Question

how was kabber different from the other students in the story indias heroes

Answer 1

He, for his assignment was a little different from that of other students. It was not about famous personalities, nor did it focus on a particular proffession.Every student spoke about only one idol or follower. But he spoke about not only about one people but many people at the same time. The other students spoke about criketer, social worker or a pilot.
But Kabeer spoke about the unsung heroes of November 2008 terrorists attacks on mumbai.
Therefore kabeer himself, who was an average student, also becomes the hero of his class, because of his hard work and the confidence he has shown in doing something different from his classmates.
