Answer:
The Tuskegee Syphilis Experiment
Explanation:
The Tuskegee Syphilis Experiment was a social research that sought to find out the natural history of syphilis, with the purpose of justifying treatment programs for blacks. 
Termed as “Tuskegee Study of Untreated Syphilis in the Negro Male.” It started in 1932, and lasted till 1972, when it was discovered that the reasearch was conducted without the benefit of patients’ informed consent.
Following a governmental review of the study, it was concluded that, the subjects involved in the research had been misled and had not been given all the facts required to provide informed consent, hence, the study was considered to be "ETHICALLY UNJUSTIFIED" that is, the knowledge acquired was minute when compared with the risks the study posed for its subjects.
Therefore, The Tuskegee Syphilis Experiment was an example of a major ethical mistake in the history of social research.
 
        
             
        
        
        
I think government systems have their weakness and strengths. Having a just society needs good governance that promotes the welfare of people that also has a strong implementation of the rule of law. Enforcement of the law to create a peaceful community is important. 
        
                    
             
        
        
        
The correct answer to this open question is the following.
Although the question does not include options, we can say the following.
This is a photograph of !Kung hunter-gatherers, a group of modern foragers. The study of the !Kung and other modern foragers as well as the geometry of ancient bones provide insight into whether people had to work harder to acquire their food as hunter-gatherers or as agriculturalists. The statements that correctly reflect related research findings are the following:
"There is a great deal of variation in how much both hunter-gatherers and agriculturalists work." And "bone signatures in Coastal Georgia indicate a lessened work load with the onset of agriculture."  
For the !Kung, the work load heavily depended on the conditions of the environment. They had to consider their living conditions and necessities to know what to do and the way to work to fulfill their necessities. Researcher Christopher Ruff shared important knowledge about how bones found in the Coastal area show that these people had less stress due to the fact that their level of work and general activities were lower. The weather conditions of the region allowed them to grow crops and harvest successfully in the coastal region. Raw materials and natural resources were plenty in this area.

Answer:
we also need this claim to be replicated by others
Explanation:
A claim must be falsifiable in order to be useful. However, we also need this claim to <u>be replicated by others</u>.
A falsifiable claim is a claim that possesses some probability, attributes or observations that can make it regarded as false. For a claim to be regarded as false, there should be a repeated pattern by others.
