I have descriptions of things and need to match people. I'm not sure who this is.

Originally this news -gathering agency resembled a monopoly because of the power it possessed. At one time it was cpmposed of several agencies, principally in New York and the Midwest. A major reorganization in 1893 united these groups.

Based on the description provided, the agency in question is most likely the Associated Press (AP).

To verify your answer, you can follow these steps:

1. Identify the key details: The agency resembled a monopoly, was composed of several agencies in New York and the Midwest, and underwent a major reorganization in 1893.

2. Research the history of news-gathering agencies: Look into the background and evolution of news agencies during the late 19th century. Focus on major agencies that operated in both New York and the Midwest during that time period.

3. Compare the information: Compare the details from your description with the history of each agency you researched. Look for connections between the agency's structure, location, and any major reorganization that took place in 1893.

Given the clues provided, the Associated Press (AP) is the best match. The AP was initially formed as a cooperative organization in 1846 and had offices in New York and the Midwest. It went through a major reorganization in 1893, uniting various member agencies under one umbrella.

Remember, using additional resources such as history books, online archives, or official news agency websites can provide more specific and accurate information for your confirmation.
