Yes, I agree with the response provided by
D33T. I would add that if you are quoting some source you are using to study English grammar, get yourself another source! That is a poorly phrased sentence, to say the least. One useful skill that you can develop when you look at
any sentence, though, is to identify a subject and its corresponding verb. By and large, when you see prepositions—words such as
in,
on,
over, and, perhaps the most tested,
of—you can cross off any words that follow until you hit a verb. Doing so will expose subject-verb agreement errors. Take the sentence you provided:
Quote:
The surest
way to achievement
in class tests and final exams ______________ perseverance.
The subject is
the way, and you should know that it is singular. (
Surest is simply modifying
way.) Although
tests and
exams are plural, they are both objects of the preposition
in (although a case could be made that
on is more fitting). As such, the shell of the sentence is nothing more than
The way to [something] ___ perseverance.It should be obvious that
are would be incorrect. Remember, no matter how convoluted a sentence may appear to be, it still needs to be built from a subject and a verb. The better you can get at identifying those two crucial elements, the better you will get at SC.
Good luck with your studies.
