+		\item[Question:] \textbf{\emph{Why should peanuts be banned on board aircraft?}}
+		\item[($a_1$):] \emph{Peanut reactions can be life threatening. An individual doesn't have to consume the product to have a life threatening reaction. They can have contact or inhalation reactions.}
+		\item[($a_2$):] \emph{Providing buffer zones to avoid contact with peanuts is a thoughtful gesture. But from a practical point of view, it does not work.}
+		\item[($a_3$):] \emph{With so many food choices available, why are peanuts a necessary choice?}
+		\item[($a_4$):] \emph{Restricting the ban of peanut products to certain flights is not enough.}
