After looking the question over some more, I can see why the answers were written out the way they were. The GO statements were put in there to separate the pieces to be run and even though it cannot be executed exactly as it is written, it is overall correct and there isn't a better way to state it without writing "execute sp_configure... then execute RECONFIGURE". And it is true that configuring the option is not the same as enabling it since one could not use CLR until the reconfigure was performed.

Thanks,
