Question

Difficulty: EasyParagraph Summarization

Precision torque wrenches require routine calibration to ensure fasteners are tightened to exact manufacturer specifications. Over time, regular mechanical stress and temperature fluctuations cause internal springs to lose tension, leading to inaccurate torque readings. When bolts are improperly torqued, components may vibrate loose or suffer structural damage from overtightening. Regularly testing and readjusting these tools prevents equipment failure and maintains operational safety across mechanical maintenance facilities.

Which of the following statements best summarizes the passage?

  1. A
    Mechanical stress and temperature fluctuations cause internal springs to lose tension over time.
  2. B
    All mechanical tools must be replaced periodically to avoid facility hazards and system breakdowns.
  3. Routine calibration of torque wrenches is essential for preventing equipment damage and maintaining safety.Answer
  4. D
    Torque wrenches will cause catastrophic structural damage unless mechanics calibrate them before every single use.

Answer

Routine calibration of torque wrenches is essential for preventing equipment damage and maintaining safety.
The primary purpose of the passage is to explain why torque wrenches must be tested and adjusted routinely and how this practice protects machinery and personnel. The statement noting that routine calibration prevents equipment damage and maintains safety captures the full scope of the text concisely and accurately.

Step-by-Step Solution

1
Identify the central topic and scope of the paragraph.
The text discusses precision torque wrenches, why they lose calibration, and why regular testing is necessary.
Determining the subject helps distinguish the primary argument from minor supporting facts.
2
Evaluate the relationship between the supporting details and the concluding point.
Wear causes spring tension loss, which causes improper fastening, which is ultimately prevented by routine calibration.
A comprehensive summary must capture the main takeaway rather than an isolated cause or symptom.
3
Select the statement that captures both the requirement of calibration and its intended operational benefit.
The statement expressing that regular calibration prevents equipment damage and preserves safety accurately reflects the complete text.
The correct summary unifies the problem and the recommended practice without exceeding passage boundaries.
