<u>Statements :</u> Some houses are offices. Some offices are schools.<br><br><u>Conclusions :</u><br>I. Some schools are houses.<br>II. Some offices are houses.<br>III. No house is school.<br>IV. Some schools are offices.

Correct Answer: Only II and IV and either I or III follow.
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.
