Justificação, hifenização

Question

Sou um estudante de doutorado e estou escrevendo sua tese no verso. Meu supervisor me disse para remover a hifenização, pois pode distrair, mas agora algumas palavras ultrapassam a margem (veja a foto). Alguém poderia me ajudar a modificar as configurações de justificação do verso ou talvez uma maneira diferente de resolver o problema? Meu preâmbulo é:
