premise: Oh , Maria , I 've longed for years and years just to hear her sing once more .<br>It seems as if I MUST hear my little Joscelyn sing once again before I die .<br>I 've never had the chance before and I never will have it again .<br>Do please ask William to take me to Kensington . ''<br>`` Dear me , Aunty Nan , this is really childish , '' said Mrs. William , whisking her bowlful of berries into the pantry .<br>`` You must let other folks be the judge of what is best for you now .
hypothesis: Mrs. William was born in 1980. 
reason: There is no information in the context as to what years are involved, so logically it cannot be said for certain whether or not the person named was born in 1980.
