Final answer:
The early results of the Industrial Revolution included an increase in the population of cities, longer average workdays, and a larger middle class. Hence, the correct answer to the question is 'D) All of the above'. These changes were driven by technological advancements allowing factories to be city-based and the resultant urban migration.
Step-by-step explanation:
As an early result of the Industrial Revolution, several aspects of society changed significantly. These changes include A) the population of cities, B) the length of the average workday, and C) the size of the middle class. Therefore, the correct answer is D) All of the above.
The Industrial Revolution sparked a shift from rural to urban life, as people sought jobs in burgeoning industrial centers. The development of technology, such as the steam engine, allowed factories to relocate to cities, prompting mass urban migration.
The growth of such industries inevitably led to cities expanding in population and the urbanization process played a key role in shaping the social landscape.
Concurrently, the need for a constant workforce resulted in longer workdays for many, while at the same time, improved education and economic opportunities contributed to the enlargement of the middle class. The Industrial Revolution thus remodeled the fabric of society, influencing everyday life for generations to come.
