Final answer:
The 20th Amendment, also known as the Lame Duck Amendment, decreased the time between the presidential election and inauguration. Advancements in communication (telegraph and telephone) and transportation (railways and automobiles) allowed for quicker transfer of power.
Step-by-step explanation:
The 20th Amendment, also known as the Lame Duck Amendment, reduced the amount of time between the presidential election and the inauguration of the new president. This amendment was made possible due to advancements in transportation and communication during the early 20th century.
Firstly, the widespread adoption of the telegraph and telephone allowed for faster and more efficient communication across long distances. This meant that election results could be transmitted quickly, allowing for a quicker transfer of power.
Additionally, transportation improvements, such as the expansion of railways and the growing use of automobiles, facilitated faster travel between cities and states. This made it easier for the incoming president to reach the capital and assume office without delay.
