Which sentence demonstrates proper usage of subject-verb agreement?

To determine which sentence demonstrates proper usage of subject-verb agreement, we need to understand the basic rule of subject-verb agreement. In a sentence, the subject (a noun or pronoun) and the verb must agree in number. Singular subjects take singular verbs, and plural subjects take plural verbs.

Let's consider a few examples:

1. "The dog barks in the park." - This sentence demonstrates proper subject-verb agreement. The singular subject, "dog," is paired with the singular verb, "barks."

2. "The dogs bark in the park." - This sentence also shows proper subject-verb agreement. The plural subject, "dogs," is paired with the plural verb, "bark."

Now, comparing these examples, we can see that both sentences demonstrate proper subject-verb agreement. The choice between these sentences depends on whether the subject is singular or plural.

To determine if subject-verb agreement is demonstrated, simply identify the subject of the sentence and ensure that the verb agrees with it in terms of singular or plural form.
