Question 1475Navigation General70% to pass

If several navigational lights are visible at the same time, each one may be positively identified by checking all of the following EXCEPT what against the Light List?

AI Explanation
The correct answer is D) Intensity. The reason is that the Light List, which is a reference for identifying navigational lights, does not provide information about the intensity of the lights. The Light List specifies the other characteristics of the lights, such as the period, rhythm, and color, which can be used to positively identify each light. However, the intensity of a light can vary depending on factors such as weather conditions, distance, and the observer's position, and is not a reliable identifier listed in the Light List.
