Which of these was NOT a shared trait of early Harappan and Mesopotamian civilizations?

B cuneiform

To determine which of the options was not a shared trait of early Harappan and Mesopotamian civilizations, we can analyze each option individually and identify whether it was present in both civilizations.

a. Brick-walled cities: This option requires comparing whether both civilizations had cities built with brick walls. In this case, both the early Harappan and Mesopotamian civilizations had cities that were constructed using bricks. Therefore, option A is not the correct answer.

b. Cuneiform: This option refers to a writing system used by the Mesopotamians. Cuneiform writing was specific to the Mesopotamian civilization and was not used by the early Harappan civilization. Therefore, this option can be a potential correct answer.

c. Raised citadels: This option relates to fortified areas within cities that were elevated above the surrounding area. Both the early Harappan and Mesopotamian civilizations had raised citadels within their cities. Thus, option C is not the correct answer.

d. Origins along a major river: Both civilizations originated along major rivers. The early Harappan civilization developed along the Indus River, while the Mesopotamian civilization originated between the Tigris and Euphrates Rivers. Therefore, option D is not the correct answer.

Based on the analysis, option B, "cuneiform," is the correct answer since it was a trait unique to the Mesopotamian civilization and was not shared by the early Harappan civilization.
