Here's why:
* "Pass" is a verb, but in this case, it's missing a helping verb (like "does" or "will") to make it a complete verb phrase.
* "She" is a pronoun, acting as the subject of the sentence.
To make a grammatically correct sentence, you would need to add a helping verb:
* She passes (present tense)
* She passed (past tense)
* She will pass (future tense)
