Urban Planner: Over the past three decades, the city's targeted tax incentives for tech companies have consistently stimulated job growth and successfully driven down the local unemployment rate. The city council has just approved a new round of identical tax incentives for tech startups. Therefore, we can confidently expect the local unemployment rate to fall over the next two years.
Which of the following identifies the most serious flaw in the urban planner's reasoning?
- Afails to consider that the historical relationship between the incentives and unemployment was merely coincidental rather than causal
- Btreats a policy implementation that may be sufficient to reduce unemployment as though it were the only way to achieve that reduction
- Cillegitimately infers a decrease in the total number of unemployed residents from a decrease in a proportional rate
- bases a prediction about a future outcome on a past pattern without establishing that the conditions enabling that pattern remain in placeAnswer
- Erelies on an ambiguous interpretation of the phrase 'tax incentives' to connect the historical data with the current proposal
Answer
The correct answer identifies that the argument draws a conclusion about a future outcome based on a past pattern without verifying that underlying conditions remain unchanged.
The argument relies entirely on the premise that a specific policy was successful over the past thirty years. It then leaps to the conclusion that an identical policy will be successful over the next two years. This reasoning is flawed because it fails to consider whether the surrounding circumstances—such as the overall health of the tech industry, the availability of skilled labor, or broader economic trends—have remained static enough for the historical pattern to reliably repeat itself.
