How should the pillow be positioned?

• A. Open edge must face toward the head of the bed.
• B. Open edge must face the foot of the bed.
• C. Open edge should face away from the latrine.
• D. Open edge facing the latrine.

Answer: (D)

The idea here is hygiene and contamination control in a sleeping area: the pillow should be oriented so that any dirtiest edge faces the latrine, keeping the surface that contacts the sleeper cleaner. The open edge of a pillowcase is where dirt, skin oils, and moisture are most likely to accumulate as you insert or remove the pillow. By directing that open edge toward the latrine, any potential contamination from that nearby dirty area is kept away from the part of the pillow that touches the sleeper’s face, while the cleaner, closed edge faces toward the sleeper. This arrangement helps reduce the chance of contaminants reaching the face during rest and makes cleaning and maintenance more straightforward. If the opening faced the sleeper’s head, or pointed away from the latrine, contaminants could more easily migrate toward the surface that touches the face, increasing exposure.
