The second step of the answer parsing pipeline.
Once the answer is processed (which is the first step), the validity evaluator object determines whether the latter is considered as 'valid' formatwise. The fact that a given answer is valid does not imply that it's correct. The evaluation of the correctness of an answer is determined by the third and last step of the parsing pipeline, under the condition that the answer passes the validity check
