\begin{itemize}
\item Consider (example taken from p.~11 EDJRS) the scanning of a set

\begin{description}
\item{$\bullet\ n_{\rm\, tot}$} --- pictures with some property of
interest
\item{$\bullet\ n(A)$} --- number found by an undergraduate during
finals week
\item{$\bullet\ n(B)$} --- number found by a graduate student working on
a theory in 26 dimensions
\end{description}

\item Here, $A$:\ \ Scan Number One

$\phantom{Here,} B$:\ \ Scan Number Two

\item We can tag members of $C=AB$ ($A$ and $B$).
