Explanation:

Question 1

The expansion of railroads in the industrial era (late 19th - early 20th century) was closely tied to the growth of industries like steel (for railroad construction) and oil (for fuel, lubrication). The railroad expansion facilitated the transportation of raw materials and finished goods, which spurred the development of steel and oil industries. So the blank is likely "steel".

Monopolies and trusts (large corporate combinations) in the Gilded Age (late 19th century) led to issues like lack of competition, which allowed companies to set high prices, exploit workers (low wages, poor conditions), and limit consumer choice. A major issue was the concentration of economic power in the hands of a few, leading to unfair business practices, wealth inequality, and political corruption as monopolists influenced government.

• Phonograph (invented by Edison): It revolutionized entertainment and communication. It allowed people to record and play back sound, which led to the development of the music industry. People could now listen to music at home, and it also had uses in business (e.g., dictation).
• Electric light (Edison's incandescent bulb): It transformed daily life by extending the usable hours of the day. Factories could operate at night, increasing productivity. Homes were no longer reliant on dangerous and dim oil lamps or gaslights, improving safety and quality of life. Streets with electric lighting became safer, enabling nighttime activities and urban development.

Answer:

steel
