Explanation:

Question 5

A smart thermostat is designed to control heating and cooling systems efficiently by adjusting temperature settings based on user preferences or environmental conditions. A wind turbine generates electricity, a hydroelectric dam produces hydroelectric power, and a solar panel generates solar energy, none of which control heating/cooling.

Using public transport, carpooling, or biking reduces the number of individual cars on the road. Potholes are road defects, signs are for traffic guidance, and pedestrians are people walking, so these are not reduced by such transportation choices.

Answer:

D. A smart thermostat
