Question

subject-verb agreement
subject - verb agreement means the subject and predicate in a sentence must agree in number.

• subject: who or what the sentence is about
• predicate: what the subject is doing (action)

singular
subject - does not end in \-s\
verb - ends in \-s\
plural
subject - ends in \-s\
verb - does not end in \-s\
multiple singular subjects
\and\ - plural verb form
\or\ - verb should agree with the nearest subject
exceptions:

• collective nouns: words that act as a singular noun while representing a group
• indefinite pronouns: pronouns that do not explicitly denote a number of subjects
• some singular subjects end in the word s but are not plural. (e.g. \politics\)

which sentence has correct subject - verb agreement?
james was jogging during sunset.
mark are jogging down the path.
mary were jogging for a hour.

Explanation:

• In "James was jogging during sunset", the subject "James" is singular. The verb "was" (past - tense form of "to be" for singular subjects) is in agreement.
• In "Mark are jogging down the path", the subject "Mark" is singular. The verb "are" is plural, so there is a subject - verb disagreement.
• In "Mary were jogging for a hour", the subject "Mary" is singular. The verb "were" is plural, so there is a subject - verb disagreement.

Answer:

James was jogging during sunset.
