I think you're right. But as someone else pointed out, it's fair to assume
that the question was specifically conerned with x86 architecture, where
yes, 32-bit OSen will run just fine on the new 64-bit CPUs.
Intel had this crazy idea that they could push a new architecture and
instruction set for the server world (Itanium), and de-emphasize the x86
architecture in this market. Then AMD came out with 64-bit extensions with
complete backward compatability, forcing Intel to re-evaluate what they
were doing. It was quite amusing. :)
