the awnsers are  design and factory made

Explanation:

The industrial revolution spurred new inventions, cheaper prices, and new ways of thinking like economic and ergonomic efficiency. Gas became the preferred source of heat and allowed ovens to become smaller and lighter. The turn of the 20th century saw a greater interest in saving time in factory production, and this interest eventually flowed into kitchen design as well. The kitchen of the late 1800’s featured very little storage, as cabinets weren’t in production for the home. In 1899 the Hoosier Manufacturing Company was formed and they introduced a freestanding kitchen storage piece, known as the Hoosier Cabinet. It incorporated space saving features like upper and lower cabinetry, in-cabinet storage spaces for things like flour and sugar, and often featured a pullout work surface. Although the Hoosier cabinet wasn’t large, it filled the storage void for the homemaker and made working in the kitchen that much more efficient.
