Answer:
The central idea of the article is to show that the experiments with human beings have already been done in very scary ways and without any type of regulation.
Explanation:
As we know, the experiences involving human beings, currently, are extremely regulated, so that the participants of the experience do not suffer any physical, chemical or biological problem. However, this has not always been a concern for scientists. As we can see in "Disturbing history of human experimentation", the experiences in human beings carried out in the past, presented very frightening and disturbing situations, many of them having children as participants. These experiments had no regulation whatsoever, allowing the scientist to manipulate the participant's body in any way he wanted, without worrying about his or her well-being.
