Tin's early use dates back to:

• A. 3,500 B.C.
• B. 1,000 B.C.
• C. 500 A.D.
• D. 1000 A.D.

Answer: (A)

Tin is important in early metallurgy because it enables bronze, a stronger alloy made by combining copper with tin. The earliest bronze artifacts appear around 3,500 B.C., so tin’s use in metalworking is dated to roughly that time. The later dates—1,000 B.C. and 500 A.D.—come after bronze technology had already become widespread, so they don’t reflect the initial adoption of tin in alloying. Tin’s role also involved long-distance trade, since tin ore was not always available where copper was mined, helping bronze spread across ancient civilizations.
