Final answer:
The sentence 'Ella vas temprano a la tienda' is grammatically incorrect because the subject and verb do not agree.
Step-by-step explanation:
The sentence Ella vas temprano a la tienda is grammatically incorrect. The subject of the sentence, 'Ella' (which means 'she' in English), does not agree with the verb 'vas', which is used for the pronoun 'tú' (meaning 'you' in English). To make the sentence grammatically correct, we should use the verb 'va' instead, which is the correct form for the pronoun 'ella'.
