Stimulus

Monroe, despite his generally poor appetite, thoroughly enjoyed the three meals he ate at the Tip‐Top Restaurant, but, unfortunately, after each meal he became ill. The first time he ate an extra‐large sausage pizza with a side order of hot peppers; the second time he took full advantage of the all‐you‐can‐eat fried peppers, Monroe concludes that it is solely due to Tip‐Top's hot peppers that he became ill.
