Final answer:
The imperfect form of the verb in the sentence is incorrect.
Step-by-step explanation:
The subject of the question is Spanish. The sentence 'El panadero tuvía que hacer pan en la noche' is incorrect. The correct imperfect form of the verb 'tener' (to have) in the sentence should be 'tenía'. So the correct sentence would be 'El panadero tenía que hacer pan en la noche' which means 'The baker had to make bread at night'.
