Adjective, adverb and noun

Explanation:

A clause is a group of words that at least have a subject and a verb, and that may be independent (It can stand by itself) or independent (It cannot stand by itself because it does not have full meaning). Dependent clauses may have one of the following three grammatical functions: Adjective, adverb, or noun.

. a function is a relation in which each input has only one output. in the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

i say that the right answer is: three personal subject pronouns. that’s because you will see “she” two times, referring to the librarian, and “they” one time, referring to the books. personal subject pronouns are used to replace common nouns or proper names.

the only possessive noun it’s present on the first sentence, when the speaker refers to “his” father.
