1. Problem Description
The problem asks whether "A collection of 6th grade textbooks" is well-defined. In the context of sets, a set is well-defined if it is possible to determine whether any particular object belongs to the set.
2. Solution Steps
A collection is well-defined if we can clearly identify the elements that belong to it. In this case, the collection is "6th grade textbooks". We know what textbooks are, and we know what "6th grade" means. Therefore, if we have a book, we can determine whether it is a 6th-grade textbook or not. This means the collection is well-defined.
3. Final Answer
Yes, it is a well-defined collection.
