The sentence "The bike on the bike rack is blue." is correct.

The correct sentence is: "The bike on the bike rack is blue."

To determine which sentence is correct, let's analyze each one:

1. "The bike on the bike rack is blue."

- This sentence is grammatically correct. It follows the subject-verb agreement, and the singular noun "bike" matches with the singular verb "is." Moreover, it states a coherent statement that can be true or false.

2. "The surface of the parking lots were redone this summer."

- This sentence contains an error in subject-verb agreement. "Surface" is singular, so the verb "were" should be "was" to match the singular subject. The correct sentence would be: "The surface of the parking lots was redone this summer."

3. "The cars in the parking lot belongs to the teachers."

- This sentence has a subject-verb agreement error as well. "Cars" is plural, so the verb "belongs" should be changed to "belong" to match the plural subject. The correct sentence would be: "The cars in the parking lot belong to the teachers."

4. "The sidewalks in the courtyards has been decorated with chalk."

- This sentence also contains a subject-verb agreement error. "Sidewalks" is plural, so the auxiliary verb "has" should be changed to "have" to match the plural subject. The correct sentence would be: "The sidewalks in the courtyards have been decorated with chalk."

Based on this analysis, the correct sentence is: "The bike on the bike rack is blue."
