Question

the port of houston is one of the busiest ports in the country. the u.s. department of energy gave this port $3.4 million to operate twenty heavy - duty hydrogen hybrid fuel cell powered trucks around the port. which is the most likely reason the u.s. government made such an investment?
○ to produce more water
○ to improve fueling stations
○ to move more cargo
○ to reduce harmful emissions

Explanation:

Hydrogen hybrid fuel cell - powered trucks are known for being more environmentally friendly as they produce fewer harmful emissions compared to traditional fuel - powered trucks. Producing more water is not a typical goal of using such trucks. Improving fueling stations is not directly related to operating these specific trucks. While moving more cargo could be a secondary benefit, the primary environmental benefit of reducing emissions is a key reason for government investment in such clean - energy - based transportation solutions, especially from the Department of Energy which is concerned with energy and environmental impacts.

Answer:

D. to reduce harmful emissions (assuming the options are labeled A, B, C, D with D being "to reduce harmful emissions")
