the principal objective of our booster club is to raise money for new marching band uniforms
which definition best helps readers find the correct meaning of principal in this sentence?
first, highest in rank or importance
the head of a school or organization
a sum of money
a rule of action or conduct

Explanation:

In the sentence "The principal objective of our booster club is to raise money for new marching band uniforms", "objective" means goal. "Principal" here describes the objective. Looking at the definitions: "first, highest in rank or importance" (adjective) fits as it can describe an objective (as in the main/most important goal). "The head of a school..." is a noun (for a person). "A sum of money" is a noun (for money). "A rule..." is for "principle" (different word).

Answer:

first, highest in rank or importance
