A statement is given, followed by two conclusions numbered I and II. Taking the statement to be true, decide which of the conclusions logically follows from it.
Statement: The city museum is closed on every Monday and on every national holiday. Today the museum is open.
Conclusions:
I. Today is a Sunday.
II. Today is not a national holiday.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Only conclusion II follows
A conclusion follows when the statement, taken as true, leads to it in every possible case; if even one case fits the statement but not the conclusion, it does not follow.
I. Today is a Sunday. Does not follow. The museum being open rules out only Monday; today could be any of the other six days, for example a Wednesday that is not a holiday.
II. Today is not a national holiday. Follows. On every national holiday the museum is closed. It is open today, so today cannot be a national holiday.
