[EX Q]:  The structure of Dominican society was hierarchical , with strongly gendered roles . Rafael Trujillo , the ruler , was a cruel dictator who haunts the people of Santo Domingo even 35 years after his death . He is a true caudillo , ruling with brutality and corruption . He creates a personality cult in his capitalist society and encourages decadence within his regime . Prior to promotion to a position of responsibility , an officer is required to pass a test of loyalty  . His people are to remain loyal to him all cost , and are periodically tested by public humiliation and censure even though acts of disloyalty were rare . Trujillo violates women and children as an expression of political and sexual power , and in some cases takes the wife or child of his lieutenants , many of whom still remain blindly loyal . Even the church and military institutions are employed to give women to the tyrant for pleasure . Many of the assassins had belonged to the Trujillo regime or had at one point been its staunch supporters , only to find their support for him eroded by the state 's crimes against its people . Imbert , one of the assassins , sums up this realization in a comment prompted by the murder of the Mirabal sisters :  They kill our fathers , our brothers , our friends . And now they 're killing our women . And here we sit , resigned , waiting our turn .  In an interview , Vargas Llosa describes the corruption and brutality of Trujillo 's regime :  He had more or less all the common traits of a Latin American dictator , but pushed to the extreme . In cruelty , I think he went far far away from the rest — and in corruption , too .  fill in the blank  :  The structure of Dominican society was hierarchical , with strongly __________________ roles .

[EX Q]:  The original publication by Johnson concerned the reaction of 9 @-@ dimethylsulfonium fluorenylide with substituted benzaldehyde derivatives . The attempted Wittig @-@ like reaction failed and a benzalfluorene oxide was obtained instead , noting that  Reaction between the sulfur ylid and benzaldehydes did not afford benzalfluorenes as had the phosphorus and arsenic ylids .  The subsequent development of ( dimethyloxosulfaniumyl ) methanide , ( CH3 ) 2SOCH2 and ( dimethylsulfaniumyl ) methanide , ( CH3 ) 2SCH2 ( known as Corey – Chaykovsky reagents ) by Corey and Chaykovsky as efficient methylene @-@ transfer reagents established the reaction as a part of the organic canon . fill in the blank  :  The original publication by Johnson concerned the reaction of 9 @-@ __________________ fluorenylide with substituted benzaldehyde derivatives .
