Step-by-step explanation:
During the Industrial Revolution, several positive developments occurred. Three of these developments were the advancements in textile machinery, the widespread use of gas lamps, and the growth of the middle class.
- Advancements in textile machinery: The Industrial Revolution saw the invention of machines like the spinning jenny and the power loom, which greatly increased the speed and efficiency of textile production. This led to a massive increase in industrial output and made consumer goods more affordable.
- Widespread use of gas lamps: Before the Industrial Revolution, lighting was limited to candles and oil lamps. The development of gas lamps meant that people could now be active at all hours of the day and night. This not only improved safety but also contributed to the growth of urban centers.
- Growth of the middle class: The Industrial Revolution shifted society, creating a new social class known as the middle class. This class consisted of factory owners, entrepreneurs, and skilled workers. The middle class saw significant economic and social mobility, improving living standards and increasing social opportunities.
