Solution 1

(i)The means of transportation and communication are called the lifelines of a nation and its economy because these are pre requisite for the economic development of the country. Transportation connects one part of the country to the other part. This helps in movement of goods and people from one region to the other. Industries cannot manufacture goods if the raw materials and finished goods are not transported from one place to the other. Agriculture also depends greatly on transportation as the grains needed to be transported to the market places.

Development of various means of communication has been one of the major factors which have facilitated the process of globalisation. Telecommunication systems and internet has helped in the development of trade and business activites.

 (ii) Trade between two or more countries is known as international trade. Advancement of international trade of a country is an index to its economic prosperity. In last fifteen years, international trade among various countries has increased significantly in the field of exchange of information and knowledge. Export and import of commodities and goods has been superseded by the exchange of information, knowledge and technology.

India has trade relations with most of the countries in the world. Her share of international trade has been on an increase in last few years.
