Which are negative impacts that the internal combustion engine has had on society?

A. high power and health problems

B. noise pollution and health problems

C. efficient travel and noise pollution

D. efficient travel and high power

B, c and d are positives and a has high power a plus next to a negative, so B is the only one with two positives.

B) Noise pollution and health problems.

The internal combustion engine is behind virtually every form of high-speed travel that we have today, from early planes to cars to trains. With this advancement in technology have come some drawbacks.

2 of these drawbacks are noise pollution and health problems. Health problems are due to more pollution in the air, and less directly, higher rates of obesity due to a less active lifestyle. Noise pollution is quite obvious, these machines make loud noises that are unpleasant to listen to.

Keep in mind that although every option listed is an impact of the internal combustion engine, B is the only one that lists two negative impacts.
