The situation when acceptability of an answer depends on aggregation of e.g. three criteria and having first fulfilled by an object b, second by c and the third by d what follows about acceptability of an object a. Similarities and fuzzy predicate logic with equality axioms. Iteration of the database under the Tp operator gives solution which is sound and complete. The case when similarity is unknown. Probabilistic argument for a construction of a similarity from fuzzy sets representing above criteria.
