Answer:
C
Step-by-step explanation:
This is by process of elimination. A is already out, this has nothing to do with plastic bags. B looks interesting at first glance, but it talks about just the city, recycling from one city can't make the world a better place. C looks good. D also looks good. So I had to think which one would be better, so I looked though the text and D says "if they are recycled" and the text says, "Offer to purchase aluminum cans for recycling". Option D also says that it can be used for a variety of purposes but does not actually state the purposes aluminum cans can be used for. So I went with C, take this with a grain of salt as I have only had 3hrs of sleep.
