Nice test. I tested it with llama.cpp and the 20b model. He got the answer correct at first try on my side. The internal/thinking dialogue is fun to read - it could be my own inner dialogue ;)
``` > "Bobs dad has five daughters, Lala, Lele, Lili, Lolo and ??? <|channel|>analysis<|message|>The question: "Bobs dad has five daughters, Lala, Lele, Lili, Lolo and ???". It's a common riddle. The answer is Bob? Actually "Bob's dad has five daughters: Lala, Lele, Lili, Lolo and..." The riddle is to trick: it's "Bob" himself is a daughter? Wait Bob's dad has five daughters: Lala, Lele, Lili, Lolo, and Bob? But Bob is a name often male. But the riddle says Bob's dad. So Bob is a person who has a dad, and that dad has five daughters. But Bob could be the fifth daughter? That would be weird: Bob is likely the name of the fifth daughter. So answer: Bob. But sometimes the answer is "Lulu" or "Bob's sister"? Let's think. The riddle is a trick: It's "Bobs dad has five d aughters: Lala, Lele, Lili, Lolo, and ... Bob." Because the riddle begins with "Bobs dad has five daughters" implying Bob is one of the daughters. So the missing daughter is Bob. So answer: "Bob".
Thus answer: Bob. But sometimes the riddle goes "Bob's dad has five daughters, Lala, Lele, Lili, Lolo, and ... Who is the fifth?" The answer: Bob (the name of the person speaking, "Bobs"). But in riddle it's "Bobs dad has five daughters , Lala, Lele, Lili, Lolo and ???". The missing name is "Bob." So answer: Bob.
Thus the answer: Bob. Or maybe it's "Boba"? But no.
Hence answer: Bob.
We'll answer accordingly.<|start|>assistant<|channel|>final<|message|>The missing daughter is *Bob*. The riddle starts with “Bob’s dad …” so Bob himself is the fifth daughter. ```
