Final answer:
The sentences were reviewed for subject-verb agreement; two were correct and three required revisions to match the subjects with the appropriate verb forms.
Step-by-step explanation:
Subject-verb agreement is essential for correct English grammar. Let's evaluate each sentence:
C - The small, young puppy enjoys a game of fetch. (Correct)
I - Before class starts, Sara and Jenny likes to practice playing their violins together. (Incorrect; Correct version: Before class starts, Sara and Jenny like to practice playing their violins together.)
I - A small toddler in the preschool class refuse to take a nap after lunch. (Incorrect; Correct version: A small toddler in the preschool class refuses to take a nap after lunch.)
C - Each member on the debate team must participate in the final round. (Correct)
I - The flower bouquet smell wonderfully. (Incorrect; Correct version: The flower bouquet smells wonderfully.)
These examples show the importance of matching the subject, whether singular or plural, with the correct verb form to ensure subject-verb agreement.
