Answer:
Environmental scientists look for solutions to protect the environment, while chemists develop new products.
Explanation:
The last two sentences use the conjunction while meaning <em>whereas</em>, i.e. indicating a contrast. So the purpose of sentences 3 and 4 is to contrast certain things about environmental scientists and chemists. However, the fourth sentence contrasts only <u>level of education</u> required for these jobs.
The third sentence refers to <u>actual</u> <u>work</u> that environmental scientists and chemists do. Therefore, this sentence most accurately describes a way in which the jobs of environmental scientists and chemists contrast.

A is not the answer because that line explains where frogs get their names from, and introduces the topic of bright colors talking about the frog's bright eyes.

C, on the other hand, introduces a new species of frog that is not talked about during the rest of the essay, and it does not support the idea of colors being crucial in the red-eyed tree frog's surivival.
