<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am working on a problem for an upcoming exam. In the past I have just done it via paper exam, which was fine until now. (I did plan to do it in LON-CAPA someday, but thanks to Corona, someday is now here.)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem starts with an optionresponse. After the student answers it, I want to show a radiobuttonresponse problem, then show a figure and a matrix equation containing 15 parts. In the past I have used the “display-one-part-at-a-time”
feature, but the catch is that the matrix equation has 15 parts in it, and I need to show the figure and all 15 parts of the matrix equation at the same time, right after the radio button problem.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I suspect I can do it with a <block></block> tag, but am having trouble finding examples of conditional expressions and variables that I can use inside the <block> code. Does anyone know of a good resource for that info, or know the parameters
and syntax I need to use? I have explored the authoring guide and LON-CAPA online help, done web searches, and looked through YouTube, all to no avail…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best regards,<o:p></o:p></p>
