Final answer:
New inventions altered American daily life by enabling the mass production and purchase of a wide variety of goods that were previously handcrafted or luxury items, making them widely available and affordable.
Step-by-step explanation:
One way that new inventions changed the daily lives of Americans is by making it possible for people to buy and sell goods rather than exclusively producing them at home or through local artisans. Industrialization and innovations in manufacturing led to a substantial increase in the availability and variety of goods. Items that were once luxuries or handcrafted became mass-produced and more affordable, which meant that the average American could now purchase items such as oil lamps, clocks, upholstered furniture, and significantly more varied clothing. This consumer revolution saw items like carpets, stoves, and domestic appliances entering more and more homes, enhancing comfort levels and showing the marks of a growing consumer society.
