Question 13 Deck General

The correct answer is B) a little above the horizon. When standing lookout at night, the dim light on the horizon will be seen quickest by looking a little above the horizon. This is because the human eye is more sensitive to light just above the horizon, where the contrast between the dim light and the darker sky is greatest. Looking directly at the light (option D) or below the horizon (option C) reduces the contrast and makes the light harder to detect. Quickly scanning above and below the horizon (option A) is less effective than simply focusing a little above the horizon.
