The line from the text that best supports the central idea of Immigrants being treated poorly on their journey to a new life is c.Scowling and gesturing, they pushed and pulled the passengers, herding us into separate groups as though we were animals.
Explanation:
The central idea found in The Immigrant Kids was that immigrants were often treated poorly on their journey to a new life and this was buttressed by the line from the text which said that the immigrants were pushed and pulled and also herded into separate groups as if they were animals.
Being pushed and pulled by scowling men and herding immigrants like animals is an example of the poor treatment they faced most times on their journey to a new life.
