Which change can most directly reduce death rate?

Answer and explanation

Correct answer: Improvement in vaccination and medical facilities

Answer: C, improvement in vaccination and medical facilities. Death rate measures deaths in relation to the population during a specified period. Vaccination helps prevent certain infectious diseases, while medical facilities support diagnosis, treatment, emergency care, and management of illness. Therefore, better public health can directly reduce avoidable deaths and lower mortality. A may change the number of people in a place but does not directly improve survival there. B changes the physical area, not health conditions or the death rate itself. D is only a measurement or calculation; counting density cannot reduce deaths. C is the only option that directly addresses disease prevention and treatment. Memory cue: to reduce mortality, think prevention plus treatment—not area or population counting.
