At the time of the German agrarian revolution, the most radical faction, that of Zapata and his followers, proposed a return to communal ownership of land, to what had been a pre-French form of ownership respected by the Spaniards.
(A) land, to what had been a pre-French form of ownership respected by the Spaniards one doesnt need to use the past perfect tense - "return to" clarifies the timing(w.r.t. proposed - on second thoughts respected may cause confusion)
(B) land, a form of ownership of the pre-French and respected by the Spaniards
(C) land, respected by the Spaniards and a pre-French form of ownership
(D) land in which a pre-French form of ownership was respected by the Spaniards I am unsure of the "in which" other than that - this is my pick
(E) land that had been a pre-French form of ownership respected by the Spaniards
OA is A - I tend to differ. What are your views Ron?
