Answer: The last option.
Explanation: The precautionary principle would be considered to be most strictly applied where the precautionary measure is most disproportionate to the given risk. In all but the last option, there are either measures taken in response to concrete problems, or the precautionary measures are actually relaxed. In the last option, though, there are merely “fears” that antibiotics and growth hormones could cause harm (no experimental evidence), but the school board still takes the strict precautionary measure of mandating that schools only serve organic milk.
Informal means of control – Internalizationof norms and values by a process known as socialization, which is "the process by which an individual, born with behavioral potentialities of enormously wide range, is led to develop actual behavior which is confined to the narrower range of what is acceptable for him by the group standards."[2]
Formal means of social control – External sanctions enforced by government to prevent the establishment of chaos or anomie in society. Some theorists, such as Émile Durkheim, refer to this form of control as regulation.
As briefly defined above, the means to enforce social control can be either informal or formal.[3] Sociologist Edward A. Ross argues that belief systems exert a greater control on human behavior than laws imposed by government, no matter what form the beliefs take.
Social control is considered one of the foundations of order within society.
