If you're willing to use a theorem-like environment, and amsthm, this question provides a method: https://tex.stackexchange.com/q/201956 — barbara beeton, Dec 26 '22 at 21:34

You may find your solution with AMS-theorem extension (short and long docs)

\documentclass{article}
\usepackage{amsthm}
\begin{document}
    \theoremstyle{definition} % default is plain
    \renewcommand{\qedsymbol}{$\blacksquare$} % standard is white
    \newtheorem{myquestion}{Question} % prefix numbering
    \section{Test}
    \begin{myquestion}
        Countries acros the world have been growing persistently since at least year 1200.
    \end{myquestion}
    \begin{myquestion}
        We use a logarithmic scale to plot the graph of a variable.
    \end{myquestion}
\end{document}

From Denoting the end of example/remark

\documentclass{article}
\usepackage{amsmath,amsthm}
\providecommand*{\blacksquare}{\rule{1ex}{1ex}}
\theoremstyle{definition}
\newtheorem{question}{Question}[section]
\AtBeginEnvironment{question}{%
  \pushQED{\qed}\renewcommand{\qedsymbol}{$\blacksquare$}%
}
\AtEndEnvironment{question}{\popQED\endquestion}
\begin{document}
\section{First Section}
\begin{question}
  Countries across the world have been growing persistently since at
  least year 1200.
\end{question}
\begin{question}
  We use the logarithmic scale to plot the graph of a variable so that
  the same growth rates at different levels of that variable appear as
  the same slopes of the graph.
\end{question}
\end{document}

Remove [section] if you don't want the counter to be section-dependent.

This really makes the question a duplicate. – barbara beeton Dec 27 '22 at 17:35 — barbara beeton, Dec 27 '22 at 17:35
