Thanks to all the people who've responded via e-mail, which made me realize an 
embarrassing  flaw in how  I've structured the contest that I must correct immediately,

i.e.,  to request that any respondents send their answers to me via e-mail, since posting 
them on the listservs would immediately short-circuit the contest!

BTW,  of the e-mail answers I've received, all 3 of the differences have been pointed out, 
but not by any single person, while several have pointed out things that I wasn't aware!!

Final answers will be posted on Thursday  morning.
