Answer:
Option A.
Explanation:
A scientist who helped survey the new national capital, is the right answer.
Benjamin Banneker can be best described as a free African-American journal author, astronomer, naturalist, farmer and surveyor from America. Banneker has been regarded as the leading African-American man of science. At the request of President Thomas Jefferson, he joined a group under the leadership of Major Andrew Ellicott that inspected the primary boundaries of the District of Columbia, the national capital region of the U.S. He was the only person who in two days presented a complete layout of the major buildings, parks and streets.
The 1860 election of Abraham Lincoln was a turning point for the United States. Throughout the tumultuous 1850s, the Fire-Eaters of the southern states had been threatening to leave the Union. With Lincoln’s election, they prepared to make good on their threats. Indeed, the Republican president-elect appeared to be their worst nightmare. The Republican Party committed itself to keeping slavery out of the territories as the country expanded westward, a position that shocked southern sensibilities. Meanwhile, southern leaders suspected that Republican abolitionists would employ the violent tactics of John Brown to deprive southerners of their slave property. The threat posed by the Republican victory in the election of 1860 spurred eleven southern states to leave the Union to form the Confederate States of America, a new republic dedicated to maintaining and expanding slavery. The Union, led by President Lincoln, was unwilling to accept the departure of these states and committed itself to restoring the country. Beginning in 1861 and continuing until 1865, the United States engaged in a brutal Civil War that claimed the lives of over 600,000 soldiers. By 1863, the conflict had become not only a war to save the Union, but also a war to end slavery in the United States. Only after four years of fighting did the North prevail. The Union was preserved, and the institution of slavery had been destroyed in the nation.
