+		\item Gardenias must be immediately before Katydid.
+		\item Hibiscus must be somewhere before Katydid but cannot be the first photograph.
+		\item Irises and Lotus must be next to one another.
+		\item Magnolia must be one of the first three photographs.
+		\item Fence must be either first or seventh.
+	\end{itemize}
+
+	\problem{}
+	Which of the below could be a valid ordering?
+	\begin{itemize}
+		\item \texttt{FHGMKIL}
+		\item \texttt{HMGKILF}
+		\item \texttt{ILMHGKF} \thisone{}
+		\item \texttt{LMIHGKF}
+		\item \texttt{MFHGKLI}
+	\end{itemize}
+	\vfill
+
+	\problem{}
+	If Irises is immediately before Gardenias, which of the following could be true?
+	\begin{itemize}
+		\item Gardenias is fourth
+		\item Hibiscus is fourth
+		\item Irises is third
+		\item Lotus is second
+		\item Magnolia is third \thisone{}
+	\end{itemize}
+	\vfill
+
+	\problem{}
+	The ordering of the photographs is fully defined if...
+	\begin{itemize}
+		\item Gardenias is fourth
+		\item Hibiscus is second
+		\item Irises is second
+		\item Lotus is first \thisone{}
+		\item Magnolia is third
+	\end{itemize}
+
+	\vfill
+	\pagebreak
+
+	\problem{}
+	If Magnolia is second, what CANNOT be true?
+	\begin{itemize}
+		\item Hibiscus is third
+		\item Hibiscus is fourth \thisone{}
+		\item Hibiscus is fifth
+		\item Gardenias is fourth
+		\item Gardenias is sixth
+	\end{itemize}
+
+	\vfill
+
+	\problem{}
+	Katydid cannot be in which position?
+	\begin{itemize}
+		\item Third \thisone{}
+		\item Fourth
+		\item Fifth
+		\item Sixth
+		\item Seventh
+	\end{itemize}
+	\vfill
+
+	\problem{}
+	If Gardenias is fourth, what must be true?
+	\begin{itemize}
+		\item Fence is first \thisone{}
+		\item Hibiscus is third
+		\item Irises is seventh
+		\item Magnolia is first
+		\item Magnolia is second
+	\end{itemize}
+	\vfill
+
+	\problem{}
+	Which one of the following,
+	if substituted for the second condition,
+	would fully determine the arrangement of the photographs?
+
+	\begin{itemize}
+		\item If Fence is seventh, Hibiscus is second
+		\item Gardenias is somewhere after Hibiscus, and either Fence or Magnolia is first
+		\item Hibiscus must be somewhere between the first and sixth photographs
+		\item Unless Hibiscus is second, it must be somewhere between Magnolia and Gardenias \thisone{}
+		\item Katydid is somewhere after Hibiscus, which must be after Fence.
