Explanation:

The view that decision making and politics are located in the framework of the government but non- government groups can exert their influence is called classical pluralism. The main question for classical pluralism is the distribution of power and influence in the political process.

Pluralism considers that as various groups of individual try to maximise their interests, conflicts are common and shifting of power becomes useful to bargain power between various interest groups.

Pluralists argue that inequalities would exist but it would be levelled by distribution of resources throughout a population. They support freedom of organisation and religion and electoral system with minimum two parties.

most people now work in jobs where they do one  kind  of work; they are carpenters, bankers, cooks, mechanics, and so forth. likewise, most  businesses produce  only certainkinds  of  goods  or  services, such as cars, tacos, or gardening  services. this feature of  production  is known as specialization.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
