SUMMARY
A totally ordered set, when partitioned into noncrossing blocks, maintains the total order within each block. This inheritance of total order is a direct consequence of the definition of total order. To prove that each block of a noncrossing partition is totally ordered, one must apply the definition of total order to the subset formed by each block. The discussion confirms that if X is totally ordered and A is a subset of X, then A is also totally ordered.
