Final answer:
The word 'screen' is the only noun in the sentence that is NOT a noun.
Step-by-step explanation:
In the sentence 'He brought his computer to the repair store to have his cracked screen fixed', the word 'screen' is the only noun in the sentence that is NOT a noun. 'He,' 'store,' and 'computer' are all nouns because they are naming words that refer to people, places, or things. However, 'screen' is used as a verb in this sentence to describe an action, which means it is being used as a verb, not a noun.
