Question 9
MediumOriginal questionStatement: The sports secretary of Ranipur announces: "The inter-college football final will be played on Saturday if the ground is dry, and on Sunday if it is not."
Conclusions:
I. The final will be played on Saturday.
II. The final will be played on Sunday.
Which conclusions follow?
Show the answer and explanation
Correct answer: C
Explanation
I does not follow on its own: the final is on Saturday only if the ground is dry, and the statement does not say whether it will be.
II does not follow on its own either: the final is on Sunday only if the ground is not dry.
But the ground is either dry or not dry, so one of the two must happen. I and II cannot both be true, and one of them has to be. Either I or II follows.
Worth noting
Use "Either I or II" only when neither item follows alone, the two cannot both be true, and the statement guarantees that one of them is.
