Suppose The Mysterious Package<br>John received a mysterious package in the mail. It was addressed to him but had no return address. Inside the package was a key and a cryptic note that read, 'Find the lock that this key unlocks.' John was puzzled and spent days trying to figure out the meaning of the note and the purpose of the key.
Can we infer that "John immediately knew what the key was for"? Yes, no, or maybe?
