Question 410Navigation General

The correct answer is A) considerably reduced. The glare from the town in the background can reduce the range at which a lighthouse can be sighted. The glare makes it more difficult to distinguish the lighthouse light from the background illumination, effectively reducing the visible range of the lighthouse. This is because the glare from the town can diminish the contrast between the lighthouse light and the surrounding environment, making it harder to detect the lighthouse signal. The other answer choices are incorrect because: B) the color of the lighthouse light does not affect the impact of the glare, C) the glare will in fact reduce the visible range, and D) the extra lighting from the town does not increase the range, but rather reduces the contrast and visibility of the lighthouse light.
