Difficulty: MediumWord Precision and Clarity

Civil engineers monitor the structural integrity of historical stone bridges using ground-penetrating radar, a non-destructive testing method that transmits high-frequency radio waves into masonry. By analyzing the reflected signals, technicians can ascertain internal voids and micro-fractures before catastrophic failures occur. This diagnostic technique ensures that restoration efforts are targeted accurately while preserving ancient architecture.

Which choice best maintains the precision and formal tone of the passage?

  1. NO CHANGEAnswer
  2. B
    catch on to
  3. C
    contemplate
  4. D
    site

Answer

The correct choice is 'NO CHANGE' because 'ascertain' precisely describes determining or finding out structural flaws with certainty in a formal, technical context.
The original word 'ascertain' accurately conveys the concept of determining or discovering facts with certainty through systematic technical analysis. It fits both the precise meaning needed (identifying hidden flaws) and the formal academic register of the passage.

Step-by-Step Solution

1
Analyze the context and intended meaning of the underlined word.
The sentence describes technicians using radar signal analysis to determine or detect hidden internal voids and micro-fractures in stone bridges.
Word precision questions require selecting a word that accurately captures the specific action taking place.
2
Evaluate the register and tone of the passage.
The text maintains a formal, technical, and objective academic tone.
The chosen word must align with the established level of formality in the surrounding text.
3
Compare the underlined word 'ascertain' with the alternative options.
'Ascertain' means to find out or learn with certainty, fitting both the exact meaning and formal tone. 'Catch on to' is too informal, 'contemplate' means to ponder rather than detect, and 'site' is contextually and grammatically incorrect.
Only 'ascertain' satisfies both precision of meaning and consistency of register.
