premise: Fido Dido is a cartoon character created by Joanna Ferrone and Sue Rose. Rose first developed the character in 1985, on a napkin in a restaurant. They later stenciled Fido on T-shirts with the credo: "Fido is for Fido, Fido is against no one". These T-shirts became very popular in New York.
hypothesis: Fido Dido was first developed in the 20th century.
reason: It's definitely correct because it was developed in 1985, which is in the 20th century. I don't think the system understands what it means for something to be in the 20th century, so it always answers that type of question incorrectly.
