Final answer:
The Harappans' advanced irrigation systems and standardized weights are two achievements that have parallels to modern engineering and commerce.
Step-by-step explanation:
Among the achievements of the Harappans, two that are comparable to modern times would be (A) their advanced irrigation systems and the use of standardized weights. The advanced irrigation systems developed by the Harappan civilization were crucial for their agriculture and urban planning, while standardized weights and measures facilitated trade and economic transactions. These practices foreshadow many of the systematic approaches used in contemporary civil engineering and commerce.
