Final answer:
The French army invasion, colonization of other areas, and the invention of the printing press influenced how English became the official language in England.
Step-by-step explanation:
The key event in the book 'English: A Living Language' that influenced how English came to be the official language in England was the French army invasion. Despite the invasion, the English working class continued to speak English, which helped solidify its status as the primary language.
Additionally, as England colonized other areas, other cultures were exposed to the English language. This exposure led to English being adopted as the language of trade, diplomacy, and administration in those regions.
Furthermore, the invention of the printing press allowed books to be printed in English, increasing the availability and circulation of English texts and helping to establish English as the dominant language in England.
