What exactly was the question? The question as you wrote it in your original post does not imply the existence of an azeotrope, and you don't need to invoke one to answer the question.
If the book insists that there is a low-boiling azeotrope of acetone and water, what would that imply about the volatility of a mixture of acetone and water? How would the boiling point of droplets of the azeotrope on the glassware compare to the boiling point of droplets of water on the glassware?
