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: You can find Chinese toys only in China
Statements:
P. I didn’t find any Chinese Toys
Q. I found Chinese Toys
R. I went to the fair
S. I didn’t go to China
Which ordered pair is correct?
  1. SR
  2. RQ
  3. RP
  4. SP

Answer and explanation

Correct answer: D - SP
"You can find Chinese toys only in China" means: if I found Chinese toys, I went to China. The valid inference is the contrapositive: I did not go to China (S), so I did not find any Chinese toys (P), the ordered pair SP. SR, RQ and RP bring in the unrelated fair.
