Which statement about plug-in hybrids relative to all-electric travel is true?

• A. They cannot be charged
• B. They require hydrogen
• C. They have larger battery packs enabling all-electric travel
• D. They rely solely on gasoline

Answer: (C)

The key idea is how plug-in hybrids compare to all-electric travel in terms of battery size and electric driving capability. Plug-in hybrids carry a larger battery that can be charged from the grid, which lets them run on electricity for a portion of the trip. That electric range means you can do all-electric travel for part of the journey, with the gasoline engine kicking in when the battery runs low. All-electric vehicles, by contrast, run solely on battery power for every mile. This explains why having a larger battery enables all-electric travel in plug-in hybrids. Hydrogen isn’t required, and they don’t rely exclusively on gasoline.
