The correct answer to this open question is the following.

The innovations that helped Americans to conquer the western frontier were the following. They had, for example, modern railroads that served to transport people and goods. The telegraph improved communications at the time. Better weapons helped settlers to defend their property and barbed wire helped to divide the property and keep the cattle safe from robbery.

What attracted folks to move to the far west of the Great Plains was the ambition to get more land. People thought that this land could be used to farm all kinds of crops. The Homestead Act of 1862 really facilitated farmers to get land to be farmed. The presence of railroads allured farmers to move to the plains, thinking that their products could be easily transported to different parts of the country and increase trade opportunities.
