Answer:
Despite our many differences, Americans have always come together every Independence Day to celebrate our national birthday. Which is truly fitting. From the nation’s beginnings, our leaders have warned that strength can be found only in unity.
George Washington said that “the bosom of America” was open to all, but only if they were willing to be “assimilated to our customs, measures, and laws: in a word, soon become our people.” Alexander Hamilton said the nation’s future would depend on its citizens’ love of country, lack of foreign bias, “the energy of a common national sentiment, [and] a uniformity of principles and habits.”
Explanation:
Indeed, the one sure way to bring down America, according to Theodore Roosevelt, “would be to permit it to become a tangle of squabbling nationalities,” each insisting on its own identity. And Woodrow Wilson said flatly, “You cannot become thorough Americans if you think of yourselves in groups. America does not consist of groups. A man who thinks of himself as belonging to a particular national group has not yet become an American.”
Country level means country level, leveled by the country.
Part A: The statement that best states a central idea of this text is the second option: "When helping others, it is important to act; words alone are not enough."
The first option ("Good people volunteer...") is incorrect because the text makes no generalizations about good people at all; the third option ("In times of crisis...") is incorrect because the interaction between older and younger people in the text is not relevant; the fourth option ("Most people...") is incorrect because the person who needs help in the text is not a stranger, but a friend.
Part B: The essential detail from the text that helps to shape the central idea in Part A is the fact that, despite receiving over fifty messages in social networks offering support (words), Martin and his father were actually only visited by Jerome that day (actions).
