Question

Difficulty: HardNecessary vs. Sufficient Condition Flaws

Political Scientist: A thriving democracy cannot exist without a highly educated electorate. Critics of the proposed national curriculum argue that its heavy emphasis on critical thinking and media literacy is a waste of resources. But this curriculum will undeniably result in a highly educated electorate. Therefore, the adoption of this curriculum will inevitably result in a thriving democracy.

Which of the following most accurately describes a flaw in the political scientist's reasoning?

  1. A
    takes for granted that because a societal change historically preceded democratic stability, the change must have caused that stability
  2. B
    fails to recognize that the phrase 'thriving democracy' is used in two distinctly different senses within the argument
  3. C
    takes the failure to satisfy a sufficient condition as proof that a necessary condition will not be satisfied
  4. D
    assumes that an educational curriculum beneficial for individual citizens will be equally beneficial for the nation as a whole
  5. infers the occurrence of a phenomenon solely from the presence of a precondition without which that phenomenon could not occurAnswer

Answer

The argument infers the occurrence of a phenomenon solely from the presence of a precondition without which that phenomenon could not occur.
The correct answer accurately describes an illegal reversal in abstract terms. The argument states that a highly educated electorate is required (a necessary precondition) for a thriving democracy. It then establishes that the curriculum will produce a highly educated electorate, and concludes this alone is enough to guarantee (infer the occurrence of) a thriving democracy. This illicitly treats a necessary condition as if it were a sufficient condition.

Step-by-Step Solution

1
Analyze the first sentence to identify the primary conditional relationship.
A thriving democracy requires a highly educated electorate (Thriving Democracy -> Highly Educated Electorate).
The phrase 'cannot exist without' introduces a necessary condition, making a highly educated electorate the precondition.
2
Analyze the remaining premises to identify the secondary relationship.
The proposed curriculum guarantees a highly educated electorate (Curriculum -> Highly Educated Electorate).
The scientist explicitly states the curriculum will 'undeniably result in' this outcome.
3
Identify the argument's final conclusion.
The argument concludes that the curriculum guarantees a thriving democracy (Curriculum -> Thriving Democracy).
This is indicated by the transition phrase 'Therefore, the adoption of this curriculum will inevitably result in'.
4
Compare the premises to the conclusion to identify the logical gap.
The argument assumes that because the curriculum leads to a highly educated electorate, it must automatically lead to a thriving democracy.
This logic incorrectly assumes that a highly educated electorate is sufficient for a thriving democracy (Highly Educated Electorate -> Thriving Democracy), which is an illegal reversal of the first premise.
