Difficulty: Very hardBridging Conflicting Premises

Over the past five years, the average temperature of the surface waters in the Coral Gulf has risen significantly. Nevertheless, marine biologists have documented that a specific species of thermal-sensitive algae—which thrives exclusively in cooler waters and perishes rapidly when exposed to warmer temperatures—has expanded its habitat significantly closer to the surface of the Coral Gulf during this exact same period.

Determine whether the following statement is true or false:
The additional premise that 'the warming of the surface waters in the Coral Gulf has completely eliminated a surface-dwelling predatory fish that previously served as the primary consumer of this thermal-sensitive algae' successfully resolves the apparent discrepancy presented above.

Answer: Answer

Answer

False
The proposed premise fails to resolve the paradox because it only addresses the ecological dynamic of predation while ignoring the absolute physical constraint established in the stimulus. Because the stimulus explicitly states that the algae perish rapidly in warmer temperatures, merely removing a predator does not explain how the algae survive the lethal warming of the surface waters. A successful resolution must bridge both conflicting facts.

Step-by-Step Solution

1
Identify the two conflicting premises in the stimulus.
Premise 1: Surface waters have warmed. Premise 2: Algae that perish in warmer waters have expanded closer to the surface.
Resolving a paradox requires a clear understanding of the two facts that appear to contradict each other.
2
Determine the criteria for successfully bridging the conflict.
A successful resolution must explain how the algae are able to survive closer to the surface despite the lethal warmer temperatures.
An effective bridging premise must allow both original premises to coexist logically without dismissing either.
3
Evaluate the proposed additional premise.
The proposed premise states that a predator of the algae has been eliminated by the warmer waters.
We must test if this new information satisfies the criteria established in Step 2.
4
Determine if the proposed premise successfully resolves the paradox.
It does not. While the lack of predators explains a potential reason for expansion, it fails to explain how the algae survive the lethal warmer temperatures.
A premise that resolves only one side of a paradox while ignoring an absolute constraint does not effectively bridge the conflicting premises.

Key Concept

Evaluating whether an additional premise successfully bridges a logical conflict without violating established constraints.
