Well these aren't about the content of the questions so much as translating them into formal logical notation
Yeah, I know. I was just curious whether that was actually true, though it almost certainly isn't if we consider "if and only if" to require 100% correlation with no acceptable error value. An acceptable error value of "within one year", maybe, though I think Costa Rica does tend to pride itself on being more politically stable than its neighbors, even though it has indeed at some point defaulted on its debts many decades ago.
Anyway yeah I know it's not about the truth value but the topic just happened to be something I'm vaguely familiar with and so I thought about it for trivia's sake.

all those other ones seem far more annoying to write out
27. ( J ⇒ ¬M ) ⇒ ( ¬H ⇒ ¬( B ∧ N )) (I'm interpreting 'x only on the assumption of y' as ¬x ⇒ ¬y)
28. (( A ∧ B ) ∨ ( C ∧ D )) ⇒ ¬(( E ∧ F ) ∨ ( G ∧ H ))
29. D ⇔ ¬Q
30. ( N ⇔ C ) ⇒ ( B ⇒ A ) (I'm interpreting 'x exactly on the condition of y' as ¬y ⇒ ¬x)
