Final answer:
The sample text includes both active and passive voice. The first paragraph uses active voice, while the second paragraph predominantly uses passive voice.
Step-by-step explanation:
The text contains both active and passive voice paragraph. The first paragraph uses active voice where the subjects (the professor, students) are performing the action (grading, scoring). For example, in 'The professor graded the essays', 'professor' is the subject doing the action of 'grading'. However, the second paragraph primarily uses passive voice where the subjects (the potholes, safe driving) are receiving the action (being repaired, appreciated). In 'The potholes are being repaired by the workers', 'potholes' is the subject of the sentence, but it's not doing the action but rather receiving it, which is a characteristic of passive voice.
