What is a first-level and second-level sort, and what is a situation where you would use both levels?
What will be an ideal response?
You can sort by more than one column of data. The columns will be sorted in order by the first-level sort criteria first, and then by the second-level sort criteria.
Example (Answers will vary): You might want to sort a list of names in alphabetical order by last name and then within last names by first name. In this case, you need to create a sort with different levels of criteria. The last name is the first-level sort and the first name is the second-level sort.
