Answer:
3. For his birthday, his friends would lavish him with many gifts.
Step-by-step explanation:
Context clues refer to the surrounding information of an unknown word that helps us infer the meaning of that word and how it is functioning in a sentence. By looking at the context clues, we can determine that options 1, 2 and 4 use “lavish” as adjectives because they modify the nouns next to them, while option 3 uses the word as a verb meaning “giving or using in large amounts” (the last definition given) because the word is placed next to the auxiliary verb “would,” it indicates the action that the subject “his friends” perform, and because of the use of the words “many” and “gifts.”
