Answer:
c. Produce inconsistent choices
Step-by-step explanation:
We can try to understand this in a mathematical way. If A is higher than B, and B is higher than C, then A should be higher than C. In other words, the school should have higher preference than the dam, and the dam has higher preference than the road, then the school should have higher preference than the road.
Since this is not the result here, we must conclude that the choices are inconsistent.
