Question

1. which invention allowed faster and cheaper transportation?

Explanation:

The invention of the steam engine (and later developments like the railroad, steamships) or the internal combustion engine (for automobiles, trucks) allowed faster and cheaper transportation. For example, the railroad system using steam - powered locomotives could transport large quantities of goods and people over long distances at a lower cost per unit and higher speed compared to earlier methods like horse - drawn carriages or sailing ships. Another key invention is the automobile with the internal combustion engine, which revolutionized personal and small - scale transportation, making it faster and more affordable for many over time as production methods (like assembly lines) reduced costs.

Answer:

Inventions like the steam engine (enabling railroads and steamships) or the internal combustion engine (enabling automobiles, trucks) allowed faster and cheaper transportation. A prominent example is the railroad system with steam - powered locomotives, which revolutionized long - distance transport by reducing cost per unit and increasing speed compared to prior methods.
