Question from UPSC Prelims 2021 CSAT Paper
Explanation :
Logical Conclusions from Cat, Almirah, Chair Statement
Conclusion-I: Certainly some almirahs are tables. This conclusion follows logically from the statement because if some almirahs are chairs and all chairs are tables, then it follows that some almirahs must also be tables.
Conclusion-II: Some cats may not be chairs. This conclusion also follows logically from the statement because while it is stated that some cats are almirahs and some almirahs are chairs, there is no information given about whether all cats are almirahs or whether all almirahs are chairs. Therefore it is possible that some cats may not be chairs.
So both Conclusion-I and Conclusion-II logically follow from the given statement and the correct answer to this question is © Both Conclusion-I and Conclusion-II.
