write a sentence that uses a incorrect shift in voice. Then explain why the shift is incorrect. Then write a sentence that corrects the shift

Incorrect Shift: The cake was baked by Sarah, and then you cut it into slices.

Explanation: The first part of the sentence is in the passive voice, but the second part suddenly shifts to the active voice.
Corrected: The cake was baked by Sarah, and then it was cut into slices by you. (Both parts of the sentence are now in the passive voice, providing consistent syntax.)
