Syllogism practice

From the above Venn diagram, we can say that conclusion I does not follow the given statements as some ‘novels’ are ‘short stories’ and all ‘short stories’ are inclusive of good, so some ‘goods’ are always ‘novels’.

From the above Venn diagram, we can say that conclusion II is possible but not definite, so conclusion II does not follow the given statements.

Hence, (d) is the correct answer.
