            1.   (a) Since both the premises are universal  and   4.   (e)  ‘Every’ is equivalent to ‘All’. Thus, since both
                affirmative, the conclusion must be universal         the premises are universal and affirmative, the
                affirmative. However, conclusion II, being an A-type   conclusion must be universal affirmative and should
                proposition,  distributes the term ‘goats’. Since     not contain the middle term. So, I follows. II is the
                the term ‘goats’ is distributed in II, ithout being   converse of the second premise and thus it also
                distributed in any of the premises, so conclusion II   holds.
                cannot follow. Thus , only I follows.

                     Hence , Only I follows.                          even  once in the premises, no definite  conclusion
            2.   (b) Since both the premises are universal  and       follows. However, I and II involve only the extreme
                affirmative, the conclusion must be universal         terms and form a complementary pair. So, either I or
                affirmative and should not contain the middle term.   II follows.
                So,  it follows that ‘All pens are houses’. II  is  the
                converse of this conclusion and so it holds. Since the   Tigers                   Tigers
                term ‘houses’. II is the converse of this conclusion
                and so it holds. Since the term ‘houses’ is distributed           Horses   or               Horses
                in I without being distributed in any of the premises,
                so I does not follow.

                even  once in the premises, no definite  conclusion
                follows. However, II  is the converse of the first
                premise and so it holds.
