Verb-ed modifier
The U.S. Energy Department has already begun its much-awaited and well-planned endeavor to illuminate the remote villages of its states and the world, a project supported by government labs, private companies, and investors and consisted of hundreds of wind and solar energy systems.
A) consisted
B) will consist
C) consisting
D) is consisting
E) are consisting
I couldn’t understand why C is correct here.
you need something to be parallel to “supported” — a modifier to “a project”.
If you look closely, “consisted” is a verb, not a modifier. Only “consisting” works.
In parallelism, similar things should be placed in parallel. They need not necessarily have the same structure.
