Statements : Some houses are offices. Some offices are schools. Conclusions : I. Some schools are houses. II. Some offices are houses. III. No house is school. IV. Some schools are offices.
A.
Only II and III follow
B.
Only I and IV follow
C.
Only either III or IV, and I follow
D.
Only II and IV and either I or III follow.
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Since both the premises are particular, no definite conclusion follows. However, I and III involve only the extreme terms and form a complementary pair. So, either I or III follows. II is the converse of the first premise while IV is the converse of the second premise. Thus, both of them hold.
