Drop the Latitude and Longitude columns from volunteer, storing as volunteer_cols.
Subset volunteer_cols by dropping rows containing missing values in the category_desc, and store in a new variable called volunteer_subset.
Take a look at the .shape attribute of volunteer_subset, to verify it worked correctly.
