Question

multiple - choice question
environmental engineers use ____________ combined with engineering practices to come up with solutions to environmental problems.
physics and math
chemistry and biology
aerodynamics and fluid flow

Explanation:

Environmental engineers often use principles from chemistry to understand chemical reactions in environmental systems and biology to study ecological aspects. Physics and math are also important but chemistry - biology combination is more fundamental for many environmental problems. Aerodynamics and fluid - flow are more specialized areas within engineering and not the most general combination for environmental problem - solving.

Answer:

B. chemistry and biology
