Hi:
Answer from instructors:
Notice that there are 2 columns on the Filter tab: Facility Continent and Facility Country. Even though you don't see the check under Continent, the fact that these 2 columns are listed on the Filter pane show you that there are 2 filters.
Then, under the Visualization area, there is an additional filter for Product Brand.
However, the question was about the number of filters for the data source and the correct answer is two, as shown below:
Hope this helps explain the reason for the answer.
