If Antonia finished before Elizabeth, then Elizabeth finished
later than Antonia.
Catherine finished after Antonia, but we do not know how Catherine
finished compared to Elizabeth.
If Denise finished after Brenda, Brenda was not the last, but
we cannot be certain how Denise did in comparison to the others. Denise
may have been the last.
Any one of Catherine, Elizabeth and Denise could have finished last. We lack
the necessary information to find out who actually did finish last.
George B. Durham [gdurha1@erols.com] wasn't fooled by Minus' sneaky question:
Catherine, Elizabeth or Denise finished last. Antonia and Brenda couldn't have because it said that they definately had someone finish after them.
