The correct answer is D. The lasting machine sped up the process and saved workers time and energy.

Explanation:

The lasting machine was invented by the end of the 19th century by Earnst Matzeliger, this machine included molds that resemble customer feet as well as mechanisms that made it possible to attach the leather of material of the shoe to the mold and the sole. This means part of the process of creating shoes was then made by machines rather than by shoemakers. Due to this, the lasting machine led to the expansion of shoe production as it was faster and easier to create a pair of shoes, especially because the work done by the machine was highly time and energy consuming and often required experts. According to this, the lasting machine changed the way shows were made because it "sped up the process and saved workers time and energy".
