Which of the following gives the clearest relative location of Milwaukee?

The choice that provides the clearest relative location of Milwaukee is the description of its distance from Chicago, stating it is 100 miles north of that city. Relative location refers to a place's position in relation to other locations, which helps to provide context for where it is situated geographically and how it connects with surrounding areas.

Milwaukee is located in the state of Wisconsin and is on the shores of Lake Michigan, but these descriptions are more about its absolute location rather than its situational context in relation to another major city. Saying it is "100 miles north of Chicago" effectively conveys its position in terms of familiar landmarks and distances that can be easily understood by someone who may not know the exact coordinates or state boundaries, thus making it the clearest option for relative location.

In contrast, stating “in Wisconsin” or “on Lake Michigan” gives a more general geographical context rather than a specific relative position. Describing its coordinates (44° N, 88° W) provides absolute or specific information but lacks the contextual framework that helps someone visualize where Milwaukee is in relation to a well-known reference point like Chicago.
