Zorluk: Çok zorParaphrased Fact Recognition

Read the following passage:

In high-voltage overhead transmission lines, persistent low-amplitude aeolian vibrations, caused by steady crosswinds, can induce severe fatigue failure at conductor attachment points. To counteract this relentless mechanical stress, engineers deploy Stockbridge dampers. These dumbbell-shaped devices consist of two suspended masses attached to a short length of flexible cable. Rather than preventing the wind from interacting with the power lines, the dampers dissipate the accumulated kinetic energy. As the main transmission cable oscillates, the damper's flexible cable flexes, converting the destructive vibrational energy into harmless heat through internal inter-strand friction, thereby extending the operational lifespan of the grid infrastructure.

Based on the passage, by what specific mechanism do Stockbridge dampers protect transmission infrastructure?

  1. By altering detrimental mechanical movement into thermal output via the rubbing of their own suspension elements.Cevap
  2. B
    By utilizing two suspended masses to prevent the wind from interacting with the power lines.
  3. C
    By converting accumulated thermal heat into harmless vibrational energy through the flexing of the transmission cable.
  4. D
    By adding rigid structural weight to the conductors to minimize their movement during severe storms.

Cevap

The correct answer is the option stating that dampers protect the infrastructure by altering detrimental mechanical movement into thermal output via the rubbing of their own suspension elements.
The text explicitly states the mechanism of protection: the dampers operate by 'converting the destructive vibrational energy into harmless heat through internal inter-strand friction'. The correct option accurately translates this sequence using synonyms. 'Detrimental mechanical movement' replaces 'destructive vibrational energy', 'thermal output' replaces 'heat', and 'rubbing of their own suspension elements' paraphrases 'internal inter-strand friction'.

Adım Adım Çözüm

1
Analyze the question stem to determine the specific fact required.
The question asks for the 'specific mechanism' by which the dampers protect the infrastructure.
Focusing the search prevents being distracted by general descriptive details about the dampers.
2
Locate the sentence in the passage that explicitly describes the mechanism of action.
The mechanism is found in the final sentence: 'converting the destructive vibrational energy into harmless heat through internal inter-strand friction'.
This is the precise factual detail that must be matched to a paraphrased option.
3
Evaluate the options to find the one that accurately translates the located fact using synonyms.
The correct option maps 'destructive vibrational energy' to 'detrimental mechanical movement', 'harmless heat' to 'thermal output', and 'inter-strand friction' to 'rubbing of their own suspension elements'.
A valid paraphrase retains the exact meaning and logical relationship of the original text while entirely replacing the vocabulary.
4
Verify that the selected option avoids verbatim traps and logical inversions.
The correct option correctly preserves the cause-and-effect flow (movement to heat) without relying on exact wording pulled out of context.
Highly difficult questions often use exact words from the text to create plausible but factually incorrect distractors.
