Final answer:
The medical educational reform was spurred by the Flexnor report, which led to significant changes in medical education.
Step-by-step explanation:
The correct answer is A) Flexnor report.
The medical educational reform was spurred by the Flexnor report. The report, written by Abraham Flexnor in 1910, evaluated the quality of medical education in the United States and Canada. It revealed major deficiencies in the medical schools of that time, including inadequate faculty, lack of standardized curriculum, and poor facilities.
The Flexnor report led to significant changes in medical education, such as the closure of many subpar medical schools and the establishment of stricter admissions requirements and standardization of curriculum in medical schools.
