pollution controls are simultaneously enacted. Therefore, regulatory authorities should reallocate primary funding from reserve enforcement toward watershed chemical management.
In the argument above, the bolded portion plays which of the following roles?
- It provides background context describing a traditional position that sets the stage for the argument's main conclusion.Cevap
- BIt is a premise offered to directly justify the author's final recommendation regarding funding reallocation.
- CIt is an intermediate conclusion derived from recent longitudinal studies to demonstrate the inadequacy of current fishing bans.
- DIt is an objection raised against the author's primary proposal that the argument subsequently attempts to refute.
- EIt provides empirical evidence supporting the claim that industrial run-off impairs fish reproductive cycles.
