Why was the revolution of 1905 called "the dress rehearsal for the 1917 revolution"?

a. the actors, the masses, peasant unions, and soviets, were all the same with unresolved issues.
b. the japanese were ready to battle again.
c. enough time had passed. the czar's image was no longer tarnished by bloody sunday.
d. the duma was a failure.

The correct answer is A) the actors, the masses, peasants unions and Soviets, were all the same with unresolved issues.

The Revolution of 1905 was called “the rehearsal for the 1917 Revolution” because the actors, the masses, peasants unions, and Soviets, were all the same with unresolved issues.

The Russian Revolution of 1905 was a period of conflict that included rebellions, strikes, peasants demands and military uprisings against the government of Russia. People from Russia demanded reforms that could impact their lives for the better. The revolts led to what was called the October Manifesto, that was a Constitutional reform and the creation of the Constitution and the political system of multi-parties.  

In reality, the reforms felt short and people didn’t receive major benefits. That is why the Revolution of 1905 was called “the rehearsal for the 1917 Revolution” because the actors, the masses, peasants unions, and Soviets, were all the same with unresolved issues.

b - those executed came from every social and economic class

political parties are protected under 6th amendment.
