I want to know the answer to the following question:
What is one way that videocalling can be used?
All the background I'm provided with is that "New services utilizing videocalling and videoconferencing, such as teachers and psychologists conducting online sessions, personal videocalls to inmates incarcerated in penitentiaries, and videoconferencing to resolve airline engineering issues at maintenance facilities, are being created or evolving on an ongoing basis.". Is that enough to answer the question?
Answer: yes
