Question

mod-fall final part i
the introduction of the light bulb to the factory led to —
○ the use of steam-powered machinery in factories nationwide
○ increased accidents and deaths among factory workers
○ factories staying open longer

Explanation:

To solve this, we analyze each option:

• Steam - powered machinery was used before light bulbs (related to the Industrial Revolution's earlier phase), so the first option is incorrect.
• Light bulbs improved visibility, which should decrease accidents, not increase them, so the second option is wrong.
• Light bulbs provide artificial light, allowing factories to operate beyond daylight hours, so factories could stay open longer.

Answer:

C. factories staying open longer (assuming the options are labeled A, B, C with A being "the use of steam - powered machinery in factories nationwide", B being "increased accidents and deaths among factory workers", and C being "factories staying open longer")
