Even though the scope of American literature continued to broaden in the second half of the twentieth

century, the consistency of ideas and themes could be found in.

America's writing Style

America's core values

America's literary heritage

America's leadership

America´s literary heritage

Explanation:

From the Colonial Period (17th century) and Early National Period to the Romantic Period (1830- 1870) to Realism and Naturalism (1870-1910) to the Modernist Period (1910-1945), they all contributed in some way or another to the Contemporary Period in literature, that reflected the social upheaval that acompanied the contemporary and all the other socio-political periods of America.

There is no such thing as a typical American writing style.

The core values (like the natural rights of people) do play a significant role but they don´t determine American literature.

America´s leadership or hegemony is a fact but it doesn´t make its literature consistent.
