Choose “NO CHANGE”
In fact, the correct answer to a question is not necessarily
one that has changed anything at all. All Usage/Mechanics questions
and some Rhetorical Skills questions offer you “NO CHANGE” as an
answer choice. Do not overlook “NO CHANGE” as a possible answer to
the problem. It is correct approximately 20 percent of the time
If your gut tells you there’s nothing wrong with the underlined
phrase, don’t change the phrase.
