Answer:
D. Some cartmen helped others haul their belongings for little to no pay.
Step-by-step explanation:
Remember, after the narrator had stated that some cartmen demanded up to $150 for carrying a single load, the narrator stated, "some cartmen worked for whatever the sufferers felt able to pay."
Indeed, cartmen are ordinary people, and to act heroically also involves showing human sympathy. Thus, since some cartmen helped others haul their belongings for little to no pay, it becomes evident that ordinary people can act heroically in difficult times.
