Imagine you are going to conduct a research project based on this excerpt. Which research question is the most effective for this topic?

The question is incomplete and the full version can be found online.  

How did suffragettes work to obtain the rights outlined in the Seneca Falls Declaration of Sentiments?

Explanation:

The question refers to the Declaration of Sentiments (New York, July 1848), the document that arose from the Seneca Falls Convention to demand citizens' rights for American women and denounce the oppression they were subjected to by the government and the patriarchal society.

Out of the options provided, the most effective research question for this topic would be the one inquiring about the steps taken by the suffragettes to obtain those rights, as it would allow an analysis of their political movement and its result.

The option inquiring about the grievances included in the declaration wouldn´t require research beyond reading the text, so it wouldn´t be an effective research question.

The option inquiring about other women's rights conventions would be an interesting question, but not the most effective if we want to focus on this declaration.

And the option inquiring about the effect of the Declaration is too general, so it wouldn´t be as effective as the chosen answer.
