Step-by-step explanation:
Effects of the Industrial Revolution
The correct answer to the question of what was not an effect of the Industrial Revolution is B. A decrease in trade. The Industrial Revolution had a profound impact on society, including major advances in transportation and communication technologies, as well as the significant growth of cities. Railways expanded rapidly, allowing for faster movement of people and goods, which increased trade and enabled the rise of urban centers. Communication also improved with inventions such as the telegraph and later the radio. Consequently, trade increased rather than decreased due to these developments.
For example, the introduction of the railroad transformed how goods were transported, increased the speed and ease of travel, and played a crucial role in expanding national and international trade. Also, the growth of industries and demand for raw materials led to increased international trade. The notion of decreased trade contradicts the other options which correctly highlight the positive changes in transport, communication, and urbanization.
