Zorluk: Çok zorLogical Arguments and Causal Relationships

An industrial research group analyzed 80 semiconductor manufacturing facilities over a three-year period to evaluate the impact of an Automated Predictive Maintenance (APM) system on equipment failure rates. The study recorded that facilities operating APM software experienced 40% less unplanned downtime than facilities operating without APM.

Critics argue that this observed correlation does not prove causation, hypothesizing instead that facilities electing to adopt APM already possessed superior quality-control protocols and newer machinery, which independently caused the lower downtime.

Based on the information above, which of the following joint selections correctly identifies both a finding that most strongly supports the claim that APM adoption directly caused the reduction in downtime (Column 1) AND a finding that most strongly supports the critics' counter-explanation (Column 2)?

  1. Column 1: Facilities adopting APM mid-study experienced an immediate 40% drop in downtime while keeping machinery age and maintenance protocols constant; Column 2: Facilities with older machinery that adopted APM experienced no reduction in downtime relative to non-adopting facilities of identical machinery age.Cevap
  2. B
    Column 1: Facilities with older machinery that adopted APM experienced no reduction in downtime relative to non-adopting facilities of identical machinery age; Column 2: Facilities adopting APM mid-study experienced an immediate 40% drop in downtime while keeping machinery age and maintenance protocols constant.
  3. C
    Column 1: High baseline downtime directly compelled facility managers to purchase APM software; Column 2: Facilities adopting APM mid-study experienced an immediate 40% drop in downtime while keeping machinery age constant.
  4. D
    Column 1: Facilities with newer machinery recorded significantly lower downtime before APM was commercially released; Column 2: Facilities across all machinery age brackets experienced an identical 40% drop in downtime following APM installation.
  5. E
    Column 1: Facilities adopting APM mid-study experienced an immediate 40% drop in downtime while keeping machinery age constant; Column 2: Sharp increases in equipment downtime caused plant managers to deactivate APM modules.

Cevap

Column 1: Facilities adopting APM mid-study experienced an immediate 40% drop in downtime while keeping machinery age and maintenance protocols constant; Column 2: Facilities with older machinery that adopted APM experienced no reduction in downtime relative to non-adopting facilities of identical machinery age.
The correct selection properly assigns the logical roles. To strengthen the claim that APM adoption directly causes lower downtime (Column 1), one must rule out alternative explanations by demonstrating an immediate drop in downtime following APM installation while holding pre-existing variables constant. To support the critics' counter-explanation (Column 2), one must show that APM adoption provides no benefit in the absence of superior machinery/protocols, confirming that the pre-existing factors were driving the observed performance.

Adım Adım Çözüm

1
Analyze the core argument and the critics' counter-hypothesis.
Primary claim: APM adoption directly reduces unplanned downtime. Critics' counter-explanation: Pre-existing factors (newer machinery, stricter protocols) caused lower downtime, making the APM correlation spurious.
Establishing the exact logical roles required for Column 1 (Strengthens APM causation) and Column 2 (Supports critics' counter-explanation).
2
Identify the finding that strengthens the APM causal claim for Column 1.
A finding showing that when APM is introduced while controlling for confounding variables (machinery age and protocols remain constant), downtime drops immediately.
Controlling for confounding variables isolates APM as the sole cause of the downtime reduction.
3
Identify the finding that supports the critics' counter-explanation for Column 2.
A finding showing that when APM is introduced into facilities without newer machinery or strict protocols, it fails to produce a downtime reduction.
This demonstrates that APM alone is ineffective without the underlying pre-existing facility characteristics, validating the critics' argument.
4
Match findings to Column 1 and Column 2 in correct order.
Column 1 must contain the controlled mid-study drop evidence, and Column 2 must contain the ineffective APM on older equipment evidence.
Ensures column assignments are not reversed.
