An individual \textbf{doesn't have to consume} the product to have a life threatening reaction. They can have \textbf{contact or inhalation reactions.}} \item[($a_2$):] \emph{Providing \textbf{buffer zones} to avoid contact with peanuts is a \textbf{thoughtful gesture}. But from a practical point of view, it does not work.} \item[($a_3$):] \emph{With so \textbf{many food choices} available, \textbf{why are peanuts a necessary choice?}} \item[($a_4$):] \emph{\textbf{Restricting} the ban of peanut products to certain flights is \textbf{not enough}.} \end{description} \begin{block}{Possible ranking} $a_1 > a_2 \geq a_3 > a_4$? \end{block} \end{frame} \subsection{About this work} \begin{frame} \frametitle{About this work} \textbf{This paper covers the following topics:} \begin{itemize} \item Follow-up of \cite{wachsmuth:2017a} \item Evaluation of methods for determining relevant arguments \begin{itemize} \item Analysis of PageRank \item Intuitive content- and knowledge-based methods \end{itemize} \end{itemize} \begin{block}{Results} \begin{itemize} \item PageRank is not entirely sufficient \item Better results with content- and knowledge-based methods \end{itemize} \end{block} \end{frame}
