Statement: Should the education at all levels be offered only in vernacular medium ?
Arguments:
(I) Yes. This is the only way to enhance performance of the students.
(II) No. This will severely affect acquiring knowledge for want of good text books in vernacular medium.
Teaching in vernacular medium would surely make it easy for students to grasp. But the use of 'only' in argument I makes it invalid. Also, teaching in international language would open up more avenues for students - in procuring books and study material, in going abroad for studies as well as taking up jobs which require interaction with people of different nationalities. So, argument II holds strong.
