<em>Adjectives </em><em>are words that modify, identify, describe or give further information of nouns, and nouns are words that name things, persons, animals, places, ideas, among others. </em>
1. Argyles are patterned socks named after a Scottish clan
B. patterned
"Patterned" modifies and describes the noun "socks." The other options are incorrect because "Argyles" and "Socks" are nouns and "after" work as a conjunction in the sentence.
2. The furniture in the living room is very expensive
D. Expensive
Expensive modifies or describes the phrase noun "The furniture in the living room." "Very," on the other hand, is an adverb because its function is to modify the adjective "expensive."
3. A vase sat in the middle of the banquet table
C. Banquet
"Banquet" tells us which "table" the speaker is talking about, in other words, it gives us information about that noun, and therefore, it is the adjective.
