Rivers were too shallow for ships to travel year-round, making it necessary to travel by stagecoach, which was very slow.

Please select the best answer from the choices

c.  Severe traffic congestion on the few roads that were available made it difficult to get from one city to the other.

Explanation:

Before the construction of the railroad, transportation in Texas, and most states, was very difficult and slow. People were transported in caravans to guard against the dangers they might encounter on the road, for example, from being assaulted or attacked by wild animals. The terrain was also a challenge and it took days or even months to travel between cities.

After the creation of the railway, traveling became cheaper and faster. In Texas, the railroad was developed since 1875 to facilitate the transportation of livestock between various cities and Mexico.
