\item \lect In the following list, tick all statements that correctly describe the meaning of the term \textit{Satisfiability Modulo Theories}.

\begin{itemize}
\item[$\square$] A formula is \textit{satisfiable modulo a theory} if all models that satisfy the axioms of the theory also satisfy the formula.
\item[$\square$] \textit{Satisfiability Modulo Theories} refers to the fact that in sufficiently complex theories, some statements can neither be proven nor disproven. Thus, they are satisfiable, but not valid.
\item[$\square$] \textit{Satisfiability Modulo Theories} means that for a consistent theory there always exists a model which satisfies all the axioms of the theory. Thus, the theory is \textit{satisfiable}.
\item[$\square$] It is possible to find axioms that characterize the intuitive meaning of the arithmetic \textit{modulo} operator. The resulting \textit{theory} is \textit{satisfiable}.
\end{itemize}
