terminology – Aggregate textual data of a particular column

I have a dataset as follows

last_name firstname age Description Hobby
Smith John 20 High School Music
Johnson Robert 45 gardening software developer
Williams David 15 Junior Baseball School
Davis Michael 65 Traveler Skydiving
Miller Molly 25 Scientist Cycling 

Now I have a question from a mission that Aggregate textual data under "Description" and "Leisure"

I do not understand what is the meaning of aggregated text data?

If anyone understands the question, please share their point of view. I want to know theoretically how aggregated text data could depend on the Hobby description and column.

This is a python coding task. But currently, I do not care about coding. I want to know the theoretical meaning of this question and want to solve it manually.

Thanks in advance
