Statement:
The meteorology department has predicted heavy rainfall and thunderstorms for the next 48 hours.
Conclusions:
I. Citizens should carry umbrellas when going out.
II. Flights might get delayed or cancelled.
Which conclusion(s) logically follow?
A. Only conclusion I follows
B. Only conclusion II follows
C. Both I and II follow
D. Neither I nor II follows
Answer: Option C
Solution (By JKExamLibrary)
Both conclusions are logical inferences based on the prediction of severe weather. Carrying an umbrella is a logical precaution, and severe thunderstorms logically impact aviation schedules.
Statements:
1. Some phones are smart.
2. No smart thing is cheap.
Conclusions:
I. Some phones are not cheap.
II. No phone is cheap.
Which conclusion(s) logically follow?
Explanation:
The phones that are smart cannot be cheap (since no smart thing is cheap). Therefore, at least some phones are definitely not cheap (Conclusion I). We don't know about the phones that are not smart, so II does not follow.
Statement:
If India wins the match, a public holiday will be declared.
Conclusions:
I. India won the match, so a public holiday was declared.
II. A public holiday was declared, so India must have won the match.
Which conclusion(s) logically follow from the given rule?
Explanation:
The statement represents 'If A then B' (A implies B). Therefore, if A happens, B definitely happens (Conclusion I). However, B could happen for other reasons (e.g., a festival), so B does not necessarily imply A (Conclusion II is a logical fallacy known as affirming the consequent).
