Situation: In the island nation of Bezun, the government taxes gasoline heavily in order to induce people not to drive. It uses the revenue from the gasoline tax to reduce prices charged for electricity.
Analysis: The greater the success achieved in meeting the first of these objectives, the less will be the meeting the second.
What this question is testing
Situation
Bezun has a clever-sounding plan: heavily tax gas to make people drive less, and use that gas-tax money to subsidize electricity. Two birds, one stone.
Analysis
But there is a catch. The more successful the gas tax is at making people drive less, the less gas-tax revenue comes in — and so the less money there is to subsidize electricity. Success at the first goal undermines the second.
Evaluate
The pattern is: a tax that discourages activity A (drivers buying gas) funds a program for goal B (cheap electricity). The two goals are wired against each other — the more A drops, the less money for B.
Imagine a soda tax used to fund nutrition education: the better the soda tax works at stopping soda buying, the less money there is for the education program. Same trap.
Goal
Find the answer where a fee is used to discourage an activity, and the revenue from that fee is used to fund a secondary goal — making success at deterrence cut into the secondary goal's funding.
