 questions provide a way for the students to check themselves as they go along.  The questions also provide feedback so that you can
 understand why an answer may or may not be correct.

+   :answer_a: Python
+   :answer_b: Java
+   :answer_c: C
+   :answer_d: ML
+   :feedback_a: Yes, Python is a great language to learn, whether you are a beginner or an experienced programmer.
+   :feedback_b: Java is a good object oriented language but it has some details that make it hard for the beginner.
+   :feedback_c: C is an imperative programming language that has been around for a long time, but it is not the one that we use.
+   :feedback_d: No, ML is a functional programming language.  You can use Python to write functional programs as well.
+
+   What programming language does this site help you to learn?
 
 This next type of question allows more than one correct answer to be required.  The feedback will tell you whether you have the
 correct number as well as the feedback for each.

+    :feedback_b: Yes, yellow is correct.
+    :feedback_c: Remember the acronym...ROY G BIV.  B stands for blue.

 Another type of question allows you as the instructor to ask for a value.  You can test for the value using Pythons regular expressions.  For example:
 
 
-.. fillintheblank:: fill1412
+.. fillintheblank:: fill1512
 
     .. blank:: blank21
-        :correct: \\bblue\\b
-        :feedback1: ("\\bred\\b", "You are an awful person.")
-        :feedback2: (".*", "(Hint: Sail Norse)")
+        :correct: \\b31\\b
+        :feedback1: ("\\b25\\b", "That's base 10!")
+        :feedback2: (".*", "25 in octal please!")
 
-        What is the best color?
+        What is the value of 25 expressed as an octal number (base 8)?
 
 And finally here is a way of giving your students some simple programming problems where the code is already there for them but not indented or in the correct order.  Use drag-and-drop to get everthing right.

+        :feedback_c: Results will differ depending on the exact location of the element, but Binary Search will still find the element faster while Sequential will have to check more elements.
+        :feedback_d: If the search value is not in the array, a sequential search will have to check every item in the array before failing, a binary search will be faster.
+        :feedback_e: When the search value is the first element, Sequential will always be faster, as it will only need to check one element.
 
+        Under which of these conditions will a sequential search be faster than a binary search?
