In the following question a sentence is given with a

Solution

Explanation: The word "establish" fits best in this context as it conveys the idea of setting up or creating new classrooms to address overcrowding. "Build" could also work, but "establish" is more formal and appropriate in the context of administrative or legal language, where "setting up" or "creating" is more commonly used. "Form" and "creation" are less suitable here, as "form" implies a more abstract concept, and "creation" would require a different grammatical structure (e.g., "the creation of new classrooms").
