By 1400, Muslim societies spanned the central five-eighths of Afro-Eurasia. true or false

I believe that the answer is true because the question says that by 1400, Muslim societies spanned the central five - eights of Afro-Eurasia which is accurate. During the 1400s, new little Muslim town were starting to appear all over West Africa, East African Coast, India, Southeast Asia, and Central Asia.
