Directions: Each question has a main statement followed by four statements labelled A, B, C and D. Choose the ordered pair of statements where the first statement implies the second, and the two statements are logically consistent with the main statement.
Either the orangutan is not angry, or he frowns upon the world. A. The orangutan frowns upon the world. B. The orangutan is not angry. C. The orangutan does not frown upon the world. D. The orangutan is angry.
Explanation:
The main statement clearly states that if the orangutan (O) belongs to the set of not angry (NA), he cannot belong to the set of frowns (F). Also, O must belong to either of the two sets.
CB states that O is not F and is NA. And DA states that O is not NA and is F. Therefore, both CB and DA are logically valid.
