<p>The mathematical summary of many of the theory of relativity developed by Einstein is that the amount of energy contained in a mass m is the mass time the speed of light squared.</p>
<p>As you can see with the formula entry, the answer is \(\frac{R_1*R_2}{R_3}\)</p>
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.</p>
<p> 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.

<p>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.</p>
<p>
The answer options and the identification of the correct answer is defined in the <b>optioninput</b> tag.
</p>
<p>Translation between Option Response and __________ is extremely straightforward:
<p>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.</p>
A string response problem accepts a line of text input from the
student, and evaluates the input for correctness based on an expected
answer within each input box.
The answer is correct if it is the expected answer.
A string response problem accepts a line of text input from the
student, and evaluates the input for correctness based on an expected
answer within each input box.
The answer is correct if it matches every character of the expected answer. This can be a problem with international spelling, dates, or anything where the format of the answer is not clear.
