Final answer:
The loop sewn on top of a shoe tongue helps keep it in place by allowing laces to be threaded through, similar to fitting pegs into matching holes in a toy.
Step-by-step explanation:
A loop sewn on top can help keep the tongue in one of these from moving around. The correct answer is a) Shoe.
Shoes often come with a small loop sewn onto the tongue, which serves a functional purpose. The loop helps to keep the shoe tongue in place by allowing the laces to be threaded through it, much like how a square peg fits through the square hole and a round peg fits through the round hole of a children's toy. This design ensures that the tongue stays centered and does not slide to the side, providing a comfortable and secure fit for the wearer.
