Question

1. how did the division of labor make factories more productive?

if each worker did just one step over and over, he or she could get really good and really fast at it.
division of labor allowed workers to perform every task required to make a product, so they could switch tasks easily.
dividing the tasks among many workers kept them from getting tired, which meant they could work longer hours.
if several workers were used to create one product, production could continue even if one person got sick.

Explanation:

Division of labor focuses on splitting production into specialized, repetitive tasks. Workers mastering one specific task gain proficiency and speed, directly boosting factory productivity. The other options misdescribe the core mechanism: division of labor does not involve workers doing all tasks, does not prevent tiredness inherently, and continuity during absence is a secondary benefit, not the primary productivity driver.

Answer:

A. If each worker did just one step over and over, he or she could get really good and really fast at it.
