Latex 考试类别左边距中的问题标签

Question

当我添加问题标签时，它超出了左边距。

这里有一个最小代码：

\documentclass[11pt,a4paper]{exam}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[left=2.5cm,right=2.5cm,top=2.5cm,bottom=2.5cm,showframe]{geometry}
\usepackage{setspace}
\usepackage{fancybox}

\renewcommand{\thequestion}{\bf\arabic{question}}
\renewcommand{\questionlabel}{\bf\llap{Q}\thequestion.}


\begin{document}

\begin{questions}
    \question This is the first question
    \question This is the second question
    \question Another question
\end{questions}

\end{document}

这里给出的结果

我该如何解决这个问题？
