These usually produce a YES or NO answer. They can be useful in the closing minutes of the conversation to confirm all the small details and to make sure you have covered all the points that you need to know.
EXAMPLES:
1. HAVE YOU CONFIRMED THE RESERVATION WITH MY DEPARTMENT?
2. IS THERE ANY FURTHER INFORMATION THAT YOU NEED FROM ME AT THIS POINT?
3. DO YOU HAVE A COPY OF THE RESERVATION?
4. WOULD YOU LIKE ME TO SEND YOU A MAIL WITH THE DETAILS?
ACTIVITY: ASK THE CLASS TO COME UP WITH QUESTIONS THAT ARE RELATED TO THEIR WORK PLACE IN THE ABOVE FORMAT OF OPEN QUESTIONS.
