# [OS X TeX] Unwanted blank page

I am writing a textbook in which there is an exercise section in each
chapter.
I have
\chapter
\section(Lecture}
\section{Exercises}
\begin{exercise}
\end{exercise}
etc
and all is well as the exercises are numbered (chapter #, exercise #)
So far, so good.

For practical reasons, this time, I want to hand out the exercises in
class, as I go.

I cut and pasted the exercises into another file, HomeWork_01 which
after the same preamble now reads:

\noindent{\Large \textsc{Math} \textbf{016} HomeWork 01}
\hspace{35mm}

12/29/2005

\begin{exercise}
\end{exercise}
etc

Problem 1. Now, of course, the exercises are numbered (0, exercise #).
So, I thought that I would just change the file to

\noindent{\Large \textsc{Math} \textbf{016} HomeWork 01}
\hspace{35mm}
Schremmer
12/29/2005

\setcounter{chapter}{0}
\chapter{}

\begin{exercise}
\end{exercise}
etc

The exercises are now properly numbered, (1, exercise #) and I don't
care about the Chapter 1 title.

The trouble is that on page 1 there is just the heading and then there
is a blank page and the exercises start on page 3.

Question: How do I get rid of all that un-ecological space? (As far as I
can see, Companion2ed explains only how to add blank space!)

Problem 2. In the text book, where the exercises were, I now have:

\section{Exercises}
%\include{016-HomeWork_02}
%Reminder: When actually including, change project root in
016-HomeWork_02 to 016-Arithmetic.tex
To be handed out in class.

Because I am going to have 24 chapters, what I would like, of course, is
code for changing mode without having to do all these changes
manually—at the considerable risk of botching things. Using %!TEX root =
../Main.tex should make it doable but this way beyond my capability.

What made me think of this being feasible is the responses I got on this
list about "How to comment out includegraphics?"
