Answers with Solution:
1).Some rights are false (I) àconversion àSome false are right (I) + All rights are wrong (A) = I + A = I = Some false are wrong (I). hence, conclusion I follows. Since there is no negative statement, conclusion II also follows.
Answer: e)
2).No toy is a treeàConversion àno tree is a toy(E) + Some toys are tough (I) = E + I = O*= Some tough are not trees (O*). Thus, there is a possibility that all trees are tough. Hence, conclusion I follows. Again, No toy is a tree (E) + All trees are trains (A) = E + A = O* = Some trains are not toys. So, there is no possibility that All trains are toys. Hence, conclusion Ii does not follow.
Answer: a)
3).Some books are boys (I) + All boys are baskets (A) = I + A = I = Some books are baskets. Hence, All baskets a being books is a possibility. Thus, conclusion I follows. Some books are boys àconversion àSome boys are books(I) + No book is a ball (E) = I + E = O = Some boys are not balls. Thus, All boys being balls is not a possibility. Hence, conclusion II does not follow.
Answer: a)
4).Some foods are forests (I) + All forests are frozen (A) = I + A = I = Some foods are frozen. So, there is a possibility that some foods are not frozen. Thus, conclusion I follows. Again, All forests are frozen (A) à conversion à Some frozen are forests (I). Thus, conclusion II also follows.
Answer: e)
5).Since there is no negative statement. All docks being airports is a possibility. Hence, conclusion I follows. Again, All ports are airports (A) + Some airports are harbours (I) = No conclusion. Hence, conclusion, II does not follow.
