The correct answer is option Social Studies.
A secondary explosive device refers to bombs placed at the scene of an ongoing emergency response with the intention of causing casualties among the responders. This topic falls under the subject of Social Studies as it involves studying acts of violence, terrorism, and their impact on society.
One example of a secondary explosive device is the attack on the Boston Marathon in 2013, where bombs were detonated near the finish line, resulting in fatalities and injuries.
The correct answer is option Social Studies. Secondary explosive devices are intended to cause harm to emergency responders. The concept of secondary explosive devices is not unfamiliar in history, with past incidents like the Boston Marathon bombing illustrating their devastating impact.
Law enforcement and military personnel often use devices such as metal detectors to search for these hidden threats. For instance, the Boston Marathon attack involved homemade bombs, resulting in casualties and initiating a manhunt.
Explosions, whether natural or engineered, have various causes but share the common trait of a rapid release of energy. Historical examples of innovations in explosive technology include gunpowder, nitrocellulose, and dynamite.
When used with malicious intent, as with secondary explosive devices, the consequences can be catastrophic, highlighting the need for vigilant public safety measures.
