All of the following were concerns that shaped politics during the gilded age except?
a. settled mostly in eastern cities.
b. preserved their heritage after they came to the united states.
c. established unions to pressure employers for higher wages.
d. encountered very little discrimination in employment.

The options for this question aren't correct and are probably of another question.

Thus let's see the general features of the Gilded Age:

The Gilded Age is the period between the end of the Civil War and the beginning of the 20th century. Its name was given by a book by Mark Twain called The Gilded Age: A tale of today.

This period is characterized by the growth of monopolies in the economy that led to many corruption scandals where politicians plotted with industrialists and businessmen. An expression famous at the time was  robber barons.

It was also an age of great industrialization of the country that led to many changes in the social structure of the society. More fabrics meant a growth in the working class that was violently explored by the bourgeoisie. That's why in this period there was also an increase in labor movements. Violent exploration of the working class led to a moment of economic growth and production of wealth that wasn't equally distributed.

In this period the US received thousands of immigrants that created a large population of poor people in the cities living in tenements. This was famously shown in the book How the other half lives by Jacob Riis, himself a Danish migrant.

It was also a time of railroad expansion with the construction of the Transcontinental Railroad and the muckracking journalism where reporters would focus their work on exposing corruption between politicans and the economic elite.
