 We want to find 1-simplices which connect $K$ and $K'$.
 We might hope that $K$ and $K'$ have a common refinement, but this is not necessarily
 the case.
-(Consider the $x$-axis and the graph of $y = x^2\sin(1/x)$ in $\r^2$.)
+(Consider the $x$-axis and the graph of $y = x^2\sin(1/x)$ in $\r^2$.) \scott{Why the $x^2$ here?}
 However, we {\it can} find another decomposition $L$ such that $L$ shares common
 refinements with both $K$ and $K'$.
 Let $KL$ and $K'L$ denote these two refinements.
