		\item[($a_1$):] \emph{Peanut reactions can be \textbf{life threatening}. 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}.}
