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.

Summarize Argument: Counter-Position
The marine biologist claims the suggestion that the fish who live around coral reefs are colorful because the coral reefs are colorful, and it allows them to camouflage, is mistaken. It is the fish, not the coral, that are colorful. The coral itself is monochromatic and made up of dull browns and greens.

Identify Conclusion
The conclusion is the marine biologist’s refutation of the hypothesis about colorful reefs and camouflage: “this suggestion is mistaken.”

A
One hypothesis about why fish living near coral reefs exhibit such bright colors is that the fish are camouflaged by their bright colors.
This rephrases the suggestion in the context that the marine biologist refutes. She is saying this is inaccurate because the reefs are not actually brightly colored.
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.
This is context for the mistaken argument. It is reasoning that supports the use of camouflage, but it ultimately does not apply because the reefs are not brightly colored.
C
The suggestion that the fish living around coral reefs exhibit bright colors because they are camouflaged by the reefs is mistaken.
This accurately rephrases the conclusion. “It” - the suggeston that the fish are brightly colored because they camouflage with brightly colored reefs - “is mistaken”
D
A reef stripped of its fish is relatively monochromatic.
This is support for why the bright colors of the fish would not actually be camouflaged by the reefs.
E
It turns out that the corals in a coral reef are mostly dull hues of brown and green.
This is more support that shows why the reef is monochromatic and not brightly colored. This further supports that the brightly colored fish would not be camouflaged by the reefs.
