The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Equality of opportunity is a central value in the American political system. I am going to choose the United States Congress
I consider that US Congress is most responsible for advancing the principle of equality of opportunity in the United States because Congress has the power to create laws and legislation that aims to strengthen the principle of equality.
Let's have in mind that the American founding fathers created the nation based on liberty and equality, and those concepts were an important part of the Declaration of Independence promulgated on July 4, 1776, and of the Constitution created during the Constitutional Convention of Philadelphia in 1787.
American legislators should be committed to creating the kinds of laws that support the principle of equality, instead of spending too much time with lobbyists, negotiating legislation that benefits particular interests or political groups' interests.
US citizens voted for congressmen to represent them and fight for their concerns and demands.
Explanation:
I am working at a graphic firm and a project needs to completed that me and my team members are working on. As a need of the project I have to stay late at my office to after work to met the deadlines. So it is my responsibility to work late and deliver the project in time.
But I have also promised my neighbor to take him to an important appointment that day at 6:30 p.m., which is also important to me as I have promised him and the appointment is important.
In this situation, I will see and try to find a friend of mine who knows my neighbor so that he can take my neighbor to the appointment as scheduled whereas I can stay late at office and complete my project long with the other team members.
