After creating an effective research question, what should should a historian have? a. the answer to the research question b. a vague thesis with broad research goals c. the evidence needed to craft an argument d. a better understanding of potential research problems. plz

Hey there. I would think the best choice would be B. I say this because choice A is obviously not correct. Choice C well can't be true because the historian has no evidence. Choice D well after they create a question they are not going to get a better understanding of potential research problems. I hope this helped. :)

explanation:

workers got a five-day workweek because the bcea protects and respect the rights of the employees. labor leaders and other groups demanded it.
