What is the primary constitutional task of the vice president, besides succeeding the president in case of death, resignation, or incapacitation?
a. to act as chief admiral of the u. s. navy
b. to serve as speaker of the house of representatives
c. to cast tie-breaking votes in the senate
d. to represent the president overseas

C. to cast tie-breaking votes in the Senate

Explanation:

In the 20th and 21th centuries the vicepresident's figure turned into a position more related to the executive branch, and is often considered a crucial constituent in the president's administration.

Apart from succeeding the president in those two cases, the only remaning constitutional duty of a vicepresident is to chair the Senate. A vice president is not able to vote in the Senate but for breaking a tie, and needs the permission of the senators to appeal to the Senate in a formal way.

answer: secession

secession, as it applies to the outbreak of the american civil war, comprises the series of events that began on december 20, 1860, and extended through june 8 of the next year when eleven states in the lower and upper south severed their ties with the union. the first seven seceding states of the lower south set up a provisional government at montgomery, alabama. after hostilities began at fort sumter in charleston harbor on april 12, 1861, the border states of virginia, arkansas, tennessee, and north carolina joined the new government, which then moved its capital to richmond, virginia. the union was thus divided approximately on geographic lines. twenty-one northern and border states retained the style and title of the united states, while the eleven slave states adopted the nomenclature of the confederate states of america.

explanation:

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
