Auto engineer: Hopeful researchers claim that one day cars will be powered by hydrogen, which will be extracted from water using renewable energy sources. It takes a tremendous amount of energy to extract hydrogen from water, though.
Considering the 700 million automobiles now in use, the goal of using renewable resources to obtain hydrogen to power them should be abandoned. We could generate enough energy to extract that amount of hydrogen with a massive deployment of nuclear power plants, but those require nonrenewable resources and are unpopular in many areas.
The auto engineer’s recommendation to abandon researchers’ goal of powering cars with hydrogen extracted using renewable energy is based on which of the following assumptions?

Researchers have misled the public into investing large amounts of money in the development of hydrogen cars
The inefficiency of hydrogen cars makes refueling them costly and unpopular
It would take many years for the 700 million automobiles currently in use to be replaced by hydrogen-powered vehicles
The unpopularity of nuclear power plants makes it unlikely that sufficient nuclear power could be obtained to extract the hydrogen necessary for powering the number of automobiles currently in use
No renewable energy sources could provide the power necessary to create sufficient fuel for the number of automobiles currently in use
