In this task, you will be given a passage to read. A fill in the blank question will be given to you.  Your answer should fit the blank appropriately.

Example input: The music was composed by Hitoshi Sakimoto , who had also worked on the previous Valkyria Chronicles games . When he originally heard about the project , he thought it would be a light tone similar to other Valkyria Chronicles games , but found the themes much darker than expected . An early theme he designed around his original vision of the project was rejected . He redid the main theme about seven times through the music production due to this need to reassess the game . The main theme was initially recorded using orchestra , then Sakimoto removed elements such as the guitar and bass , then adjusted the theme using a synthesizer before redoing segments such as the guitar piece on their own before incorporating them into the theme . The rejected main theme was used as a hopeful tune that played during the game 's ending . The battle themes were designed around the concept of a  divorced from a fantasy scenario by using modern musical instruments , constructed to create a sense of atonality . While Sakimoto was most used to working with synthesized music , he felt that he needed to incorporate live instruments such as orchestra and guitar . The guitar was played by Mitsuhiro Ohta , who also arranged several of the later tracks . The game 's opening theme song ,  ( もしも君が願うのなら , Moshimo Kimi ga Negauno Nara ) , was sung by Japanese singer May 'n . Its theme was the reason soldiers fought , in particular their wish to protect what was precious to them rather than a sense of responsibility or duty . Its lyrics were written by Seiko Fujibayashi , who had worked on May 'n on previous singles . fill in the blank  : The music was composed by Hitoshi __________________ , who had also worked on the previous Valkyria Chronicles games
Example output: Sakimoto
Example explanation: This a good example. The actual line from the passage is The music was composed by Hitoshi Sakimotos, In the given sentence, it is stated clearly that Sakimoto answers the question correctly.
Q:  In addition to the reactions originally reported by Johnson , Corey , and Chaykovsky , sulfur ylides have been used for a number of related homologation reactions that tend to be grouped under the same name . With epoxides and aziridines the reaction serves as a ring @-@ expansion to produce the corresponding oxetane or azetidine . The long reaction times required for these reactions prevent them from occurring as significant side reactions when synthesizing epoxides and aziridines . Several cycloadditions wherein the ylide serves as a nucleophilic carbenoid equivalent  have been reported . Living polymerizations using trialkylboranes as the catalyst and ( dimethyloxosulfaniumyl ) methanide as the monomer have been reported for the synthesis of various complex polymers . fill in the blank  :  __________________ addition to the reactions orig__________________ally reported by Johnson , Corey , and Chaykovsky , sulfur ylides have been used for a number of related homologation reactions that tend to be grouped under the same name .
