Question : Comprehension:
Read the following passage and answer the questions given after it.
In the late 18th century the Industrial Revolution began to transform life in Britain. Until then, most people lived in the countryside and made their living from farming. By the mid-19th century, most people in Britain lived in towns and made their living from mining or manufacturing industries. In 1712 a man named Thomas Newcomen (1663-1729) made primitive steam engines for pumping water from mines. In 1769 James Watt (1736-1819) patented a more efficient steam engine. In 1785 his engine was adapted to driving machinery in a cotton factory. The use of steam engines to drive machines slowly transformed the industry. Meanwhile, during the 1700s Britain built up a great overseas empire. The North American colonies were lost after the War of Independence 1776-1783. On the other hand, after the Seven Years' War 1756-1763, Britain captured Canada and India. Britain also took Dominica, Grenada, St. Vincent and Tobago in the West Indies. In 1707 the Act of Union was passed. Scotland was united with England and Wales. England became part of Great Britain. Owning land was the main form of wealth in the 18th century. Political power and influence were in the hands of rich landowners. At the top were the nobility. Below them were a class of nearly rich landowners called the gentry. In the early 18th century there were another class of landowners called yeomen who were small landowners, described as farmers of the middle class. However, during the century this class became less and less numerous. However other middle class people such as merchants and professional men became richer and more numerous, especially in the towns. Below them were the great mass of the population, craftsmen and labourers. In the 18th century, probably half the population lived at subsistence or bare survival levels.
In the early 18th century England suffered from gin drinking. It was cheap and it was sold everywhere as you did not need a license to sell it. Many people ruined their health by drinking gin. Sadly, for many poor people drinking gin was their only comfort. The situation improved after 1751 when a tax was imposed on gin. At the end of the 17th century, it was estimated the population of England and Wales was about 5 1/2 million. The population of Scotland was about 1 million. The population of London was about 600,000. In the mid-18th century, the population of Britain was about 6 1/2 million. In the late 18th century it grew rapidly and by 1801 it was over 9 million. The population of London was almost 1 million. During the 18th century, towns in Britain grew larger. Nevertheless, most towns still had populations of less than 10,000. However, in the late 18th century new industrial towns in the Midland and the North of England mushroomed. Meanwhile, the population of London grew to nearly 1 million by the end of the century. Other towns were much smaller. The population of Liverpool was about 77,000 in 1800. Birmingham had about 73,000 people and Manchester had about 70,000. Bristol had a population of about 68,000. Sheffield was smaller with 31,000 people and Leeds had about 30,000 people.
