 - `intros`: Independent variables $V$ and hypotheses $\Phi$. $V=\{v_i\}_{i=1}^n$ is the set of variables independent to the queriable $a$. $\Phi = \{\phi_i\}_{i=1}^p$ is the set of propositions that depend on $V$ (whose all free variables are included in $V$), consisting of conditions that can be used to deduce the answer.
 - `outros`: Conclusions $\Psi = \{\psi_i\}_{i=1}^q$ is the set of propositions which depend on $V \cup \{a\}$, consisting of conclusions that should be satisfied.
 - `formal_answer`: The ground-truth answer in formal language (Lean 4).
 - `formal_answer_type`: The type of the ground-truth answer in formal language (Lean 4).
-- `metainfo`: Meta-information of the problem.
