Question

Quizplus · Accepted Answer

When people see someone picking up litter and properly disposing of it, it sets a positive social norm and encourages them to follow suit. On the other hand, seeing litter all around (option A) or someone kicking litter (option C) may actually normalize and reinforce littering behavior. Option D may not have any significant impact on littering behavior as it is simply stating the presence of fliers without any other contextual information.
