How were race relations different in the 1960s than they are today?

Explanation: The 1960's was a decade of progress interracial marriage was allowed(probably not common but you could) and the Voting rights act removed the abuse of voter registration. However there were still large economic disparities. After years of segregation and discrimination many African Americans were in poverty. When no change was made by the government since most of the money was being spent on the war in Vietnam, there were mass protests throughout the country.    

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.

the correct answer is c. a piece or imprint of something that was once alive

hopefully that !
