Let $p,q$ be elementry statements and $\alpha,\beta,\gamma$ be statements. (sorry if this is the wrong translation).
is $p,q\Rightarrow \gamma$ tautology?
is $\alpha,\beta\Rightarrow \gamma$ tautology?
I think both are wrong since we have no information about the part in the red square below, for all we know $\gamma$ can be false with everything else. But it seems too easy so I'm doubting myself..
Note: $\Rightarrow$ means tautology, comma means $\wedge$.
