Dear Mr. Alan

As you told that in question#.3 Start off means(This is usually used to indicate the start/beginning of a trip or a journey).

but in question#.9 (Who would like to "start off" the debate?)

what start off means here although Mr. Torsten explain well but it is still confusing me.

waiting for your reply

Thanks & Regards
