Zorluk: ZorResolve the Paradox

A municipal water authority in a desert metropolis installed high-precision automated acoustic leak-detection sensors throughout its subterranean pipe network. Within one year of full deployment, municipal repair crews detected and repaired three times as many underground pipe leaks as they had in any previous year. Paradoxically, during that same one-year period, the total volume of treated water lost to subterranean leaks across the municipal system increased by more than 15 percent, even though overall water consumption and the total number of new pipe ruptures remained unchanged from previous annual averages.

Which of the following, if true, most helps to resolve the apparent paradox described above?

  1. A
    Prior to the installation of the acoustic sensors, municipal utility workers relied primarily on visible surface pooling and citizen complaints to identify subterranean pipe breaches.
  2. B
    The acoustic monitoring sensors were engineered to identify the vibrational frequencies produced by catastrophic, high-volume main breaks far more rapidly than those produced by small fissures.
  3. Because the sensors flagged thousands of previously undetected micro-leaks, repair crews spent the vast majority of their time excavating minor fissures, substantially increasing the response time required to reach and fix rare, high-volume pipeline fractures.Cevap
  4. D
    All aging municipal water distribution networks inevitably experience increasing volumetric water loss each year, regardless of the speed or frequency of maintenance interventions.
  5. E
    Municipal water treatment facilities recently upgraded their filtration equipment to comply with new regional environmental quality standards.

Cevap

The statement explaining that fixing thousands of newly detected micro-leaks caused repair crews to take substantially longer to respond to rare, high-volume pipeline fractures resolves the paradox.
The correct response introduces an operational bottleneck: the vast influx of detected micro-fissures absorbed repair crew resources, which substantially lengthened the duration that rare, large-volume main bursts were left flowing before crews arrived. Because a single large rupture can discharge far more water over several hours than hundreds of pinhole leaks lose over weeks, this resource shift perfectly reconciles a 300% increase in completed repairs with a 15% increase in total volume lost.

Adım Adım Çözüm

1
Identify the two seemingly conflicting factual premises in the stimulus.
Premise 1: Repair crews fixed three times as many underground leaks as in any previous year, with new ruptures and total consumption remaining constant. Premise 2: Total volume of water lost through leaks increased by over 15 percent.
Resolving a paradox requires isolating the tension between the action taken (tripling repairs) and the counterintuitive outcome (higher total water loss).
2
Formulate a causal bridge that allows both facts to be simultaneously true without denying either premise.
Look for a factor showing that the composition or duration of leaks changed—specifically, that although the number of repaired leaks increased, the volume lost per unit time or duration of major leaks increased due to diverted repair capacity.
Total water loss depends on both the rate of discharge and the duration of each leak, not merely the raw count of repaired leaks.
3
Evaluate the choices to find the one that provides this causal bridge.
The explanation detailing that repair crews became tied up with micro-leaks, delaying response to major high-volume bursts, accounts for both the higher repair count (thousands of micro-leaks fixed) and the higher aggregate volume lost (major bursts ran longer).
This bridges the gap by showing that count of repairs went up while the severity/duration of unaddressed high-loss events worsened.
