Which of the following was one of the leading industrial nations of the early twentieth century?

a. ireland

b. germany

c. india

d. china

The correct answer is option B. Germany

Explanation:

The foundations of the economic strength at the beginning of the twentieth century were steel and coal, and Germany made great progress with both:

By 1914, Germany was the most powerful industrial nation in Europe. Under Bismarck's administration, Germany was closer than any other state of modern conceptions of social welfare. German workers enjoyed sickness, accident and maternity benefits, canteens and changing rooms and a national pension plan before they were thought of even in the most liberal countries.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
