What led to the growth of factories in England in the eighteenth century?

Base on the question that is asking to state the statement that led to the growth of factories in England in the Eighteenth Century, and base on my research and further investigation, I would say that the answer would be that the wealthy merchant class was more confident about investigating in new industries.

18th century is notable for Industrial Revolution in the world history. The period transitioned the use of the technology which factories started using machines and they became mechanized in other words. Richard Arkwright's patented spinning frame gave rise to the first true factory in England in 1769. With the advancement of the technology, factories started employing more people and achieving mass production.
