Here is a question about this article: Immunization against the pathogens that cause diarrheal disease is a viable prevention strategy, however it does require targeting certain pathogens for vaccination. In the case of Rotavirus, which was responsible for around 6% of diarrheal episodes and 20% of diarrheal disease deaths in the children of developing countries, use of a Rotavirus vaccine in trials in 1985 yielded a slight (2-3%) decrease in total diarrheal disease incidence, while reducing overall mortality by 6-10%. Similarly, a Cholera vaccine showed a strong reduction in morbidity and mortality, though the overall impact of vaccination was minimal as Cholera is not one of the major causative pathogens of diarrheal disease. Since this time, more effective vaccines have been developed that have the potential to save many thousands of lives in developing nations, while reducing the overall cost of treatment, and the costs to society.
What is the answer to this question: What year was the Rotovirus vaccine used?
****
So... 1985

Here is a question about this article: Smaller boats and ships typically have machine-guns or fast cannons, which can often be deadly to low-flying aircraft if linked to a radar-directed fire-control system radar-controlled cannon for point defence. Some vessels like Aegis cruisers are as much a threat to aircraft as any land-based air defence system. In general, naval vessels should be treated with respect by aircraft, however the reverse is equally true. Carrier battle groups are especially well defended, as not only do they typically consist of many vessels with heavy air defence armament but they are also able to launch fighter jets for combat air patrol overhead to intercept incoming airborne threats.
What is the answer to this question: These weapons can be deadly to aircraft that is low if it is linked to what?

So... a radar-directed fire-control system radar-controlled cannon for point defence

Here is a question about this article: International influences help to encourage legal actions to be taken in India, such as the Geneva Declaration of the Right of Children Act was passed in 1924. This act was followed by The Universal Declaration of Human Rights in 1948 to which incorporated the basic human rights and needs of children for proper progression and growth in their younger years. These international acts encouraged major changes to the workforce in India which occurred in 1986 when the Child Labour (Prohibition and Regulation) Act was put into place. This act prohibited hiring children younger than the age of 14, and from working in hazardous conditions.
What is the answer to this question: What did the international acts do?

So...
encouraged major changes to the workforce
