Difficulty: HardResolve the Paradox

Scenario: A geothermal power facility instituted a flash-crystallization process designed to prevent amorphous silica scaling in its deep reinjection wells by precipitating dissolved silica into microscopic, suspended particles before the spent geothermal brine enters the injection boreholes. Pipeline flow tests verified that these suspended micro-particles do not adhere to interior pipe surfaces. Nevertheless, during the two years following the deployment of this process, the rate of severe flow blockages caused by mineral accumulation in the facility's reinjection wells increased markedly.

Statement: The finding that the suspended silica micro-particles rapidly aggregate with ambient clay platelets upon entering the subterranean rock formation to form dense mineral plugs in rock fissures, if true, helps to resolve the apparent discrepancy described in the scenario.

Answer: Answer

Answer

True
The statement is true because it supplies an unexamined causal bridge that allows both premises to coexist: the flash-crystallized silica particles remain non-adherent within the metal piping, yet their physical presence triggers clogging when they interface with ambient clay in the rock formation fissures.

Step-by-Step Solution

1
Isolate the two conflicting facts presented in the stimulus
Fact 1: Flash-crystallization converts silica into suspended micro-particles that do not adhere to pipe walls. Fact 2: Mineral-induced flow blockages in the reinjection wells increased significantly after adopting the process.
A resolve-the-paradox evaluation requires identifying the exact tension between an expected benefit and an observed contrary outcome.
2
Assess the explanatory mechanism introduced in the statement
The auxiliary statement provides a mechanism where non-adhering particles chemically or physically interact with ambient clay platelets in the surrounding rock fissures to form mechanical clogs.
To resolve the paradox, the new information must allow both stated facts to remain true while explaining the causal link leading to the unexpected result.
3
Determine whether the statement successfully bridges the discrepancy
Because it explains how non-pipe-adherent particles cause subterranean well blockages without denying the pipeline test findings, the statement successfully resolves the paradox.
Mastery of paradox resolution requires confirming that the proposed fact harmonizes the apparent contradiction.
