Question

read the sentence.
the students found the grammatical rules incredibly simple to understand and use.
which word does the underlined phrase modify?
○ students
○ found
○ rules
○ understand

Explanation:

To determine which word the underlined phrase "incredibly simple" modifies, we analyze the sentence structure. The phrase describes the quality of the "grammatical rules" (how the rules are, i.e., simple to understand and use). "Students" is the subject performing the action, "found" is the verb, and "understand" is part of the infinitive phrase. So "incredibly simple" modifies "rules".

Answer:

C. rules
