NCERT Solution Class 10 - Social Science - CH3 : Democracy and Diversity


Q1: Some Dalit groups decided to participate in the UN Conference against racism in Durban in 2001, demanding the inclusion of caste in the agenda of this conference. Here are three reactions to this move:

Amandeep Kaur (a government official): Our Constitution declares caste discrimination to be illegal. If some caste discrimination continues, it is an internal matter. I am opposed to this being raised in an international forum. 

Oinam (a sociologist) : I am opposed to this because caste and race are not similar divisions. Caste is social division, while race is a biological one. Raising caste in this conference on racism would mean equating the two.

Ashok (a Dalit activist) : The argument about internal matter is  a way of preventing open discussion of oppression and discrimination. Race is not purely biological. It is as much a legal and sociological category as caste. Caste discrimination must be raised in this conference.

Which of the three opinions do you agree with most and why?

Answer: I agree with Ashok's views. We should not prevent people from an open discussion of oppression and discrimination just for the sake of internal state matter. We can't discriminate people and divide them based on intellectual grounds. We can't be a democratic nation and a free society, if there is oppression and discrimination in our society. Open debates is one of the indicator of a democratic society which values equality.


Q2: I met this group of girls from Pakistan and felt that I had more in common with them than many girls from other parts of my own country. Is this anti-national to feel so?

Answer: No. It is not anti-national to feel so.  It is quite common that people belong to different regions or nations can have common liking and interests. For example, the girls from Pakistan may like Hollywood movies, south Indian food and Thai food like any other girl from India.


Q3: A Cartoon like  this can be read by different people to mean different things. What does this  cartoon mean to you? How do other students in your class read this?

Answer: The giant in the cartoon is going to cut his black colour hand which is different from his other white hand. His small head reflects that he fails to realize that this stupid act would cripple him for life. It definitely reflects how a narrow minded society can harm itself by keeping a biased discrimination among its own people.
Other students in my class may have different opinions or perspectives.


Q3: Read these three poems by Dalit writers. Why do you think the poster is titled ‘Hidden Apartheid’?

Answer: These poems reflect that atrocities on Dalits and discrimination based on caste still exist in one way or other despite having laws to check such exploits.
