Page breaking problem

[Helin Gai <hg9@duke.edu>]

Hi, I'm new to ConTeXt and I'm preparing a document for my own  
reference. The source code is below. I came across a few weird  
issues: 1) I don't quite understand why the page break occurs on  
pages 4 and 6; 2) Why are the first two items in the table of  
contents in red instead of green?

Thanks so much!!
