Which one of the following sentences is a logical consequence of some others?
Mark those which are in your set M of sentences by writing a "1" in the first row.
Then you can get the truth table, but also only those rows of the truth table
(those assignments) where all our sentences in M are true. Then you only have to check
whether under these assumptions the considered statement is also true in each row shown.
For instances, statment # 5 is a consequence of statments #1,2,3,
but statement #4 is not.
