Statement: Education is the most powerful weapon. Conclusions: I. Education can change the world. II. Weapons can destroy things.
A. Only II follows
B. Both I and II follow
C. Only I follows
D. Neither I nor II follows
Answer: Option C
Solution (By JKExamLibrary)
The statement implies education has great power to effect change, so I follows. II is not directly implied; the metaphor is about power, not literal weapons.
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?
Explanation:
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.
Statement: Price of each consumer product has increased at least by 8%.
Conclusions:
I. Prices of some commodities has not increased.
II. There is not a single commodity in consumer products whose price has not increased.
Explanation:
Conclusion II directly restates the given information: every consumer product's price has increased. Conclusion I contradicts the statement, so it does not follow.
Statements:
1. All cars are vehicles.
2. Some vehicles are not machines.
Conclusions:
I. Some cars are not machines.
II. All vehicles are cars.
Which conclusion(s) logically follow?
Explanation:
We know all cars are vehicles, but the vehicles that are not machines might be entirely outside the 'cars' circle. Therefore, Conclusion I is not definite. Conclusion II is a reverse of an 'All' statement, which is generally invalid. Neither follows.
