Explanation:
Man-made disasters can be prevented by applying the options above.
Alarm systems have proven to be very effective in alerting people to potential dangers in their environment whether in the home or workplace. For example, a fire alarm which goes off on the detection of smoke enable people to evacuate a building and the fire department to be called in to contain the situation.
Plans for evacuation and shelter in the event of a disaster cannot be underestimated. For example, the evacuation of people living near and around nuclear reactor sites or chemical plants should be planned for.
Regular inspection by licensed inspectors, of man-made structures goes a long way in helping determine whether those structures are still durable and reliable. For instance, regular inspection of old architectures like buildings and bridges enable us see warning signs about a potential disaster and take steps to stop it.
Implementation of a fail-safe mechanism recognises potential failures in system designs and protects against such failures resulting in a fatality.

The correct answer to this open question is the following.
The three power models in America are:
The Pluralist model.
This model of power establishes that there are certain kinds of groups that have similar interests and they associate to form groups of power that exert some control in society and politics and want to open more spaces to favor their particular interests.
So as there are many groups that have their own interests, but at the same time these interests are different from the other groups, then power is divided into different groups. They legally form political associations, unions, political groups that hire lobbyists and try to negotiate with legislators to make laws that favor their interests.
The Elite Theory.
This theory established that power in a nation relies on the hands of few groups of people that are wealthy enough that it can control most part of the decisions in politics and the economy.
This small group could be aristocrats, businessmen, or political families that have been exerting their control in the past in a quite discrete way. They do not like to appear in mass media or be acknowledged as the ones in power. They prefer to be the men behind the curtain, influence all the decisions.
Other theory such as the social theory or the Marxist Theory, establish that power should be in the hands of people and there has to be not only one source of power but different ones that help to balance power and decisions in a society. These theories favor the incursion of common citizens to the political spheres to make decisions that really took the people's needs into consideration.
