Question

Difficulty: MediumStatement and Assumptions

Read the policy intervention below designed to address urban congestion, and identify the unstated premises required for this policy to function as intended.

Policy Statement:
"To reduce traffic congestion during peak morning hours, the city administration will offer a 50% property tax rebate to corporate offices that shift their daily operational start time to 11:00 AM."

Which of the following assumptions are implicit in the administrative statement? (Select all that apply)

  1. A significant number of corporate offices currently have operational start times that overlap with peak morning traffic.Answer
  2. The financial incentive of a property tax rebate is substantial enough to motivate corporate offices to change their established schedules.Answer
  3. C
    Shifting corporate office start times to 11:00 AM will successfully eliminate all traffic jams in the city.
  4. D
    The city administration currently collects more property taxes from corporate offices than it requires for road maintenance.

Answer

The correct assumptions are that corporate offices currently contribute to peak morning traffic, and that the proposed tax rebate is a strong enough incentive to make them change their schedules.
The correct assumptions establish the necessary foundation for the policy. First, corporate offices must currently be contributing to the morning peak traffic; otherwise, changing their schedules would be pointless. Second, the proposed incentive (a 50% property tax rebate) must be perceived by the administration as substantial enough to actually motivate these offices to alter their established routines. Both are unstated premises required for the policy to be logical.

Step-by-Step Solution

1
Analyze the core objective and the proposed method in the statement.
The objective is to reduce morning traffic congestion. The method is incentivizing corporate offices with a tax rebate to start at 11:00 AM.
Identifying the goal and mechanism helps uncover what must be true for the plan to be viable.
2
Evaluate the first candidate assumption regarding current corporate schedules.
The assumption that corporate offices currently operate during peak hours is valid; if they did not, shifting their hours would not impact the congestion.
An assumption is an underlying premise necessary for the argument or policy to make sense.
3
Evaluate the second candidate assumption regarding the financial incentive.
The assumption that a 50% property tax rebate is a sufficient motivator is valid; without this premise, the administration would not have chosen it as the mechanism.
Policies offering incentives inherently assume the incentive is valuable enough to drive the desired behavioral change.
4
Evaluate the remaining candidate assumptions for logical fallacies.
The assumptions about eliminating all traffic or comparing tax collection amounts to road maintenance are rejected.
They represent extreme inferences or external factual claims rather than necessary implicit premises.
