Name the Persian scholar renowned for his travels in India and his encyclopedic work on geography and science.

• A. Al-Biruni
• B. Al-Razi
• C. Hunayn ibn Ishaq
• D. Ibn Sina

Answer: (A)

This question tests recognition of a scholar who bridged cultures through direct travel and a sweeping, systematic work on geography and science. Al-Biruni traveled to India in the early 11th century, documenting languages, customs, astronomy, mathematics, geography, and various scientific and cultural practices. His major work, The Book of India (Kitab al-Hind), is an encyclopedic compendium that presents Indian knowledge and society in a rigorous, cross-cultural manner. This combination of firsthand travel and a comprehensive, interdisciplinary geography-and-science encyclopedia is what makes him the right figure. The other scholars are renowned for medicine, philosophy, or translation work rather than for long travels in India or for producing an extensive geographic-scientific encyclopedia.
