Statements: 1. All clouds are rain. 2. All rain is water. Conclusions: I. All water is clouds. II. All clouds are water. Which conclusion(s) logically follow? MCQ with Answer and Explanation
Statements:
1. All clouds are rain.
2. All rain is water.
Conclusions:
I. All water is clouds.
II. All clouds are water.
Which conclusion(s) logically follow?
A. Neither I nor II follows
B. Only conclusion II follows
C. Only conclusion I follows
D. Both I and II follow
Answer: Option B
Solution (By JKSSB Mock Tests)
A implies B, and B implies C. Therefore, A implies C (All clouds are water). Conclusion I is a reverse implication, which is invalid.
Statement: Those hilly areas will be declared backward where forest area does not exist.
Conclusions:
I. Hilly forest areas are not backward.
II. In backward areas hills are without forest.
Explanation:
Conclusion I follows: if a hilly area lacks forest, it is declared backward; therefore, hilly areas with forest are not declared backward. Conclusion II does not follow because the statement only defines a condition for declaring backwardness, not that all backward areas are hilly and without forest.
