如何在多列考试类中创建顶部带有数字的坐标网格

Question

我正在尝试弄清楚如何更改以下内容。当我编写以下代码时，我会在图像底部获得第二个问题标签。如果我在第二个问题之后的第一个问题之前添加 // 以使网格位于另一行，我会收到错误，即这里没有行可以结束，这是可以理解的。这是 MWE。

    \documentclass{exam}
    \usepackage{multicol,tikz}

    \begin{document}
    Instructions here.
    \begin{questions}
    \begin{multicols}{2}
    \question
    First Question

    \columnbreak

    \question
    \begin{tikzpicture} [xscale=0.35, yscale=0.35] %Change size of grid
    \draw[help lines] (-10,-10) grid (10,10);
    \draw[<->, ultra thick] (-10,0) -- (10,0); %x-axis
    \draw[<->, ultra thick] (0,-10) -- (0,10); %y-axis
    \node[right] at (10,0) {$x$}; %label x-axis
    \node[above] at (0,10) {$y$}; %label y-axis
    \end{tikzpicture}
    \end{multicols}
    \end{questions}
    
    \end{document}

我可以通过添加如下文本来解决这个问题，但这不是一个理想的解决方案。

    \documentclass{exam}
    \usepackage{multicol,tikz}

    \begin{document}
    Instructions here.
    \begin{questions}
    \begin{multicols}{2}
    \question
    First Question

    \columnbreak

    \question
    Here's some text\\
    \begin{tikzpicture} [xscale=0.35, yscale=0.35] %Change size of grid
    \draw[help lines] (-10,-10) grid (10,10);
    \draw[<->, ultra thick] (-10,0) -- (10,0); %x-axis
    \draw[<->, ultra thick] (0,-10) -- (0,10); %y-axis
    \node[right] at (10,0) {$x$}; %label x-axis
    \node[above] at (0,10) {$y$}; %label y-axis
    \end{tikzpicture}
    \end{multicols}
    \end{questions}
    
    \end{document}

如果可能的话，我确信我需要更改某些属性。我只是在 multicol 或 TikZ 的文档中找不到它。如能提供任何帮助，我将不胜感激！

baseline您可以更改tikzpicture

\documentclass{exam}
    \usepackage{multicol,tikz}

    \begin{document}

    \begin{questions}
    \begin{multicols}{2}
    \question
    First Question

    \columnbreak

    \question
    \begin{tikzpicture} [xscale=0.35, yscale=0.35, baseline=(current bounding box.north)] %Change size of grid
    \draw[help lines] (-10,-10) grid (10,10);
    \draw[<->, ultra thick] (-10,0) -- (10,0); %x-axis
    \draw[<->, ultra thick] (0,-10) -- (0,10); %y-axis
    \node[right] at (10,0) {$x$}; %label x-axis
    \node[above] at (0,10) {$y$}; %label y-axis
    \end{tikzpicture}
    \end{multicols}
