staffed completely
Could I have this clear?
The question is
Members if the team often talk to ambulance staff during a rescue. True or false

And the text says

Many of our rescues involve radio communication with public emergency services, such us the police andr the ambulance.but, among these services , we are the only emergency service staffed completely by members who give up their free time in return for no financial reward.

I wonder if it is true or false.

Thanks

Answer

The answer to this question is true. They say that 'many of their rescues involve radio communication with public emergency services, such as the police and the ambulance [service]". They are communicating via radio - so they are talking to ambulance staff. There are a few mistakes in the text which I can correct if needed.
