Which of the following is responsible for the dramatic increase in life expectancy during the twentieth century?

  • A. Technology increases in the field of medical laboratory research
  • B. Advances in surgical techniques and procedures
  • C. Sanitation and other public health activities
  • D. Use of antibiotics to fight infections
Correct Answer: C

Rationale: The correct answer is C: Sanitation and other public health activities. Sanitation improvements, such as clean water supply and waste disposal, have played a significant role in reducing infectious diseases and improving overall health, leading to the dramatic increase in life expectancy during the twentieth century. This is supported by historical data showing a correlation between improved sanitation and decreased mortality rates. Other choices are incorrect because while technology, surgical advances, and antibiotics have contributed to medical progress, they alone cannot account for the significant increase in life expectancy seen during the twentieth century.
