Explanation
Correct answer: C.
Choice C is the best answer. “To that end” logically signals that the information in this sentence—that Dowsett founded the National Women’s Equal Suffrage Association of Hawai‘i—describes an action Dowsett took to achieve the goal stated in the previous sentence: to coordinate the efforts of suffragists in Hawai‘i.
Why the other choices are wrong
Choice A
Choice A is incorrect because “in other words” illogically signals that the information in this sentence about Dowsett founding a women’s suffrage association is a paraphrase or restatement of the previous information about Dowsett seeking to coordinate suffragists’ efforts. Instead, the sentence describes a specific action Dowsett took to achieve this goal.
Choice B
Choice B is incorrect because “conversely” illogically signals that the information in this sentence about Dowsett founding a women’s suffrage association contrasts with the previous information about Dowsett seeking to coordinate suffragists’ efforts. Instead, the sentence describes a specific action Dowsett took to achieve this goal.
Choice D
Choice D is incorrect because “alternatively” illogically signals that the information in this sentence about Dowsett founding a women’s suffrage association presents an alternative to her seeking to coordinate suffragists’ efforts. Instead, the sentence describes a specific action Dowsett took to achieve this goal.
