What event is commemorated by the Oklahoma Memorial in Oklahoma City?

The Oklahoma Memorial in Oklahoma City is dedicated to the victims of the Oklahoma City bombing, which occurred on April 19, 1995. This tragic event resulted in the loss of 168 lives and caused extensive damage to the Alfred P. Murrah Federal Building. The memorial serves as a place of remembrance for those who were killed, injured, and affected by the attack. It consists of various elements, including the Field of Empty Chairs, which symbolizes each victim, and other features that honor the memory of those lost and the resilience of the community.

The other choices, while important events in Oklahoma's history, do not pertain to the memorial. The Dust Bowl significantly affected many Oklahoma residents during the 1930s, but it is not the focus of the memorial. The Land Rush marked a critical moment in the state's settlement, and military veterans have their own commemorations but are not the specific subject of this memorial. Thus, the correct answer highlights the memorial’s specific intent to honor those impacted by the tragic bombing.
