Answers
Explanation:
step towards progress for early humans in the following ways: 1. Transportation from one place to another became faster and easier.
Though often thought of as one of the earliest inventions, the wheel actually arrived after the invention of agriculture, boats, woven cloth, and pottery. ... During the transition between the Neolithic and the Bronze Age, the very earliest wheels were made of wood, with a hole in the core for the axle.
Transportation wasn't as advanced. Since they didn't have cars back then, people mainly traveled on foot, horses, mules, or carts. However, traveling by water was a lot more efficient since there weren't any roads yet either. Medieval boats were made of wood and most were powered by wind.

The metro system is operated by Delhi Metro Rail Corporation (DMRC), a public sector company established by the Government of India and the Government of Delhi in March 1995.
one of the most cheap modes of transport in India, as it takes advantage of natural track and does not require huge capital investment in construction and maintenance except in the case of canals. ... India has 14500 km of inland waterways. Out of which only 5685 km are navigable by mechanized vessels.
