In the analogy Glove : Hand, the relationship is that of clothing to the body part it covers. A glove is worn on a hand. Applying this same logic to the analogy Sock : ?, we need to identify the body part a sock covers.
- Shoe: A shoe is an outer covering for the foot, not the item worn directly on the foot itself in this analogy.
- Foot: A sock is worn directly on the foot, mirroring the glove-to-hand relationship.
- Head: A sock is not worn on the head.
- Leg: While the leg is part of the lower limb, a sock specifically covers the foot.
Thus, the correct completion of the analogy Sock : Foot is established because a sock is worn on a foot, directly analogous to a glove being worn on a hand.
