Step-by-step explanation:
The factors that spurred industrial growth in the late 1800s were technological advancements, the expansion of railroads, and an increasing immigrant workforce.
Technological advancements such as the steam engine, telegraph, and telephone revolutionized communication, transportation, and production. These inventions allowed for faster and more efficient ways of conducting business, leading to increased industrial output.
The expansion of railroads played a major role in facilitating the transportation of goods and raw materials across the country. It connected different regions, making it easier for businesses to reach larger markets and access resources, thereby accelerating industrial growth.
Lastly, the influx of immigrants provided a steady and cheap labor supply. Many people came to the United States seeking employment opportunities, especially in urban areas where factories were concentrated. The availability of a large workforce enabled industries to expand and meet the growing demand for goods.
