Dear
chesstitans,
I'm happy to respond.
This is basically a good SC question. It has a clever double-layered parallel split:
. . .
a project = noun, appositive phrase
outside parallelism, branch #1supported by (inside parallelism)
\\
government labs,
\\
private companies,
and = conjunction linking the three branches of the inside parallelism
\\
investors and = conjunction linking the two branches of the outside parallelism
outside parallelism, branch #2________ of hundreds of wind and solar energy systemsThe first branch of the parallelism begins with a
participle, a noun modifier, "
supported." The second branch also needs to begin with a participle. We need the present active participle, "
consisting." OA =
(C) Remember that the present participle is an active participle (e.g. "
supporting") and the past participle is a passive participle ("
supported"). The verb "
consist" doesn't even have a passive form, so it doesn't have a past participle at all.
The two participle have different tense, but this is not a problem at all for parallel. Even full verbs in parallel can have different tenses. See
GMAT Grammar Rules: Parallelism and Verb TensesDoes all this make sense?
