What did the introduction of the power loom primarily improve?

The introduction of the power loom primarily improved textile production efficiency, revolutionizing how fabrics were woven. Before the advent of the power loom, fabrics were produced using traditional hand looms, which were labor-intensive and limited in speed and output. The power loom mechanized this process, allowing for much faster weaving of cloth and significantly increasing the quantity of textiles produced.

This innovation played a crucial role in the Industrial Revolution, as it helped meet the growing demand for textiles during a time when populations were urbanizing and consumer markets were expanding. The ability to produce textiles more rapidly and in greater volumes not only lowered costs but also boosted the entire textile industry, leading to economic growth and the emergence of factories as the centers of production.

The other options do not pertain to the primary function of the power loom. While military equipment, agricultural output, and transportation infrastructure were indeed important aspects of industrial advancement, they were not directly enhanced by the power loom. Instead, the power loom's impact was specifically centered on transforming the textile industry.
