Which of the following is NOT a common location to check for a missing child?

The reasoning behind the idea that shopping malls are not a common location to check for a missing child is based on certain assumptions about typical behavior patterns of children and their likelihood of wandering. While shopping malls can certainly attract children and potentially be a place where they might become separated from their guardians, the other options present locations where children are more likely to venture off on their own or may easily become lost.

Creeks, fairs, and arcades are more specific environments where children might be drawn to explore. For example, creeks are natural areas that could attract children who are curious about water and wildlife. Fairs often have a variety of attractions that captivate children's attention, encouraging them to wander away from their guardians. Arcades are entertainment venues specifically designed for children, which may lead them to stay and play without realizing how far from their guardians they have gone.

On the other hand, the structured environment of a shopping mall typically allows for better supervision and is often associated with adult supervision, making it a less probable location for a child to go missing compared to the other environments mentioned. Hence, while any location should be checked if a child is missing, shopping malls are perceived as less risky in terms of children straying too far from adult supervision.
