subquestions (Feature #253)

This can be implemented with the current version of AMC.

For my tests I do it in the following way:

Let's say I have two main questions in my test, A and B. A has two sub-questions and B has three sub-questions.

To give the descriptions for the main question on which the sub-questions are based I define a new command:

\def\insertMainQuestionA
{
    \\\textsc{Passage:}\\       % Header to be displayed before question A

    Consider the quadratic equation $ax^{2} - bx + c = 0,$ where $a, b, c \,\epsilon\, \mathbb{N}$ ,
    which has two distinct real roots belonging to the interval (1, 2).\par
    \vspace*{.5cm}
    \insertgroup{subQuestionA}      % This inserts sub-questions for main question A.
}

The sub-questions for this question are defined in a new element block:

\element{subQuestionA}
{
    \begin{question}{QA01}
        The least value of $a$ is
        \begin{choiceshoriz}
            \wrongchoice{4}
            \wrongchoice{6}
            \wrongchoice{7}
            \correctchoice{5}
        \end{choiceshoriz}
    \end{question}
}

\element{subQuestionA}
{
    \begin{question}{QA02}
        The least value of $b$ is
        \begin{choiceshoriz}
            \wrongchoice{10}
            \correctchoice{11}
            \wrongchoice{13}
            \wrongchoice{15}
        \end{choiceshoriz}
    \end{question}
}

Similary for the main question B:

\def\insertMainQuestionB
{
    \\\textsc{Passage:}\\       % Header to be displayed before question B

    Let us consider the equation $x^{2} - (m - 3) x + m = 0, (m \,\epsilon\,\mathbb{R})$. Answer the following questions.\par
    \vspace*{.5cm}
    \insertgroup{subQuestionB}      % This inserts sub-questions for main question B.
}

\element{subQuestionB}
{
    \begin{question}{QB01}
        The set of values of $m$ such that the given quadratic equation has one root smaller than 2 and the other root greater than 2.
        \begin{choiceshoriz}
            \wrongchoice{$(-\infty,10)$}
            \correctchoice{$(10,\infty)$}
            \wrongchoice{$(-\infty,10)\cup(10,\infty)$}
            \wrongchoice{$(-\infty,-10)$}
        \end{choiceshoriz}
    \end{question}
}

\element{subQuestionB}
{
    \begin{question}{QB02}
        The set of values of $m$ such that the given quadratic equation has both roots greater then 2
        \begin{choiceshoriz}
            \wrongchoice{$[10,\infty)$}
            \wrongchoice{$(-9,10)$}
            \wrongchoice{$[9,10]$}
            \correctchoice{$[9,10)$}
        \end{choiceshoriz}
    \end{question}
}

\element{subQuestionB}
{
    \begin{question}{QB03}
        The set of values of $m$ such that the given quadratic equation has exactly one root between (1, 2).
        \begin{choiceshoriz}
            \wrongchoice{$(-\infty,10)$}
            \wrongchoice{$(9,10)$}
            \correctchoice{$(10,\infty)$}
            \wrongchoice{$(9,10]$}
        \end{choiceshoriz}
    \end{question}
}

The main questions now have to defined in a new element block so that they can be shuffled and inserted in the test.

\element{mainQuestion}
{
    \noindent
    \insertMainQuestionA
}

\element{mainQuestion}
{
    \noindent
    \insertMainQuestionB
}

To shuffle the sub-questions:

\shufflegroup{subQuestionA}
\shufflegroup{subQuestionB}

To shuffle the main questions:

\shufflegroup{mainQuestion}

Now to add the main questions to the test:

\insertgroup{mainQuestion}

I hope this will be helpful for you.

I am attaching a .tex file which implements this. You can modify it for your own use.
