\section{First exercise}
Your job in this, and subsequent exercises, is simply to reproduce
these pages using \LaTeX. You should need no more than the basics
explained in \emph{Essential \LaTeX}. This section exercises your
understanding of sectioning commands, lists, and special characters.
Don't worry if you don't wan't to tackle it all at once --- do it bit
by bit. Examine your output carefully --- there are a few little
points you might not have noticed (like the length of the
parenthetical dash in this sentence!).

\begin{enumerate}
\item I have opened an account with Bradford \& Bingley; they offer
5.5\% interest if I keep more than \pounds 50 in the account.
\item The number of female students in computer science in the
universities is well below 40\%
\item `N\~{a}o sou o \'{u}nico a olhar o c\'{e}u'
\item Week\_Days = \{monday, tuesday, wednesday, thursday, friday, saturday,
sunday\}
\item \#Week\_Days = 7
\item ``Amanh\~{a} \'{e} o anivers\'{a}rio da revolu\c{c}\~{a}o''
\item He gave four reasons for accepting that proposal:
\begin{enumerate}
\item it was \emph{original}
\item it was \emph{well founded}
\item it was \emph{relevant}
\item it was \emph{a challenge}
\end{enumerate} 
\item The discussion was focused on the following points:
\begin{itemize}
\item clarity of exposure
\item originality
\begin{itemize}
\item for the specific aims
\item for the overall project
\end{itemize}
\item theoretical soundness
\end{itemize}
\end{enumerate}

Those illustrated (IR I--IV) are grouped as follows:

\begin{description}
\item[Fig 86] IR I.
\textbf{Tools,} including the `spatula'
(possibly votive, see below), a
reaping-hook, three possible styli, and possible tongs.

\textbf{Weapons,} including spear- and arrow-heads.
20 knives, and a knife sheath frame (for discussion of knife types,
see below).

\textbf{Building fittings,} including door hanger sockets, a door stud,
a hinge, and part of a possible lock plate.

\item[Fig 87] IR II. Animal and harness fittings; boot nails,
plates or studs, buckle
frames, brooches and pins, and other fittings of uncertain purpose.
\item[Fig 88] IR III. Buckle pins, balance arm, pins and rods, strips,
bolt heads and ferrules.
\item[Fig 89] IR IV. Nails in ten types.

\section{Development}
In this section we will develop both the methodology of Prof.\ Knuth
and how it can be applied. 
\subsection{The methodology}
The methodology proposed consists of the following steps:
\begin{enumerate}
\item Step 1
\item Step 2
\item Step 3
\end{enumerate}
\subsection{Applications}
Call me Ishmael.  Some years ago --- never mind how long precisely ---
having little or no money in my purse, and nothing particular to
interest me on shore, I thought I would sail about a little and see
the watery part of the world.  It is a way I have of driving off the
spleen, and regulating the circulation.  Whenever I find myself
growing grim about the mouth; whenever it is a damp, drizzly November
in my soul; whenever I find myself involuntarily pausing before coffin
warehouses, and bringing up the rear of every funeral I meet; and
especially whenever my hypos get such an upper hand of me, that it
requires a strong moral principle to prevent me from deliberately
stepping into the street, and methodically knocking people's hats
off --- then, I account it high time to get to sea as soon as I can.  
Two case studies will be used to apply the proposed methodology
\subsubsection{Case Study I}

\section{Conclusions}

This
is my substitute for pistol and ball.  With a philosophical flourish
Cato throws himself upon his sword; I quietly take to the ship.
