Order the following impacts of the Industrial Revolution from the introduction of factories to the formation of labor unions: 1) Rise of factories, 2) Increased worker exploitation, 3) Formation of labor unions, 4) Enhancement of productivity.

The Industrial Revolution began with the rise of factories, which changed how goods were made. Factories allowed for increased productivity because machines could produce items much faster than people could by hand. However, this also led to increased worker exploitation, as factory owners often paid low wages and required long hours in poor conditions. In response to these challenges, workers began to form labor unions to fight for better pay and safer working conditions. Thus, the order of impacts starts with the rise of factories, followed by increased worker exploitation, then the enhancement of productivity, and finally, the formation of labor unions.
