Hi Eric,

This line calls the method 'checkCave()'. This method takes the argument caveNumber (checkCave(caveNumber) , which is a string returned from user input generated in the method chooseCave().

In checkCave method, the value (caveNumber) is then used in a if/else statement to compare with a random integer (parsed to a string str(frindlyCave))  to determine whether you will be eaten or given treasure ;)

Hope that was of some help.
