Option 1 -> This is a literal interpretation; the text uses "timeless" metaphorically, not to suggest physical immortality.
Option 2 -> The archaeologist "lived a thousand years behind the times" and cared nothing for basic needs like food or shelter—only for ancient artifacts, showing complete absorption in the past.
Option 3 -> The archaeologist studies ancient history, not the future; this contradicts his work and character.
Option 4 -> The text explicitly states he "wanted neither food, roof or riches," indicating wealth wasn't his concern or defining trait.
Hence, Option 2 -> The phrase "timeless being" combined with "lived a thousand years behind the times" reveals the archaeologist was so consumed by ancient history that modern concerns were irrelevant to him—he existed mentally in another era -> correct
