Difficulty: HardFalse Dilemma (False Dichotomy)

Mayor: Our municipality is facing a critical energy shortage and must rapidly increase its power generation capacity. Critics oppose the construction of a new nuclear power facility, citing safety concerns and the high cost of waste disposal. However, if we do not construct the nuclear facility, we will be forced to rely exclusively on imported fossil fuels, which will drastically increase our greenhouse gas emissions and violate our climate commitments. Therefore, the critics are wrong, and we must proceed with the nuclear facility.

Which of the following most accurately describes a logical flaw in the mayor's argument?

  1. It overlooks the possibility that the municipality could increase its power generation capacity using alternative energy sources other than a nuclear facility or imported fossil fuels.Answer
  2. B
    It shifts the meaning of the term "capacity" from the total amount of energy that can be generated to the efficiency with which that energy is distributed over the grid.
  3. C
    It rejects the critics' safety concerns without providing any scientific evidence demonstrating that modern nuclear facilities are entirely safe to operate.
  4. D
    It presumes that because relying exclusively on fossil fuels guarantees a violation of climate commitments, avoiding fossil fuels is logically sufficient to ensure those commitments are met.
  5. E
    It mistakes a condition that is required to meet the municipality's environmental commitments for one that will independently ensure the energy shortage is fully resolved.

Answer

The correct answer is the option stating that the argument overlooks the possibility of using alternative energy sources other than a nuclear facility or imported fossil fuels.
The argument is fundamentally flawed because it presents exactly two mutually exclusive and exhaustive options for solving the energy shortage: building a nuclear facility or relying exclusively on imported fossil fuels. By failing to consider middle-ground or alternative possibilities—such as solar, wind, geothermal energy, or conservation efforts—the argument rests on a false dichotomy.

Step-by-Step Solution

1
Identify the argument's main conclusion.
The conclusion is: 'We must proceed with the nuclear facility.'
This is the primary claim the mayor is trying to prove against the critics.
2
Identify the premises provided to support the conclusion.
Premise 1: The city must increase power capacity. Premise 2: If the nuclear facility is not built, the city will be forced to rely exclusively on fossil fuels. Premise 3: Relying on fossil fuels violates climate commitments.
Understanding the structure helps isolate the gap between the evidence and the conclusion.
3
Evaluate the logical jump between the premises and the conclusion.
The argument assumes a strict either/or scenario: either build the nuclear plant OR rely 100% on fossil fuels.
The conclusion only logically follows if there are absolutely no other ways to generate power.
4
Select the option that describes this specific vulnerability.
The correct choice identifies that the mayor fails to consider other clean energy alternatives, thereby committing a false dilemma.
Flaw questions require describing the specific structural error made by the author.
