Q. Consider the following statements:

1. The quality of the roads varies greatly between developed and developing countries.
2. The highest road density and the highest number of vehicles are registered in Europe.
3. In developed countries good quality roads are universal.

Which of the above is / are correct?
Answer: Only 1 and 3
Notes: The quality of the roads varies greatly between developed and developing countries because road construction and maintenance require heavy expenditure. In developed countries good quality roads are universal and provide long-distance links in the form of motorways, autobahns (Germany), and inter-state highways for speedy movement. The world's total motorable road length is only about 15 million km, of which North America accounts for 33 per cent. The highest road density and the highest number of vehicles are registered in this continent compared to Western Europe.
