Answer:
<u>Three</u> nouns: pencils, paper, books.
Explanation:
A noun is a word that names a thing, a person, animal, place, idea, feeling, quality, phenomenon, substance, etc., in other words, it is a word that names something or someone.
In the sentence, <em>pencils, paper </em>and<em> books</em> are all nouns because they name things. The other words, on the other hand, are not nouns: <em>she</em> is a pronoun (a substitute of a noun), <em>brought</em> is a verb, <em>and</em> is a conjunction, <em>with</em> is a preposition and <em>her</em> another pronoun.
