Name two civilizations that arose along the Tigris and Euphrates; describe one cultural achievement.

• A. Egyptians and Hittites; pyramids and wheel invention
• B. Sumerians and Babylonians; Achievements include cuneiform writing and Hammurabi's Code
• C. Phoenicians and Assyrians; alphabet development and chariot warfare
• D. Harappans and Persians; grid cities and Zoroastrianism

Answer: (B)

The idea being tested is recognizing Mesopotamian civilizations that developed between the Tigris and Euphrates and identifying a key cultural achievement from that region. The two civilizations that fits this setup are the Sumerians and Babylonians, who thrived in the Mesopotamian plain between those rivers. A defining cultural achievement from this area is cuneiform writing, created by the Sumerians to keep records and manage administration, one of the earliest writing systems. Another landmark is Hammurabi's Code, compiled in Babylon, which shows how law and governance were organized in a sophisticated state.

Other options mix civilizations that did not both arise along these rivers: the Nile-based Egyptians, Anatolian Hittites, Levantine Phoenicians, Indus Valley Harappans, and Iranian Persians are from different regions. The listed achievements—cuneiform writing and Hammurabi's Code—are quintessential Mesopotamian innovations tied to the civilizations flourishing between the Tigris and Euphrates.
