text: 1. Make sure you are still in the SWRLTab. Click on the HotDiscountRule and select Clone 
  
  2. This should bring up the same window you used to create your first rule with the code for that rule in 
  the window. Change the name of this rule from S1 to LessSpicyDiscountRule. 
  
  3. Next edit the test for the Customer’s spiciness preference. Rather than just testing if it is Hot we want 
  to test this time if it isMilderThan Hot. This is an example of using the order relation we defined in 
  chapter 6. Change hasSpicinessPreference(?c, Hot) to hasSpicinessPreference(?c, ?spr). Rather than just 
  test if it is equal to Hot we need to bind the preference value to the parameter ?spr. Then after this add 
  the usual and character and the new test, so you should add: ^ isMilderThan(?spr, Hot) 
  
  4. Finally, we want to change the discount for these Customers to be 10% rather than 20%. So change the 
  consequent to be: hasDiscount(?c, 0.1). 
  
  5. Thus the whole rule should look like: Customer(?c) ^ numberOfPizzasPurchased(?c, ?np) ^ 
  hasSpicinessPreference(?c, ?spr) ^ isMilderThan(?spr, Hot) ^ swrlb:greaterThan(?np, 1) -> 
  hasDiscount(?c, 0.1).
