Q3 Answer the following questions in about 120 words.
(i) Why are the means of transportation and communication called the lifelines of a nation
and its economy?
(ii) Write a note on the changing nature of the international trade in the last fteen years.

Answer. (i) The means of transportation and communication are called the lifelines of a nation
and its economy because they are the preconditions for progress and development. Goods and
services cannot move on their own from supply houses to demand locales. This necessitates
the need for transportation. Thus, a country’s economy depends not only on the production
and sale of goods and services, but on their transport as well. Globalisation has been possible

on account of easier and fast-developing communication channels between the countries of
the world. Hence, it complements trade as well as transport. India is well-connected with the
rest of the world due to these two things—transport and communication, which have
contributed vastly to the development of our national economy. They have also added
extensively to growing amenities and facilities improving our lifestyles.

(ii) The changing nature of the international trade for India, in the last fteen years, has been
impressive. Exchange of information and knowledge has surpassed exchange of goods and
commodities. Through its advanced software knowledge and excellence in the eld of
information technology, India has emerged as a viable contender at the international level and
is earning huge amounts of foreign exchange through the same. Tourism too has added to
India’s upgraded position in international trade. In 2004, there was a 23.5% increase in foreign
tourist arrivals as against the number in 2003. Thus, international trade for India has
undergone a cognisable change in the past fteen years.
