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.
