Question

Identify the italicized word according to its class in structural linguistics. The principal is extremely busy.

Answer 1

The italicized word is extremely and the correct answer is intensive.
The word extremely is an adverb, which means that you can rule out noun, adjective, and verb immediately. You can also rule out empty word because extremely has a particular meaning on its own, which means that it cannot be empty. Thus, we are left with one option only - intensive.
