I want to know the answer to the following question:
Beyonce's mother worked in what industry?
All the background I'm provided with is that "Beyoncé Giselle Knowles was born in Houston, Texas, to Celestine Ann "Tina" Knowles (née Beyincé), a hairdresser and salon owner, and Mathew Knowles, a Xerox sales manager.". Is that enough to answer the question?
