The correct sentence demonstrating proper subject-verb agreement is:
"Most of the school attends the pep rally."
However, there is a typo in this option because "attends" should be used with a singular noun, and “school” is treated as a singular collective noun in this context.
So, the corrected sentence should use "attend" for "most of the school" as well.
The correct sentence should be:
"Most of the school attend the pep rally."
Let's go through the incorrect ones as well:
- "Most of the teachers attends the pep rally." - Incorrect. It should be "attend" since "teachers" is plural.
- "Most of the students attends the pep rally." - Incorrect. It should be "attend" since "students" is plural.
- "Most of the attends the pep rally." - This sentence is incomplete; "the" should specify what noun it refers to, making it incorrect.
So the most correct option, then with modifications, is: "Most of the school attend the pep rally."
