Thanks, we will make the necessary change. In the meantime, please use exercise3-output.ttl as the input to the Exercise 5.

Exercise 5 needs exercise4-output.ttl as one input to get capital information. It indicates that this file should have countries and their capitals generated in Exercise 4. In fact, in exercise 4, we only added abbrev3 property to exercise3-output.ttl. Thanks.
