Final answer:
Kristal is most likely to provide help to the motionless person on the beach in scenario C, where she is alone and currently in med school, due to a reduction in the bystander effect and her medical training.
Step-by-step explanation:
The likelihood of Kristal providing help to the motionless person is influenced by the presence of others and her knowledge in handling such situations. According to the concept of the bystander effect, individuals are less likely to offer help to a person in need when there are other people present, assuming someone else will take action. Applying this to Kristal's scenarios:
- Scenario A: Kristal is in grad school and on a crowded beach. Her general training may not be specific to medical emergencies, and the crowded setting may reduce the likelihood of her intervening due to the bystander effect.
- Scenario B: Kristal is in med school and on a crowded beach. Her medical training increases the likelihood she will recognize the seriousness of the situation, but the bystander effect may still deter her action.
- Scenario C: Kristal is in med school and alone on the beach. Being the only one present and with medical training, she is most likely to intervene.
- Scenario D: Kristal is in grad school and alone on the beach. She may feel more responsibility than in a crowded setting, but her lack of medical training may affect her confidence in assisting.
Therefore, Kristal is most likely to provide help in scenario C, where she is jogging alone and has medical training, which reduces the influence of the bystander effect and equips her with the skills to potentially provide appropriate assistance.
