Answer:
2. The Middle School is conveniently located in the center of town.
Step-by-step explanation:
Only the first word of the sentence is correctly capitalized in sentences 1 and 3, no other terms should be capitalized in those sentences.
Besides the first word, the "American Medical Association" is correctly capitalized in sentence 4 since it is an acronym (AMA).
In sentence 2, "Middle School" is incorrectly capitalized; this term should only be capitalized when referring to a specific middle school.
