[{'content': 'A young couple hiking in a wilderness area discovered the body of a man apparently in his 20s. He appeared to have been dead a few days, but animal predation was minimal. A postmortem examination was performed by the county medical examiner, and no evidence of penetrating wounds (bullet, lacerations, etc.) was found. A plain radiograph showed a fractured hyoid bone, but the calvaria and other bones appeared to be intact. Which of the following is the most likely cause of death? \nSelect and explain. \nA. Myocardial infarction (heart attack), B. A fall from a height that resulted in fatal in ternal bleeding, C. Subdural hematoma, D. Strangulation', 'role': 'user'}, {'content': 'Answer: D \nExplanation: A fractured hyoid bone is evidence of strangulation. A fall from a height and subdural hematoma would likely be accompanied by fractured bones. Whereas myocardial infarction or poison remain possibilities, the medical examiner would have a high index of suspicion for strangulation because of the fractured hyoid bone.', 'role': 'assistant'}]
