Educational worksheet on homesteading, highlighting push and pull factors that led people to move westward.

Let me work through this problem step by step.

The task is asking to sort factors into "Push Factors" and "Pull Factors" for why homesteaders left their homes in the East and moved onto the plains.

First, let me understand what push and pull factors are:
- Push factors = negative things that force people to leave (problems they're running away FROM)
- Pull factors = positive things that attract people to go somewhere (benefits they're moving TOWARD)

Now let me analyze each factor:

1. "Overcrowding in the East" - This is a problem/negative situation that would make people want to leave. This is a PUSH factor.

2. "To escape from poverty" - People are running AWAY from poverty. Poverty is the negative thing pushing them out. This is a PUSH factor.

3. "Letters from those who had already gone West" - These letters would tell people about good opportunities and encourage them to come. This attracts/motivates people to move. This is a PULL factor.

4. "To escape religious or racial persecution" - People are fleeing/running away from persecution. Persecution is the negative thing pushing them out. This is a PUSH factor.

5. "Newspaper or magazine articles about life on the Great Plains" - These articles would describe the benefits and opportunities, attracting people to move there. This is a PULL factor.

6. "Advertisements by railroad companies" - Railroad companies were advertising to get people to move West, promoting the benefits. This attracts people. This is a PULL factor.

Let me verify my answers:
- Push (negative, leaving something bad): Overcrowding, escaping poverty, escaping persecution ✓
- Pull (positive, attracted to something good): Letters describing opportunities, newspaper/magazine articles, advertisements ✓

Final Answer:

Push Factors:
- Overcrowding in the East
- To escape from poverty
- To escape religious or racial persecution

Pull Factors:
- Letters from those who had already gone West
- Newspaper or magazine articles about life on the Great Plains
- Advertisements by railroad companies
