Which form of terrorism requires simple equipment and minimal training?

The correct answer is arson because it typically requires only basic materials and straightforward techniques to execute. In arson, the act of deliberately setting fire can often be performed with readily available items such as matches, flammable liquids, and other combustible materials that are not complex to procure or utilize. This accessibility makes it feasible for individuals with minimal training or expertise to carry out the act.

While other forms of terrorism, such as bombing, kidnapping, and sabotage, often involve more sophisticated methods, specialized knowledge, or advanced planning, arson's simplicity is its defining characteristic. Bombing, for instance, usually involves explosives and triggering mechanisms that necessitate a higher level of technical skill and knowledge. Kidnapping requires understanding security measures, which can involve extensive planning and potentially coordination with others. Sabotage often entails tampering with infrastructure or systems, which may also need more intricate methods and can pose substantial risks if not done correctly.

Thus, arson stands out as the form of terrorism that can be executed with minimal training and simple tools.
