I need done very quick

The government is concerned about pollution being generated by the steel industry. Assume that there are 3 steel firms producing a total of 3,000 tons of pollution before any government regulation. (Each firm produces 1,000 tons of pollution.) The government wants to reduce pollution by a total of 900 tons (i.e. they want total pollution generated by the industry to be 2,100 tons). The table below summarizes each firm's cost of reducing pollution. Firm 1 Firm 2 Firm 3 Amount of pollution produced before government intervention 1,000 tons 1,000 tons 1,000 tons Cost of reducing pollution (per ton) $50 $20 $30 From an economic efficiency standpoint, should all firms be required to reduce pollution by 300 tons each in order to achieve the government's goal? Why or why not? O No, because each firm starts off with a different initial amount of pollution produced before government intervention. O Yes, because each firm starts off with the same initial amount of pollution produced before government intervention. O Yes, because each firm has the same cost of reducing pollution. O No, because each firm has a different cost of reducing pollution.In which of the four stages of the normal political development is an NGO's ability to influence the issue the greatest? O Implementation Stage O Legislative Stage Development stage O Politicization stage
