Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under sea­bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.

The time taken for the marine deposits to harden into rocks is

The conclusion of World Trade Organization’s 11th biennial ministerial conference at Buenos Aires was worrisome. From an Indian standpoint, there was no loss as status quo continues in the most important issue: the right to continue the food security programme by using support prices. But the inability of the negotiators to reach even one substantive outcome suggests that WTO’s efficacy is under question. As a 164-country multilateral organisation dedicated to crafting rules of trade through consensus, WTO represents the optimal bet for developing countries such as India. Strengthening WTO is in India’s best interest.

Perhaps the biggest threat to WTO’s efficacy today is the attitude of the US. The world’s largest economy appears to have lost faith in the organisation and has begun to undermine one of its most successful segments, the dispute redressal mechanism. This is significant as the US has been directly involved in nearly half of all cases brought to WTO. Separately, large groups of countries decided to pursue negotiations on e-commerce, investment facilitation and removal of trade obstacles for medium and small scale industries. By itself this should not weaken WTO. But it comes at a time when there is growing frustration with gridlock at WTO.

India did well to defend its position on its food security programme. The envisaged reform package which will see a greater use of direct cash transfers to beneficiaries will be in sync with what developed countries do. But it’s important for India to enhance its efforts to reinvigorate WTO. In this context, India’s plan to organise a meeting of some countries early next year is a step in the right direction. WTO represents the best available platform to accommodate interests of a diverse set of nations. Therefore, India should be at the forefront of moves to fortify it.

Which of the following is the most successful segments of the WTO mentioned in the passage?
