Which two sentences from the passage best support the inference that Douglass had great determination? In 1861, the nation erupted into civil war over the issue of slavery. Frederick Douglass worked tirelessly to make sure that emancipation would be one of the war's outcomes. He recruited African-American men to fight in the U. S. Army, including two of his own sons. His sons served in the famous 54th Massachusetts Volunteer Infantry. When black troops protested they were not receiving pay and treatment equal to that of white troops, Douglass went into action. He met with President Abraham Lincoln to lobby on their behalf.
As the Civil War progressed, emancipation seemed forthcoming, and Douglass intensified the fight for equal citizenship. He argued that freedom would be empty if former slaves were not guaranteed the rights and protections of American citizens. A series of postwar amendments sought to make some of these tremendous changes. The 13th Amendment abolished slavery. The 14th Amendment granted national birthright citizenship. The 15th Amendment stated that no one could be denied voting rights on the basis of race, skin color, or previous servitude.
