 a. Where is closure used in this code? How can you tell?
+  return function(){ on line 53 because it will create a function within the function.
 b. Compare and contrast calling `dansRoll` the first and second time. What is always the same? What could change?
+The phrase "Dan rolled a" stays the same. The number he rolls generally changes.
+
 c. What is the lexical scope of `newRoll`?
