Explanation:

3.

In the early 1900s, the United States entered a period of peace, prosperity, and progress. In the nation's growing cities, factory output grew, small businesses flourished, and incomes rose. As the promise of jobs and higher wages attracted more and more people into the cities, the U.S. began to shift to a nation of city dwellers. By 1900, 30 million people, or 30 percent of the total population, lived in cities.

4.

The Progressive Era was mostly fueled by urban, educated people who saw that the country would benefit if everyone had opportunities to be their best. One of the major goals of the movement became making a better way of life for immigrants, minorities, and poor residents of cities

2. Yellow journalism and the yellow press are American terms for journalism and associated newspapers that present little or no legitimate, well-researched news while instead using eye-catching headlines for increased sales. Techniques may include exaggerations of news events, scandal-mongering, or sensationalism. By extension, the term yellow journalism is used today as a pejorative to decry any journalism that treats news in an unprofessional or unethical fashion.

Literary realism is a literary movement that represents reality by portraying mundane, everyday experiences as they are in real life. ... Literary realism seeks to tell a story as truthfully as possible instead of dramatizing or romanticizing it.
