Question 17 and 18 are based on the following reading passage.

“Scientists have long known that reefs are healthier when a large number, or ‘high biomass,’ of plant-eating fish graze their surfaces,” said Doug Rasher, senior author of the study and a senior research scientist at Bigelow Laboratory. “However, this study revealed that having a diverse portfolio of those fish species on the reef is equally important to keeping reefs well grazed and hospitable to baby corals.”

The findings have significant implications for the management of tropical fisheries. Many herbivores, such as parrotfish and surgeonfish, are eaten by people across the Caribbean. Management plans often focus on sustaining a given number of herbivores on a reef, and not necessarily promoting species diversity within the herbivore community.

The research described in the passage supports which of the following claims about Tropical fisheries?

(A) Tropical fisheries are well managed by the authorities.
(B) People across the Caribbean should stop eating fishes.
(C) parrotfish and surgeonfish should only be eaten by People across the Caribbean.
(D) Management of tropical fisheries should be strengthened for good health of coral reefs.
(E) The Health of coral reefs has nothing to do with the management of tropical fisheries.


Answer: (D)

Explanation: Management of tropical fisheries are very important as only particular kind of parrotfish and surgeonfish are mostly eaten by people across the Caribbean and it is affecting the health of coral reefs.
So, option (D) is correct.
