d More sophisticated engines
4. A steam engine developed by James Watt (1736-1819) is not revolutionary as the world of energy production, but rather the development of iron and steam villages. It is necessary to develop the technology mentioned in the text.
a Streamlined communication and transport networks, contributing to other industrial sectors.
b Led to the reduction of the scale of production in industries and reduced working hours.
c Expanded scientific knowledge, but brought economic losses to England.
d Was restricted to the areas of the factories, having little influence in the daily life of the populations.
