Question and options

Directions: The question has a main statement followed by four statements, labelled P, Q, R, S. Choose the ordered pair of statements in which the first statement implies the second and the two statements are logically consistent with the main statement.
Main statement: Only in Africa, you can find the African Elephant
Statements:
P. You went to Africa
Q. You didn’t go to Africa
R. You saw the African Elephant
S. You didn’t see the African Elephant
Which ordered pair is correct?
  1. PR
  2. SQ
  3. PS
  4. QS

Answer and explanation

Correct answer: D - QS
"Only in Africa" means: if you saw the African elephant, you went to Africa. The contrapositive is: you did not go to Africa, so you did not see the elephant, which is Q then S, the valid ordered pair QS. PR affirms the consequent, and SQ and PS are invalid.
