Question

look at the graphic. a muckraker conducted an investigation and wrote an article. people read the article and were shocked by the facts. which phrase best fits in the last box? the public began to take action by setting up committees and supporting reform candidates the public turned against the muckrakers and tried to shut down their newspapers the public was outraged and demanded that the government regulate journalistic practices the public largely ignored the muckrakers’ articles

Explanation:

Muckrakers were journalists who exposed social and political problems. After people were shocked by the facts in their articles, the public typically took action for reform, like forming committees and supporting reform candidates. The other options don't fit: the public didn't turn against muckrakers (they were seen as exposing issues), didn't demand regulating journalism (muckraking was about exposing, not journalistic practices), and didn't ignore the articles (they were shocked, so engaged).

Answer:

The public began to take action by setting up committees and supporting reform candidates
