Question ID:PT62 S4 Q1 Passage:Marine biologist:  Scientists have long wondered why the fish that live around coral reefs exhibit such brilliant colors. One suggestion is that coral reefs are colorful and, therefore, that colorful fish are camouflaged by them. Many animal species, after all, use camouflage to avoid predators. However, as regards the populations around reefs, this suggestion is mistaken. A reef stripped of its fish is quite monochromatic. Most corals, it turns out, are relatively dull browns and greens. Stem:Which one of the following most accurately expresses the main conclusion drawn in the marine biologist's argument? Correct Answer Choice:CChoice A:One hypothesis about why fish living near coral reefs exhibit such bright colors is that the fish are camouflaged by their bright colors. Choice B:The fact that many species use camouflage to avoid predators is one reason to believe that brightly colored fish living near reefs do too. Choice C:The suggestion that the fish living around coral reefs exhibit bright colors because they are camouflaged by the reefs is mistaken. Choice D:A reef stripped of its fish is relatively monochromatic. Choice E:It turns out that the corals in a coral reef are mostly dull hues of brown and green.
