Situation: In the island nation of Bezun, the government taxes gasoline heavily in order to induce people not to drive.
Situation
Bezun heavily taxes gasoline to discourage driving (objective 1) and uses the revenue to subsidize electricity and reduce its price (objective 2).
Analysis
The greater the success at objective 1, the less success at objective 2.
Evaluate
The more we discourage driving, the less gasoline tax we'll collect, so we'll have less revenue to subsidize electricity costs.
Goal
Find the answer with the same logic that the better you do at your first goal, the less well you'll do at your second goal.
