In the context of a city's energy grid, which verb best completes the sentence: 'The grid ___ the city'?

• A. drains
• B. disrupts
• C. powers
• D. transforms

Answer: (C)

The key idea is identifying a verb that captures what an energy grid does for a city. An energy grid provides the electricity that the city runs on, so the best choice is powers. Saying “The grid powers the city” directly expresses that the grid supplies the energy that enables lights, machines, transportation, and all city functions to operate.

Drains would imply the grid takes energy away from the city, which doesn’t fit the typical role. Disrupts suggests causing problems rather than providing energy, and transforms would mean changing the city itself rather than supplying power. A natural phrasing is The grid powers the city, a common way to describe infrastructure delivering energy.
