What castle did Thomas Gregory inherit?

[jacktang]

Hello,

I am new to dspy and play the demos one by one, it looks so fun! In the Intro Notebook, I changed the question to "What castle did Thomas Gregory inherit?", and "Thomas Gregory" is a fake name, I expected the answer is "not mentioned". But the answer still is "Kinnairdy Castle", I wonder is there any solution to fix it? Thanks!
