Are #1 and #2 true of the Second Great Awakening? I think they are. It had its greatest effect in cities on the eastern seaboard. It was led...

I do not believe that you are right about #1 or #2 being
the right answer.  The best of these answers is actually #3.  The two that you mention
have some basis in truth, but are not really true.

The
Second Great Awakening did begin in New England, but its greatest impact was more in
rural areas.  For example, the best-known area that was affected was the "burned-over
district" in upstate New York.  It was led by people concerned about a decline in
religiosity, but they were not typically leaders from "old-line" churches like the ones
in #2.  Instead, the Awakening was led by individual preachers like Charles Grandison
Finney who were not leaders and who were not part of the more staid religious
sects.

#3 is correct because many of the reform movements
like abolition and temperance came out of this revival movement.  Finney himself, for
example, was an abolitionist.  The Second Great Awakening stressed the idea of human
perfectibility and this stress inspired people to try to perfect society as well as
individuals.
