Zorluk: OrtaExplicit Main Idea

Passage:
Naval degaussing systems reduce a warship's magnetic signature to prevent the detonation of underwater magnetic influence mines. By routing controlled direct electrical current through a network of heavy copper coils installed throughout the ship's hull, these systems generate an opposing magnetic field that neutralizes the vessel's permanent and induced magnetization. Modern installations continuously adjust coil currents based on real-time readings from onboard triaxial magnetometer sensors, compensating for changes in geographic latitude and ship orientation. While this magnetic masking does not protect against acoustic or visual tracking methods, it significantly diminishes the vulnerability of surface combatants navigating shallow littoral minefields.

Statement: The primary purpose of naval degaussing systems is to neutralize a ship's magnetic field to protect it against underwater magnetic mines.

Cevap: Cevap

Cevap

True
The statement accurately reflects the explicitly stated central idea found in the first sentence of the passage, which defines the core purpose of naval degaussing systems as reducing magnetic signatures against mine threats.

Adım Adım Çözüm

1
Locate the explicit topic sentence in the passage
The opening sentence directly states: 'Naval degaussing systems reduce a warship's magnetic signature to prevent the detonation of underwater magnetic influence mines.'
Explicit main ideas are directly stated by the author, frequently in the initial sentence as the overarching claim.
2
Compare the provided statement with the passage's explicit claim
The statement accurately captures the central concept without distorting scope or introducing unsupported assertions.
Verification confirms that the statement mirrors the passage's primary topic rather than a secondary technical detail.
