Which sentence uses correct subject-verb agreement?

• My teachers often gives homework on the weekend.
• My brother always want to cook dinner.
• The clouds swiftly moves across the sky.
The cat carefully steps across the fence.

The correct sentence that uses subject-verb agreement is: The cat carefully steps across the fence.

The correct answer is:

• They are both singular or both plural.

When subjects and verbs agree, it means that they both have the same number, either singular or plural. For example, if the subject is singular, the verb should also be singular, and if the subject is plural, the verb should also be plural. This ensures grammatical correctness and agreement within a sentence.

Out of the options provided, the first choice, "They are both singular or both plural," most accurately describes subject-verb agreement. When subjects and verbs agree, it means that they match in terms of their number. In other words, if the subject is singular, the verb should be singular, and if the subject is plural, the verb should be plural as well.

To determine subject-verb agreement, here's a step-by-step guide:

1. Identify the subject: Find the noun or pronoun in the sentence that the verb is referring to. The subject is usually the person, thing, or idea that is performing the action or being described.

2. Determine the number: Check if the subject is singular (referring to one person or thing) or plural (referring to more than one person or thing).

3. Make the verb agree: If the subject is singular, the verb should also be in singular form. For example: "He runs," where the subject "he" is singular, and the verb "runs" agrees with it. Similarly, if the subject is plural, the verb should be in plural form. For example: "They run," where the subject "they" is plural, and the verb "run" agrees with it.

It is crucial to note that subject-verb agreement should remain consistent even when using pronouns. For instance, if the subject is the singular pronoun "he," the verb should still be in singular form, such as "he plays." Conversely, if the subject is the plural pronoun "they," the verb should be in plural form, such as "they play."

Regarding the other options described in your question, "They describe the same things" and "They have the same ending," these do not accurately define subject-verb agreement. Additionally, the statement "They are not separated by interrupting words" is not directly related to subject-verb agreement but rather focuses on the avoidance of placing interrupting words between the subject and verb in a sentence to maintain clarity.
