Determine whether the set is well defined. The set of U.S. museums Choose the correct answer below. The set is well defined. The set is not well defined.

To determine whether the set of U.S. museums is well defined, we need to consider the criteria for a set to be well defined. A set is well defined if it has a clear and unambiguous definition that allows us to determine whether an object belongs to the set or not. In this case, the set of U.S. museums can be defined as follows: it includes all institutions in the United States that are dedicated to preserving and exhibiting objects of artistic, cultural, historical, or scientific significance. Since this definition is clear and specific, we can identify which institutions qualify as museums and which do not. Therefore, we can conclude that: **The set is well defined.**
