Statement: If you work hard, you will pass. Conclusions: I. You passed, therefore you worked hard. II. You did not work hard, therefore you did not pass.
A. Only I follows
B. Both I and II follow
C. Neither I nor II follows
D. Only II follows
Answer: Option C
Solution (By JKExamLibrary)
This is a conditional statement. I is affirming the consequent (fallacy). II is denying the antecedent (fallacy). Neither follows logically.
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.
