By what year was English spoken by about 400 million people, leading to new varieties?

• A. 1066
• B. 410 AD
• C. 1583
• D. 1800

Answer: (C)

The idea being tested is how a language’s global spread leads to regional varieties. When English began to be used far beyond Britain—through exploration, trade, printing, and colonization—different communities started adapting it to their own sounds, norms, and needs. The late 16th century marks the period when English began to be spoken widely across the world enough to seed these divergent forms. The year around 1583 sits in this window, making it the most fitting moment for the emergence of new varieties as English spread. The earlier date is too early to reflect this global diffusion, while the later date doesn’t align with the initial global spread that drove diversification.
