Difficulty: Very hardBridging Gap (Supporter) Assumptions

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

  • If a legal code prioritizes restorative justice over punitive measures, it requires a robust network of community mediators. The nation of Oakhaven lacks the funding necessary to train or employ community mediators. Therefore, Oakhaven's legal code will inevitably fail to lower the national recidivism rate.A legal code that cannot prioritize restorative justice over punitive measures is destined to fail at lowering the recidivism rate.
  • A dietary supplement can only be marketed as "performance-enhancing" if clinical trials demonstrate a significant increase in muscular endurance without elevating resting heart rate. The novel compound XT-4 increases endurance by 15%, but trials show it elevates the resting heart rate of users. Thus, XT-4 cannot be patented.No dietary supplement can secure a patent unless it qualifies to be marketed as performance-enhancing.
  • In the genre of abstract expressionism, a painting's artistic merit is determined exclusively by the emotional resonance of its chaotic forms. Sorel's latest canvas exhibits immaculate brushwork but fails to evoke any visceral reaction from its audience. Clearly, Sorel's canvas will not be inducted into the modern art museum's permanent collection.The modern art museum only inducts abstract expressionist paintings into its permanent collection if they demonstrate substantial artistic merit.
  • Societal stability requires a populace that explicitly trusts its governing institutions. Frequent political scandals predictably erode this trust by portraying leaders as self-serving. Since the current administration has been plagued by continuous scandals, the national economy is destined to enter a severe recession.A loss of societal stability inevitably triggers a severe recession within the national economy.

Answer

Connect each argument to the assumption that explicitly links the orphaned concept in the conclusion back to the logical chain established in the premises.
Each correct pairing successfully identifies the unstated premise required to make the argument's conclusion logically follow. In supporter assumption questions, the conclusion always introduces a new concept that did not appear in the premises. The correct assumption must explicitly link this new conclusion concept to the concepts established in the premises, effectively 'closing the gap' in the author's reasoning.

Step-by-Step Solution

1
Isolate the conclusion and the premises for each argument.
Identified the final claim and the supporting evidence for all four stimuli.
Structural breakdown is required to spot the exact point where the argument skips a logical step.
2
Identify the 'rogue' or 'orphaned' term in each conclusion.
Found 'fail to lower recidivism' (Argument 1), 'cannot be patented' (Argument 2), 'inducted into permanent collection' (Argument 3), and 'severe recession' (Argument 4).
A valid supporter assumption must mention the new concept introduced in the conclusion.
3
Identify the final proven point in each premise chain.
Found 'cannot prioritize restorative justice' (1), 'cannot be marketed as performance-enhancing' (2), 'lacks artistic merit' (3), and 'loss of societal stability' (4).
The assumption must connect the rogue conclusion term specifically to the end of the premise chain.
4
Match the argument to the assumption that correctly links the two elements using proper conditional or causal direction.
Successfully paired all four arguments with their corresponding linking assumptions.
Verifying the conditional direction (e.g., ensuring a necessary condition is mapped correctly) confirms the assumption validates the argument.
