// Create and define Adult.

//1. Tell Student to inherit Adult.
//TODO: implement here

//2. Change the workDay method of Student so it returns "I have to do my homework."
//TODO: implement here

    //3. TODO: To check for inheritance replace ___ with true/false:

   assert(student instanceof Student === ___, "Should be instance Student?");
