Read the passage below:
Before the advent of radar, military engineers constructed massive concrete acoustic mirrors along coastlines to detect incoming enemy aircraft by capturing engine rumble. While these monolithic structures successfully concentrated distant ambient noises, their practical utility was severely undermined by unpredictable coastal winds and background surf. Consequently, operators frequently misidentified harmless seaside commotion as approaching bombers. Though an ingenious application of basic wave mechanics, the technology ultimately proved far too finicky and erratic for dependable defense operations.
Which of the following best describes the author's tone toward early acoustic detection technology?
- AUnreserved praise for its technological breakthrough
- BHostile outrage over the waste of military funds
- Respectful recognition of its clever concept alongside clear criticism of its operational unreliabilityCevap
- DObjective indifference toward coastal defense mechanisms
Cevap
Respectful recognition of its clever concept alongside clear criticism of its operational unreliability
The correct response captures both dimensions of the author's attitude: genuine appreciation for the scientific principle ('ingenious application') combined with a frank, critical assessment of its operational flaws ('severely undermined', 'finicky and erratic').
