It introduced provisions for local authorities to take action to improve living conditions, leading to the improvement of housing conditions in England. A: The Poor Law Amendment Act focused on providing relief to the poor, not specifically on housing conditions. B: The Housing and Town Planning Act came later in the 20th century and focused more on urban planning and development. D: The Health and Safety at Work Act primarily deals with workplace safety regulations, not housing conditions.

Correct Answer: A

Rationale: The correct answer is A: The release of the 2008 'Closing the Gap' report by WHO. This report highlighted the impact of social determinants on health outcomes, leading to increased awareness and focus on addressing these factors. The other choices are incorrect because B focuses on healthcare access, C on the establishment of WHO itself, and D on a report that emphasized individual lifestyle factors rather than social determinants.

Correct Answer: A

Rationale: The correct answer is A: The polio vaccine campaign. This initiative started in 1955 aimed to prevent the spread of polio by vaccinating the population. This campaign led by Dr. Jonas Salk and later by Dr. Albert Sabin successfully reduced polio cases. The other choices are incorrect because: B: The Healthy People initiative focuses on setting national health objectives, not specifically targeting polio. C: The Immunization Action Coalition promotes immunization practices but is not solely focused on polio. D: The National Vaccine Injury Compensation Program provides compensation for individuals who may have been injured by vaccines, but it does not aim to prevent the spread of polio.

Correct Answer: C

Rationale: The correct answer is C: The establishment of quarantine systems. Quarantine systems in the 19th century played a crucial role in reducing the spread of infectious diseases by isolating individuals with contagious illnesses. This practice helped prevent the further transmission of diseases within communities. Explanation: 1. Antibiotics (Choice A) were not introduced until the mid-20th century, so they were not a 19th-century development. 2. Vaccines (Choice B) were also not widely developed and utilized until later in the 19th and 20th centuries, so they did not significantly impact public health in the 19th century. 3. The invention of the microscope (Choice D) was a significant scientific advancement in the 19th century, but it primarily aided in the understanding of microorganisms rather than directly reducing the spread of infectious diseases. In summary, quarantine systems were the most effective 19th-century public health development in controlling the spread of infectious diseases compared to the other choices

Correct Answer: C

Rationale: The correct answer is C: The WHO Smallpox Eradication Program. This initiative was launched in 1977 by the World Health Organization (WHO) with the specific goal of eradicating smallpox globally. The program was successful, leading to the official declaration of smallpox eradication in 1980. The Global Immunization Campaign (Choice A) and the Polio Eradication Initiative (Choice B) are important global health efforts, but they do not specifically target smallpox eradication. The Global Health Security Agenda (Choice D) focuses on preventing, detecting, and responding to global health threats, but it is not directly related to the eradication of smallpox.
