Yeah, not well presented, forces one to make assumptions which may not be right. The only pies mentioned are "fruit pies", "apple pie" and "blueberry pie". Apple is a fruit, but blackberry isn't ...
Mrs. Bly could not have won the blackberry, because it isn't a fruit. Saying that Mrs. Wig's blueberry pie is better than her other pies does NOT mean she won in that category - it all depends on the level of competition in each category.
There is not enough to solve, but you could guess:
Mrs Bly: Apple
Mrs. Wig: Blueberry
Mrs. Jones: Chicken and Mushroom (why not
)
