Ask Marilyn ® by Marilyn vos Savant is a column in Parade Magazine, published by PARADE, 711 Third Avenue, New York, NY 10017, USA. According to Parade, Marilyn vos Savant is listed in the "Guinness Book of World Records Hall of Fame" for "Highest IQ."
In Marilyn's Parade Magazine column of November 29, 1998, she claims that sporange rhymes with orange.
Neither of the two pronunciations of SPORANGE in Webster's Third New International Dictionary would qualify as a rhyme, in my opinion!(The ending sounds of sporange and orange are similar, but not identical.)
