The mechanization of the spinning process in the late 1700s led to the steam locomotive.          a high demand for cotton. the mechanical reaper. a decline in the economy

   A high demand for cotton

Explanation:  Until the mechanisation of the spinning process, the so-called spinning jenny, emerged, the spinning was done manually with cotton stocks, which were then sufficient. With the advent of mechanised spinning, i.e. with the spinning jenny 1764 innovation, yarn stocks were insufficient. With the development of an industrial, mechanised spinning process, the demand for cotton was growing enormously, so that by 1830 the entire production of yarn was purely mechanical rather than manual, and the potential for the production of raw cotton needed for industrial purposes became insufficient.
