Question

question 6
which is the closest antonym for the word instrumental, as it is used in the article?
a. accidental
b. practical
c. continual
d. optional

Explanation:

When "instrumental" is used to mean serving as a crucial, intentional tool or factor for a result, its closest antonym is a word describing something unplanned or not intended for a purpose. "Accidental" means happening by chance, not intended, which is the opposite of the intentional, functional meaning of "instrumental". "Practical" is a synonym, "continual" refers to frequency, and "optional" refers to being non-mandatory, neither of which match the antonym requirement.

Answer:

A. accidental
