 Lois Lane knows that \(A\) (Clark Kent loves the Guggenheim Museum) if and only if she knows that \(B\) (“Clark Kent loves the Guggenheim Museum” is true) (surely Lois knows how truth works!). On the other hand, she knows that \(C\) (Clark Kent is in New York), but she doesn’t know that \(D\) (Superman, too, is), for she is not aware that Superman is Clark Kent.
