"A multiple choice problem presents radio buttons for student input. Students can only select a single
option presented. Multiple Choice questions have been the subject of many areas of research due to the early
invention and adoption of bubble sheets.
One of the main elements that goes into a good multiple choice question is the existence of good distractors.
That is, each of the alternate responses presented to the student should be the result of a plausible mistake
that a student might make.

"A numerical response problem accepts a line of text input from the

numerical value.
The answer is correct if it is within a specified numerical tolerance
of the expected answer.
Enter the numerical value of Pi:

Enter the approximate value of 502*9:
= 4518 +- 15%
Enter the number of fingers on a human hand:

<solution>
<div class='detailed-solution'>
Explanation
Pi, or the the ratio between a circle's circumference to its diameter, is an irrational number
known to extreme precision. It is value is approximately equal to 3.14.
Although you can get an exact value by typing 502*9 into a calculator, the result will be close to
500*10, or 5,000. The grader accepts any response within 15% of the true value, 4518, so that you
can use any estimation technique that you like.
If you look at your hand, you can count that you have five fingers.

"OptionResponse gives a limited set of options for students to respond with, and presents those options
in a format that encourages them to search for a specific answer rather than being immediately presented
with options from which to recognize the correct answer.
The answer options and the identification of the correct answer is defined in the <b>optioninput</b> tag.

[[(Multiple Choice), String Response, Numerical Response, External Response, Image Response]]
<solution>
<div class='detailed-solution'>
Explanation
Multiple Choice also allows students to select from a variety of pre-written responses, although the
format makes it easier for students to read very long response options. Optionresponse also differs
slightly because students are more likely to think of an answer and then search for it rather than
relying purely on recognition to answer the question.
