Read the passage and answer the questions:

Peace within the country and between nations have always been of great importance. Peace and order are to secure national and international progress and development. Global economies are coming closer today due to faster means of transport and communication. Economically, economies are becoming increasingly inter-dependeve. If peace is disturbed in one part of the world, it has adverse effect in other parts of the world as well. If the conflicts between different nations are not settled in time, they might culminate in a nuclear war destroying the whole world. It is, therefore, in our own interest that the world is free of conflicts. A country needs the help and co-operation of other countries for its scientific, industrial and economic development, especially in those fields where a nation is yet to achieve self-sufficiency. A nation should be keen on maintaining friendly relations with other countries. Such friendly relations foster international understanding. All nations should participate in the international conferences on issues like energy crisis, environmental imbalance, nuclear arms race, etc. A nation should always offer a helping hand to other nations affected by natural calamities such as famines, earthquakes, floods and so on.
