Difficulty: MediumRecognizing Implied Cause and Effect

During a routine production run at an industrial textile mill, operators adjusted the heated drying rollers to run ten percent faster to meet an urgent shipment deadline. Soon after the change, technicians noted that rolls of woven fabric entering the subsequent chemical dyeing bath absorbed the liquid dye unevenly, leaving faint streaks along the center of the bolts. Inspections confirmed that the chemical dye formulation remained identical to standard specifications and the bath temperature stayed constant throughout the shift.

Based on the passage, what most likely caused the uneven dye absorption in the fabric bolts?

  1. A
    The streak patterns along the fabric forced operators to accelerate the drying roller speed.
  2. The reduced contact time with the heated rollers left irregular residual moisture in the fabric before dyeing.Answer
  3. C
    The chemical dye formulation broke down due to steady temperatures in the liquid bath.
  4. D
    The mechanical rollers applied unequal physical pressure across the width of the fabric weave.

Answer

The reduced contact time with the heated rollers left irregular residual moisture in the fabric before dyeing.
The passage establishes that the only operational change prior to the dyeing defect was running the heated drying rollers faster. Because the chemical formulation and temperature were verified to be standard, the logical inference is that moving through the heated drying zone more quickly reduced drying time and left uneven moisture, preventing uniform dye absorption.

Step-by-Step Solution

1
Identify the primary operational change and its immediate chronological consequence
The drying rollers were set to run 10% faster, immediately preceding the appearance of uneven dye absorption.
Tracking what changed helps establish the origin of the downstream problem.
2
Evaluate and eliminate controlled variables mentioned in the text
The chemical dye formulation and the bath temperature were confirmed to be standard and constant.
Eliminating alternative factors isolates the roller adjustment as the sole variable.
3
Deduce the unstated physical link between faster heated rollers and liquid absorption
Faster passage through the heated rollers gave the fabric less drying time, causing uneven moisture retention that disrupted uniform dye uptake.
Connecting the known premises reveals the unstated causal mechanism.
