Answer
Brief Explanations:
The passive voice is used when the focus is on the action rather than the doer. In the sentence "When we can pick our reading, mythology is most often chosen in my class", the main verb "is chosen" is in the passive voice. The subject "mythology" is receiving the action of being chosen.
