[OS X TeX] Unwanted blank page

[Alain Schremmer]

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}
    Schremmer
    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?"
