Who were the “silent sentinels”? a group of progressive african americans who drafted the declaration of principles
anti-suffrage women
an offshoot of the industrial workers of the world
suffragists who protested outside the white house

The correct answer is D. Suffragists who protested outside the White House

Explanation:

The "Silent Sentinels" were a group of women that protest by using silence outside the White House on January of 1917 to show President Woodrow Wilson they supported women suffrage and therefore were suffragist as Woodrow did not support this. The group of women led protests every week for two years until the Nineteenth Amendment was passed and this ratified women could vote as any citizen could be denied to vote on the basis of gender. But unfortunately, during this time of protests, multiple cases of abuse and unfair arrest occurred against women. Therefore, the "Silent Sentinels" were basically female suffragists who protested outside the White House to try to defend and ratify their right to vote.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
