Which among the following can be inferred from the passage?
Directions: Read the passage below and answer the question that follows:
THE DECADES–OLD proposal to link all of India's major rivers with one another was revived with much fanfare last year. Most political parties welcomed it then as a solution to the country's drinking water and irrigation problems. But it has not taken long for the proposal to come face to face with the hard reality of planning what will be the largest project ever taken up in India. A number of States, from Punjab in the north to Kerala in the south, have expressed their opposition to a transfer of river waters from their territory to other States. The latest example is the considerable anxiety in Kerala about including a link between the Pampa and the Achankovil (flowing through Kerala) and the Vaippar (in Tamil Nadu) in the proposed national river grid. This is only one of many reasons why the ambitious, many would say unrealistic. Schedules for execution of the project have already been thrown out of gear.
The high–level task force on the project, constituted in December 2002, was expected to prepare the schedule for completion of feasibility studies and estimate the cost of the project by the end of April this year. It was to then come up in June with the options for funding the project. It was also expected to convene a meeting in May/June of State Chief Ministers and obtain their agreement and cooperation. None of these deadlines has been met and there is no indication that these events will take place in the near future. This is not surprising, for while the interlinking proposal has been spoken about for decades, all the complex engineering, economic, environmental and social issues involved in the project have never been carefully studied. It is, therefore, not an easy task to draw up in a few months even the time lines for implementation. It will also be impossible to complete within a decade (as decreed by the Supreme Court) execution of a project that at first approximation is estimated to cost Rs. 5,60,000 crores, which is twice the size of India's gross domestic product at present. In fact, the one Government committee that did examine aspects of the proposal to some extent, the National Commission for an Integrated Water Resources Development Plan, was in 1999 ambivalent about the benefits of interlinking the country's rivers.
The drought of 2002 was the context in which the proposal to build a grid connecting India's rivers was revived. Before another drought leads to another round of active interest in the project, it is necessary to come up with answers to two broad sets of questions. The first question is, what will be the total costs and benefits of a river grid project in economic, environmental and social terms. The second will be, what are the different options to meet the future requirements of water and is the interlinking proposal the best among them. Answers to these questions will have to address issues in agricultural technology, patterns of water use, extraction of ground and surface water resources, efficiency in consumption of water in crop cultivation, resource mobilization, human displacement and changes in the environment. A plan on such a scale and of such complexity as the proposal to link the country's rivers can be taken up only after a range of such substa ntive issues are analyzed threadbare.
