\item \lect Use the DPLL algorithm with \textit{Boolean Constrain Propagation} and \textit{Pure Literals} (\emph{without} clause learning) to determine whether or not the set of clauses given is satisfiable. Decide variables in alphabetical order starting with the \textit{positive} phase. If the set of clauses resulted in \texttt{SAT}, give a satisfying model.
