Could you cook a meal for twenty people?

Could you run for five miles without stopping?

Could you live a big city one day?

Do you think you could write a novel?

Do you think you could be the chief executive of a large company?

Could you hold your breath for a minute?

Could you give a speech in front of a hundred people?

Could you tell a lie if you really needed to?

Do you think you could learn another new language?

Could you do a parachute jump?

Do you think you could tell the whole truth all the time?

Could you find your way home from here with your eyes closed?
