Read the following paragraph and answer the question below:
“Our town has become a disgusting dump. The amount of garbage lying in ours our streets is truly upsetting. When I visited Athens, Greece I saw that they had special recycling bins that when you insert a can or bottle you get a nickel. I think we need to adopt this practice. The amount of litter in Athens has dropped 75% since putting in these bins, since the average person is now encouraged to pick up any bottles or cans he or she sees. If we put in these special bins, I believe we will see the same results. Let’s install these bins and trash our litter problem.”
