I have to circle the simple subject,find the verb,decide if its right and if not I have to put the correct verb in its place. (subject-verb agreement) Across the grasslands sound the roar of the lions.

The simple subject is "roar," while "sound" is the verb. However, since "roar" is singular, "sounds" would be the correct form of the verb.

Although the arrangement is correct, it could also be "The roar of the lions sounds across the grasslands."

I hope this helps. Thanks for asking.

To identify the simple subject and verb in the sentence and determine if they agree or need correction, follow these steps:

1. Identify the subject: The subject of a sentence is the noun or pronoun that the sentence is about. In this case, the subject is "the roar."

2. Circle the simple subject: In this sentence, the simple subject is "roar." Circle the word "roar."

3. Identify the verb: The verb is the action or state of being in the sentence. In this case, the verb is "sound."

4. Determine subject-verb agreement: Subject-verb agreement means that the subject and verb must agree in number. If the subject is singular, the verb should be singular as well. If the subject is plural, the verb should be plural.

In the given sentence, the subject "roar" is singular, and the verb "sound" is also singular. Therefore, the subject and verb agree correctly.

No correction is needed in this sentence. The verb "sound" is suitable for the singular subject "roar."
