Answer:
The sentence which demonstrates correct subject-verb agreement is:
C. Where are the watering cans stored?
Explanation:
If the subject of a sentence is singular, the verb must agree with it by being conjugated in its singular form. If the subject is plural, the verb must also be plural.
All the options given use forms of the verb to be. "Is" is used for the third person singular, while "are" is used for plural. To find the subject of each sentence, we must ask the verb a question - who or what.
A. Where is the plants growing? - What is what growing? The plants. plants = plural, is = singular. This sentence is INCORRECT.
B. Where are the hookup for the hose? - Where are what? The hookup. hookup = singular, are = plural. Again, INCORRECT
C. Where are the watering cans stored? - Where are what stored? The watering cans. cans = plural, are = plural. This is CORRECT.
D. Where is the students going to weed? - Where is who going to weed? The students. students = plural, is = singular. INCORRECT
