Directions: Reading Comprehension - read the following passage to answer the question below.

Recent advances in automotive technology have enabled designers and engineers to develop cars with increasingly better fuel efficiency and less environmental impact. Hybrid models, with gasoline-powered engines supplemented by an additional electric battery for improved efficiency, represented an initial foray into cleaner transportation. Electric cars, the next generation in this paradigm, have dispensed with gas engines altogether, relying exclusively on electric motors. Eliminating internal combustion engines could cut fossil fuel consumption by a third and result in up to 45% fewer emissions of hazardous air pollutants. This change will necessitate a new infrastructure of charge stations, potentially replacing the gas station so iconic in 1960s U.S. car culture. In addition to reducing air pollution, electric cars can decrease noise pollution as well: Unlike their less technologically advanced counterparts, electric cars are virtually silent, although this benefit has the drawback of leaving pedestrians little warning of their approach.

The passage suggests that advances in automotive technology have culminated in which of the following results?

Select all that apply.


One-third less environmental impact


Changes in battery development


Understanding of clean transportation
