Final answer:
The British textile industry advanced due to the availability of raw materials, technological innovations, and government protection.
Step-by-step explanation:
The advancement of the British textile industry was led by several factors. Firstly, the availability of raw materials from the American south, thanks to slave labor, provided a steady supply for production. Secondly, the development of new machines such as Kay's flying shuttle, Hargreaves' spinning jenny, and Arkwright's water frame significantly increased productivity and reduced labor hours required for production. Lastly, the British government's protection of textile technology and prohibition of textile machinery export ensured that British cloth remained dominant in Europe.
