Explanation:
A noun phrase is a phrase acting as a subject, a direct or indirect object or an object of a preposition, that contains a noun or pronoun (also called the head), and that may contain modifiers of that head, like articles (e.g. <em>the, a/an</em>), quantifiers (e.g. <em>a lot</em>), determiners (e.g. <em>those</em>), numbers (e.g. <em>one, two...</em>) and adjectives. A phrase noun, then, does not express a complete thought on its own and does not contain verbs.
“The prices will also vary” is not a noun phrase because it has a verb “will...vary.” The phrase “the prices,” instead, is a noun phrase.
“Two of the biggest factors,” on the other hand, is a noun phrase that acts as the subject of the sentence because it has a noun, which it's <em>factors</em> (also the head), and modifiers of that head: <em>two</em> (a number), <em>of</em> (a preposition), <em>the</em> (an article) and <em>biggest</em> (an adjective).
“for the services they provide.” is not a noun phrase because it has a verb: <em>provide</em>, and does not act as a noun.
Similarly, “will still be a wide price range” is not a noun phrase because it has a verb phrase: <em>will... be</em>.
The impact Mama's decision to give the quilts to Maggie has on the development of the plot of "Everyday Use" is the Dee wants to keep the quilts to appreciate for "her heritage" but Maggie wants to use it as its purpose. This led to Dee believing that Maggie can’t appreciate the quilts just as how she sees them, and she thought that the quilt will be put to “everyday use” by Maggie and within 5 years or so, the quilt will turn into a rag.
