What is one reason that the middle ages are sometimes referred to as the dark ages?
a. for the fertile soil that supported agriculture
b. for the persecution suffered by certain christian groups as well as jews and muslims
c. for the political disorder that resulted from waves of invasions
d. for the heretical challenges leveled against the roman catholic church

I'd more likely to say that no of the given above fit to be the right. As there's not much information about middle ages. And that's why middle ages are associated with Dark Ages. But may be it's connected with religion, so the closest for me is b.for the persecution suffered by certain Christian groups as well as Jews and Muslims

the correct answer is d: "party organizers, volunteers, voters, and elected officials."

party organizers: individuals responsible for designing strategies in order to better execute the political campaign. this includes the candidate's public relations. volunteers: individuals responsible for raising awareness regarding the candidates running for office.voters: individuals who are convinced by volunteers that a particular candidate is the best option.elected officials: winning candidate and his elected team are a product of a successful political campaign.
