The Chicago West EMS System covers areas north of which street to Fullerton?

• A. 43rd Street
• B. 130th Street
• C. 99th Street
• D. 119th Street

Answer: (D)

Understanding how EMS system boundaries are described helps you read these questions easily. When the description says the area is “north of a street to Fullerton,” the street named first is the southern edge and Fullerton is the northern limit. So the covered area includes everything north of that southern street up to Fullerton Avenue.

For the Chicago West EMS System, the southern boundary is 119th Street and the northern boundary is Fullerton Avenue. Therefore, the area covered is all locations north of 119th Street up to Fullerton. That makes 119th Street the correct boundary.

The other streets don’t match the official boundary. For example, 43rd Street sits far north and would imply a boundary extending differently, while 99th and 130th lie south of 119th, which would not describe the actual west system’s coverage.
