Difficulty: EasyBridging Gap (Supporter) Assumptions

Match each argument (stimulus) with the supporter assumption that is necessary to bridge the logical gap between its premise and its conclusion.

  • The proposed community center will feature state-of-the-art recreational facilities. Therefore, the proposed community center will improve the overall health of the neighborhood.Any facility that features state-of-the-art recreational facilities improves the overall health of its surrounding neighborhood.
  • The author's latest book employs a highly unconventional narrative structure. Thus, the author's latest book will be praised by literary critics.Literary critics generally praise books that employ highly unconventional narrative structures.
  • The new manufacturing process reduces the use of synthetic chemicals by half. Consequently, the new manufacturing process is better for the local environment.Reducing the use of synthetic chemicals in a manufacturing process is better for the local environment.
  • The company's customer service hotline is now available 24 hours a day. As a result, the company's customer retention rate will significantly increase.Making a customer service hotline available 24 hours a day leads to a significant increase in customer retention rates.

Answer

Pair the community center argument with the health assumption, the author's book argument with the literary critics assumption, the manufacturing process argument with the environment assumption, and the hotline argument with the retention assumption.
In each case, the correct assumption functions as a required bridge that connects the new 'rogue' term in the conclusion back to the evidence provided in the premise. Without these bridges, the conclusions remain completely unsupported.

Step-by-Step Solution

1
Identify the premise and the conclusion in each argument.
Each argument contains a premise (evidence) and a conclusion that introduces a new, unstated concept known as the 'rogue' element.
Finding the new concept in the conclusion is the first step in identifying a missing supporter assumption.
2
Determine the exact logical gap for each argument.
The gaps are: recreational facilities to health, unconventional structure to critic praise, fewer synthetic chemicals to better environment, and 24-hour hotline to higher retention.
A supporter assumption must explicitly connect the evidence in the premise to the new claim in the conclusion.
3
Select the assumption that links the premise concept directly to the conclusion concept.
The matching assumptions form direct 'If Premise, then Conclusion' bridges.
This completes the logical structure, validating each argument.
