This document provides guidance on subject-verb agreement in sentences. It discusses several rules: 1) Ignore words separating the subject from the verb like "along with" and use the verb form matching the subject. 2) Use a singular verb for distances, times, sums considered as a unit. 3) Collective nouns like "group" can take a singular or plural verb depending on use. 4) A subject will precede a phrase beginning with "of". The document ends with an exercise applying these rules.
