Which of the following was the most far-reaching development in the transportation revolution of the early 1800s?

canal building

the invention of the steamboat

the arrival of railroads

road construction

The correct answer is the arrival of railroads

Explanation: A railroad is a transportation system based on trains running on previously arranged tracks. Rail transport is prevalent in highly industrialized regions such as Europe, the far east of Asia and even in highly populated places like India.  And it helped the most in the time of revolution, because of the great distances.

Explanation:

The arrival of railroads was the most far-reaching development in the transportation revolution of the early 1800s.

The turnpike and the canal contributed to the emerging national economy, but the most significant development was the railroad. Railroads were faster and cheaper than canals to construct, and they did not freeze over in the winter. Since many states had overextended by borrowing heavily to finance their canals, much of the early railroad growth was developed by private investors.

In 1828, development of the first railroad began in Baltimore, and four years later the Baltimore and Ohio (B&O) Railroad reached 73 miles.  

Early railroad pioneers faced many challenges: Tracks with steep grades and sharp curves required more powerful locomotives, sparks from wood-burning engines caused fires, brakes didn't work well, and wooden rails topped with iron straps wore out quickly and broke loose, causing dangerous crashes.  

The intent of most early railroad builders had been monopolize the trade of certain districts, not to establish connections with competing centers, so few of the tracks were coordinated into railroad systems. Frequently, railroads went so far as to use tracks of different widths to prevent other lines from using their tracks.

Eventually, all of these railway obstacles were overcome. Modifications in locomotive design enabled trains to negotiate sharp curves, engines that could burn hard coal appeared, better brakes were developed, and the iron T-rail combined with crossties increased durability of the tracks. Rail gauges also gradually became standardized, linking the various rail lines together.

alliances in ww1 were different from ww2 because the entente in ww1 made up of serbia,russia,france,britan,japan and italy later america  and all allied in a sort of balance of power and too keep germany,austria-hungary,and the ottomans down. russia allied the serbians in order to exert its influence in the balkans while france allied the russians because france was still in dismay and insulted after the defeat to the germans during the unification of germany and britian allied the belgians after the germans invasion of belgium.in ww2 the alliances were in a preemptive attempt to deter any further wars into happening while germany and italy allied since they were insulted and humiliated after the previous war while also sharing a similar ideology of facsim along with japan which all 3 had a want for world domination and agreed to assist one another in the endevours
