Guest  +  24170 Mon, 01 Mar 04 08:28 PM My question relates to the use of the words "on" and "upon" Is it correct to say "I relied on your good sense to solve the problem." or "I relied upon your good sense to solve the problem." I know one "lays a book on the table" but does one "rest an argument on a reliable source" or "upon a reliable source?" Thank you. Guest
