I think option D is correct, this was tricky!
the two elements of the paradox are that bottle deposit programs are incentivize recycling and other one is that states with comprehensive recycling program without bottle deposit, but are more successful
we don't quite what the definition of success is but it probably has something to with the environmental/financial aspect
The correct answer will help explain what makes comprehensive recycling more successful - thinking logically this is either due to money or overall compliance with program
A. Bottle deposit programs are less convenient for consumers and increasingly unpopular in state legislatures X
irrelevant, this only refers to disadv of bottle deposit, what about comprehensive recycling?
B. The level of motivation for individual consumers to recycle materials other than beverage containers remains the same regardless of which program is used. X
if motivation is same then this strengthens the paradox does not resolve it
C. Individuals have a greater financial incentive to actively recycle beverage cans and bottles if a bottle deposit program is in effect. X
this goes against the first element of paradox and does not resolve it
D. Aluminum cans have so much value that when these cans are included in the comprehensive program, instead of recycled separately, they pay for costs of the entire comprehensive recycling program. CORRECT
success=$$$ if the comprehensive program is self sufficient then this explains it success over the bottle program
E. There are more states with bottle-deposit programs than with comprehensive recycling programs. X
irrelevant! its not about no. of states
hope this helps
