Alright, the user wants me to rewrite each word with three options in the word2 format. Let me start by understanding the original text. The first part is "Por que o Office 2007?" I need to make sure I replace each word with three synonyms.
Then "Antivírus" can be "programa de segurança", "proteção contra malware", and "software antimalware".
Wait, the user mentioned not to touch proper nouns. So "Office 2007" stays as is. Let me check each sentence. For example, "Lançado em 2007, o Office 2007 trouxe inovações significativas em termos de interface e funcionalidades, introduzindo a “Faixa de Opções” que simplificava a navegação pelos menus e ferramentas."
Double-check the replacements for correct grammatical gender and number. Also, ensure that the replacements are appropriate in a Portuguese context.
