During World War I, British merchant vessels were painted with complex patterns of geometric shapes, contrasting stripes, and optical illusions rather than solid ocean greys. These chaotic designs did not conceal the ships on the open water. Instead, the intersecting angles broke up each vessel's visual profile, making it difficult for submarine commanders to accurately estimate its heading, speed, and distance through a periscope. As a result, enemy torpedo gunners frequently miscalculated their firing angles and missed their targets.
Which of the following best expresses the unstated main idea of the passage?
- ASubmarine commanders relied heavily on periscope observations to calculate torpedo trajectories.
- BVisual deception is the single most effective defensive strategy across all forms of naval warfare.
- The geometric paint patterns protected ships by confusing enemy targeting rather than hiding the vessels.Cevap
- DGerman submarine crews failed primarily because their targeting equipment was improperly maintained.
Cevap
The geometric paint patterns protected ships by confusing enemy targeting rather than hiding the vessels.
The correct response combines the central premise (the patterns were not meant to hide the ship) with the primary consequence (disrupting torpedo calculations to protect the vessel).
