        Suppose ${\bf x}$ is the following array:
    </p>
    <pl-variable-output digits="0">
        <pl-variable params_name="x">x</pl-variable>

        <p>
            Enter the components of ${\bf x}$.
            The attribute <code>allow-partial-credit="true"</code> is used, so each correct entry receives a partial score.
            By default, when <code>allow-partial-credit="true"</code>, the attribute <code>allow-feedback</code> is also set to <code>true</code>,
            and hence the submission panel indicates which entries are incorrect.

            Enter the components of ${\bf A}$. Here we use <code>allow-partial-credit="true"</code>
            and <code>allow-feedback="false"</code>. Hence, each correct entry receives a partial score, but the submission panel
            does not indicate which entries are incorrect.

            This is a very long vector, it should be able to scroll.  Enter the vector whose values are increasing integers in the range $1$ to $20$ (inclusive).

            With the attribute <code>allow-blank="true"</code> (which is false by default), entries can be left blank to represent a zero, so you may leave the elements with a zero blank.
