Question

The increased deployment of railroads in the 19th and 20th centuries had several effects. From the answers below, what was NOT an effect of the increased deployment of railroads?

a. Establishment of time zones
b. Increased use of coal
c. Increased deforestation
d. Development of the light bulb
e. Development of the telegraph

Answer 1

The development of the light bulb was not an effect of the increased deployment of railroads. While the establishment of time zones, increased use of coal, deforestation, and the development of the telegraph were all connected to the railroad expansion, the light bulb's development was driven by separate technological advancements in electricity use.

Step-by-step explanation:

The increased deployment of railroads in the 19th and 20th centuries had several effects, such as the establishment of time zones, increased use of coal due to steam engines, and increased deforestation from the demand for wood as a construction material and fuel. The development of the telegraph was closely connected with the expansion of the railroad system, as both were integral in supporting each other's operations and facilitating communication.

However, the development of the light bulb was not an effect of the increased deployment of railroads, which concentrates on electricity as a new source of energy, replacing steam. The invention of the light bulb was largely driven by Thomas Edison's work and increased the use of electricity in homes and workplaces, but it's development wasn't a direct consequence of the growth of railroads.

Answer 2

d. Development of the light bulb

Step-by-step explanation:

• The increase of the deployment of the railroads in the 19 and the 20th century had several effects on the nations and included all the development of the time zones and increased use of the coal and increased used of the deforestation of the forests but the development of the light bulb was developed earlier.
