Answer:
- If you go to a store in the United States to buy a garden hose, the prices will also vary, but the parts will probably come attached. - NOT a noun phrase
- Two of the biggest factors are sales taxes versus value-added taxes, and perceived value. - A noun phrase
- In the United States, states need to make money to help pay for the services they provide. - NOT a noun phrase
- There will still be a wide price range but all the prices – from the cheapest to the most expensive – will be much lower. - NOT a noun phrase
Step-by-step 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. the, a/an), quantifiers (e.g. a lot), determiners (e.g. those), numbers (e.g. one, two...) 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 factors (also the head), and modifiers of that head: two (a number), of (a preposition), the (an article) and biggest (an adjective).
- “for the services they provide.” is not a noun phrase because it has a verb: provide, 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: will... be.
