Describe two reasons monopolies and trusts were considered to be problems during the Progressive Era. Thank you!

The Progressive Era was a period of widespread social activism and political reform across the United States that spanned the 1890s to the 1920s. The main objectives of the Progressive movement were addressing problems caused by industrialization, urbanization, immigration, and political corruption.

Please correct me if i'm wrong :)

i think the answer is c, rivers.

explanation:

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.

letter d is correct.
