Which of teh following would explain the importance of the trans-siberian railroad to russia's economy? (schoology test)

1.  Trans-Siberian Railway Russian railway from Moscow to Vladivostok. The world's longest railway, the major part, e from Chelyabinsk, was built between 1891 and 1905, giving Russia access to the Pacific via a link with the Chinese Eastern Railway in Manchuria.

2.  The Trans-Siberian Railroad thus had two completion dates: in 1904 all the sections from Moscow to Vladivostok were linked and completed running through Manchuria; in 1916 there was finally a Trans-Siberian Railroad wholly within Russian territory.

3. TRANS-SIBERIAN RAILWAY

The construction of the Trans-Siberian Railway between 1891 and 1916 ended the era of great transcontinental railway building. The Trans-Siberian stretches 5,776 miles between Moscow's Yaroslavsky Station and Vladivostok (6,117 miles from St. Petersburg). It takes a minimum of a week to traverse that distance by train.

The longest railway in the world, the Trans-Siberian project was mired in controversy from the moment Tsarevich Nicholas shoveled an inaugural spade full of dirt into an awaiting wheelbarrow in Vladivostok on May 31, 1891, until the completion of the Amur River Bridge at Khabarovsk in 1916. A technological marvel at the time, it soon bore the reputation of "a monument to bungling." The rails and crossties were too light, causing frequent derailments; the wooden bridges were flimsy; and, since the builders were mostly exiles and convicts, there was justifiable reason to believe that much of the line had been sabotaged.

a and b because with the other three, they simplify to something else.
