Read the passage and answer the question:
The volume of information being gained daily shows how wickedly the salt tax has been designed. In order to prevent the use of salt that has not paid the tax which is at times even fourteen times its value, the Government destroys the salt it cannot sell profitably. Thus it taxes the nation's vital necessity; it prevents the public from manufacturing it and destroys what nature manufactures without effort. No adjective is strong enough for characterising this wicked dog-in- the-manger policy. From various sources I hear tales of such wanton destruction of the nation's property in all parts of India. Maunds if not tons of salt are said to be destroyed on the Konkan coast. The same tale comes from Dandi. Wherever there is likelihood of natural salt being taken away by the people living in the neighbourhood of such areas for their personal use, salt officers are posted for the sole purpose of carrying on destruction. Thus valuable national property is destroyed at national expense and salt taken out of the mouths of the people.

Vanaja and vasula are twin sisters who hail from the state of Kerala. They observed that children from her village were suffering from deformities due to prolonged use of pesticide contaminated river water and endosulphine spayed fruits and vegetables. Taking this into cognizance they both plan to start a firm which would promote organic farming in their village. In the beginning, the firm would be an association of two persons who would carry on the business as co-owners, would share profits and losses and would have unlimited liability. In order to avoid conflicts in future they would have a written agreement which will include all the classes relating to authority and responsibility of members, voting rights and roles and payment of members. The sisters will act as principal and agent for each other and for the firm. They discussed this proposal with the Block Development Officer (BDO). He was very appreciative of their efforts and suggested them to use a catchy slogan which would act as a powerful message to communicate to their cause. Taking clue from the suggestions made by the BDO, the sisters prepared a document which encompassed the relevant external and internal elements involved in starting a new venture. They approached BHIMA capitals Ltd with their proposal and presented a three-minute executive summary to awaken interest of potential funders. Quite impressed with the idea, the professional investors agreed to provide Private equity seed capital in return for minority shareholding.

To fight the British, leadership and organisation were required. For these the rebels sometimes turned to those who had been leaders before the British conquest. One of the first acts of the sepoys of Meerut was to rush to Delhi and appeal to the old Mughal emperor to accept the leadership of the revolt. This acceptance of leadership took its time in coming. Bahadur Shah's first reaction was one of the horror and rejection. It was only when some sepoys had moved into the Mughal court within the Red Fort that the old emperor agreed to be the nominal leader of the rebellion.

He established rules for spiritual conduct and interaction between inmates as well as between laypersons and the master. Sufi silsilas began to crystallise in different parts of the Islamic world around the twelfth century.
