Paper and plastic grocery bags are a continuing problem for the city, both as litter and in landfills. To discourage their use, the city has proposed a tax on each bag, to be paid by the supermarkets that supply them. Several environmental groups, however, oppose the tax, despite having brought the issue to the council' s attention in the first place. Which of the following, if true, would best explain the environmental groups' opposition to the proposed tax?
A: Only supermarkets distributing more than a certain number of grocery bags each month would be subject to the proposed tax.
B: Plastic bags account for 90 percent of the grocery bags that litter the city's streets and take up space in landfills.
C: The cost to the city of collecting and disposing of a grocery bag is greater than the proposed tax per bag.
D: Supermarkets plan to pass the tax on to consumers, who are unlikely to change their behavior based on the small increase in their grocery bills.
Choose A, B, C or D as your solution.
