4.3 Problem 31 Let scientist(1) denote the statement "x is a scientist", and honest(1) denote the statement x is honest." Formalize the following sentences and indicate their corresponding formal type. 1. "No scientists are honest." 2. "All scientists are crooked." 3. "All scientists are honest." 4. "Some scientists are crooked." 5. "Some scientists are honest." 6. "No scientist is crooked." 7. "Some scientists are not crooked." 8. "Some scientists are not honest." Identify pairs that are contradictories, contraries, subcontraries, and pairs that support sub- alteration (clearly indicating superaltern and subaltern).
