Step-by-step explanation:
The 'jewel of the crown' referred to the colony of India, which was considered the most valuable possession of the British Empire. India was prized for its abundant resources, including spices, tea, and cotton, which were highly sought after in European markets. Additionally, India provided a vast source of cheap labor for British industries.
The impact of railroads on America was significant. Railroads played a crucial role in the country's westward expansion and industrialization during the 19th century. They facilitated the transportation of goods, allowed for efficient movement of people, and opened up new markets. Railroads also contributed to the growth of towns and cities along their routes and stimulated economic development.
