Answer:
1. B) clothes.
2. D) Place the refuse 'down' the garbage chute.
Step-by-step explanation:
1. B) An antecedent is a word or words that a pronoun refers to. In the sentence, the demonstrative pronoun "those" (which is plural) is referring to the word "clothes" (plural as well)
2. D) Prepositions are a type of word that is usually placed in front of nouns or pronouns to show the relationship between the noun or pronoun and other words in a sentence. The sentence "Place the refuse 'down' the garbage chute." uses "down" as a preposition because it is placed in front of the noun "the garbage chute". In sentence number 1, "down" does not work as a preposition (it is not placed in front of a noun) but as an adverb, as it indicates "where" the prices go (it modifies the verb "go").
