Although a number of excellent studies narrate the development of domestic technology and its impact on housewifery, these works do not discuss the

the women employed 'by the manufacturers' [A,D,E] vs 'to be product demonstrators by manufacturers' [B, C]: If we delay the prepositional phrase 'by the manufactures' a lot of other nouns come in between that cause the question are the women employed by the manufacturers or the demonstrators by the manufacturers. As the modifier by the manufacturer conveys key info about which women it it preferred it stay near it. Unless ADE have seriously big oopsies we'll keep those as on top. COme to B, C only if A, D, E are for sure wrong.
