Answer:
Every Monday, students in Mrs. Verdan's class work with partners to complete math challenges. Each pair selects its own work space. Jermey and Melvin go to the math center. Gregory and Leo like the sunny table by the window. Hector and Jeff choose chairs near the board. Lily and Masandra take the round table near the door. Manny and Zoe grab the soft seats in the library corner. All of the pairs have 45 minutes to solve the day's puzzle. They share their solutions with the whole group. A few students meet with Mrs. Verdan after school. She explains the solutions and answers questions. Mrs. Verdan's students always enjoy the weekly math challenges.
Explanation:
A subject and a verb must agree in the sense that, if the subject is singular, the verb must also be singular. If it is plural, the verb must also be plural. In the passage we are to correct here, the subject-verb agreement has not been respected. Let's select a couple of examples from the passage to better illustrate it:
1. "students in Mrs. Verdan's class works" --> "works" ends in -s, which indicates it is a third-person singular verb. However, the subject of the sentence is "students", not "Mrs. Verdan". "Students" is a plural noun that can be replaced with "they". "They works" is incorrect. Therefore, we should use "work".
2. "each pair select" --> "select" is a plural verb, but the subject "each pair" is single. As a matter of fact, it is always good to pay attention to the word "each", because it should always be followed by a singular verb. The correct form for the verb here is "selects".
