Why do u think a tree was chosen to represent language families?

because of its branches

Because like a tree, languages have many branches such as dialects for different areas/regions that can differ a lot or a little. In addition, most languages tend to stem from the same roots such as latin, for example. Using a tree shows how they are all connected and how they relate to each other.

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.
