Answer:
Intensive
Explanation:
The options you were given are the following:
- intensive
- adjective
- noun
- empty word
- verb
The italicized word is <em>extremely</em>. It is an adverb. Adverbs are words used to modify verbs, adjectives, and other adverbs. Here, <em>extremely </em>modifies the adjective <em>busy</em>. This is why we can eliminate <em>noun, adjective, </em>and <em>verb</em> as potentially correct options.
Empty words are words that have no lexical meaning and function as a grammatical link or marker. An example of an empty word in English is the infinitive marker <em>to</em>.
Intensives are words used to show stronger, more forceful, or more concentrated actions. An example of an intensive used in English is <em>so</em>. Here, the word <em>extremely </em>intensifies the principal's busy-ness.
