Sulakshana is angry because she does not believe that the elections will change anything in her hilltop village, where tribal customs have locked women in a time warp for generations. This is a growing sentiment among woman in Ribba, about 250 km north east of Himachal Pradesh, capital of Simla.

Women in tribal kinnawr district have nothing. They still cannot inherit property. The daughter can use the family estate but not sell it. Even occupation is unequally divided - women do most of the work in orchards and farm and at home. The men take the fruits and almonds to the market. Now a budding feminist movement is hoping to shake things up. Young educated woman who studied in colleges are coming back with broader view of life.

Zango Debi says" we need to change our laws in favour of woman ". The problem is that the women are also very conservative and won't come forward. There is a wall of silent opposition from the men, ever educated ones. Sulakshana Negi planned to approach the President, Pratibha Patil to ask for laws to be amended. She and many other women want to devote their life to helping woman find a place in the society.

1. Why is sulakshana Negi angry ? 2. What is the plight of the women in kinnawr? 3. What work do men and women do ? 4. What changes would the educated girls bring? 5. According to you, how can we change the attitude that men have

towards women in today's society? 6. Write the meaning of the following words.

i) wall of silence ii) conservative.

7.Give a suitable title to the above passage.
