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.

Read the given passage carefully and answer the following question :
Depending on the mode of occurence and the nature of the ore, mining is of two types : surface and underground mining. The surface mining is also known as open-cast mining is the easiest and the cheapest way of mining minerals that occur close to the surface. Overhead costs such as safety precaution and equipment is relatively low in this method. The output is both large and rapid.
When the ore lies deep below the surface, underground mining method (shaft method) has to be used. In this method, vertical shafts have to be sunk, from where underground galleries radiate to reach the minerals. Minerals are extracted and transported to the surface through these passages. It requires specially designed lifts, drills, haulage vehicles, ventilation system for safety and efficient movement of people and material. This method is risky. Poisonous gases, fires, floods and caving in lead to fatal accidents.
The developed economies are retreating from mining, processing and refining stages of production due to high labour costs, while the developing countries with large labour force and striving for higher standard of living are becoming more important. Several countries of Africa and few of south America and Asia have over fifty per cent of the earnings from minerals alone.
