Question

what is the best underlying reason that engineering is predicted to be critical to the development of non - fossil sources of energy?
salaries to create and improve alternative fuels will entice many students into engineering.
engineers have the skills to create future alternatives and improve current ones.
environmental activists will force companies to expand the development of alternatives fuels.
the fossil fuel industry itself will begin developing alternative sources.

Explanation:

Engineering involves applying scientific and mathematical principles to design, create, and improve systems. Engineers' skills in innovation, problem - solving, and technical expertise are crucial for developing non - fossil energy sources. Enticing students with salaries (first option) is more of an external incentive rather than the core reason. Environmental activists (third option) and the fossil fuel industry (fourth option) are external factors. The second option directly relates to the engineering skills needed for energy source development.

Answer:

Engineers have the skills to create future alternatives and improve current ones.
