Rearrange the following six sentence (1), (2), (3), (4), (5) and (6) in the proper sequence to form a meaningful paragraph ; then answer the questions given below them.
1. There are a number of items in the atomic energy programme which are being made indigenously.
2. Given the overall energy situation in India, the use of nuclear power in some measure is inescapable even while thermal and hydrogen power continue to be the dominant elements.
3. However. commercial aspects of exploiting nuclear capabilities, especially for power-generation programmes, have been recently given high priority.
4. Atomic energy programmes have been subject to serve restrictions for very obvious reasons as the Department of Atomic Energy is becoming self-reliant in areas in which only a few countries have such capability.
5. Even to meet these nuclear power requirements, India critically requires a commercial level power-generation capability with its commensurate safety and nuclear waste management arrangements
6. Thus, in the Indian context energy security is also crucial, perhaps much more than it is for the U.S.A. because India imports a good part of its crude oil requirements, paying for it with precious foreign exchange.
