幻灯片内的字幕 (Beamer)

Question

我想将 Beamer 演示文稿的幻灯片分为两部分：RQ 和贡献。与我附上的 MWE 相比，有没有更聪明的方法？如能得到任何帮助，我将不胜感激。

\documentclass{beamer}
\usepackage[backend=bibtex,style=authoryear]{biblatex}
\usepackage{mathtools}
\usepackage{bm}
\usepackage{amsmath}                                      % Math equations, etc.
\mode<presentation> {
\usepackage{graphicx}
\usepackage{caption}
\usepackage{tabularx,booktabs,dcolumn}
\usetheme{Boadilla}

\usepackage{graphicx}% http://ctan.org/pkg/graphicx
\usepackage{booktabs}% http://ctan.org/pkg/booktabs


\usepackage[style=authoryear]{biblatex}
\renewcommand*{\nameyeardelim}{\addcomma\addspace}

\setbeamertemplate{navigation symbols}{} % To remove the navigation symbols from the bottom of all slides uncomment this line
}

\usepackage{graphicx} % Allows including images
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables

\begin{document}

\begin{frame}
\frametitle{RQ's and contribution}

\textbf{Research questions}

\begin{itemize}
\item Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua
\item Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua? 

\vspace{0.5cm
\hspace{-0.7cm}\textbf{Contribution}
}
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
\end{itemize}
\end{frame}

\end{document}

Answer 1

无需猜测任何手动空间，我会执行以下操作：

\documentclass{beamer}
\usepackage[backend=bibtex,style=authoryear]{biblatex}
\usepackage{mathtools}
%\usepackage{bm}
\mode<presentation> {
    \usepackage{tabularx,booktabs,dcolumn}
    \usetheme{Boadilla}
    \usepackage[style=authoryear]{biblatex}
    \renewcommand*{\nameyeardelim}{\addcomma\addspace}
    \setbeamertemplate{navigation symbols}{} % To remove the navigation symbols from the bottom of all slides uncomment this line
}

\begin{document}

\begin{frame}
\frametitle{RQ's and contribution}

\textbf{Research questions}
    \begin{itemize}
        \item Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua
        \item Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua? 
    \end{itemize}
