What equipment does Gracie agree to fetch after Benjamin's instructions?

The correct choice reflects the essential equipment needed in emergency situations where a person may require immediate medical assistance. In this context, an AED (Automated External Defibrillator) is crucial for delivering electric shocks to restore normal heart rhythms in cases of cardiac arrest. It's a vital tool that can improve survival rates significantly when administered promptly.

Additionally, a first aid kit is necessary to provide immediate care for injuries, which allows responders to address a wide range of medical situations, from minor wounds to more serious injuries. Having these two items on hand can make a significant difference in an emergency response.

In contrast, while options like a fire extinguisher and blanket might be useful in particular scenarios, they do not address the immediate medical needs associated with injuries or cardiac events as effectively as an AED and a first aid kit do. Items like splints and gloves could be beneficial for certain injuries but are more specific and do not cover the broader need for cardiac response equipment. Thus, the combination of an AED and a first aid kit is the most comprehensive choice for emergencies.
