Question

read the sentence.

algebra is a precursor for calculus because it will help students to be successful in the latter course.

which word is closest in meaning to the underlined word?

○ complex training
○ preceding requirement
○ brief introduction
○ predominant trait

Explanation:

The word "precursor" refers to something that comes before and is a necessary preparation for something else. In the context, algebra is a prior required course for calculus. "Preceding requirement" matches this meaning, as it is a necessary course that comes before calculus. The other options do not fit: "complex training" does not convey the prior/required nature, "brief introduction" is too weak (algebra is a full foundational course, not just an intro), and "predominant trait" is unrelated to academic courses.

Answer:

preceding requirement
