Difficulty: Easy
Choose an option
-
AOnly Conclusion I follows
-
BOnly Conclusion II follows
-
CBoth Conclusions I and II follow
-
DNeither Conclusion I nor II follows
Answer
Correct Answer: Only Conclusion I follows
Explanation
Given data
- All buildings ⊆ chalks.
- No chalk ∩ toffee ≠ ∅ (i.e., chalks and toffee are disjoint).
Reasoning If every building is a chalk and chalks have no overlap with toffee, then buildings cannot be toffee. Thus I follows. "All chalks are buildings" is the converse of the first statement and does not follow.
Final Answer Only Conclusion I follows
