Final answer:
Harappa and Mohenjo-Daro are celebrated for their sophisticated urban planning, characterized by grid-like street patterns, and their advanced drainage systems, demonstrating significant civil engineering skills and an understanding of public health.
Step-by-step explanation:
Harappa and Mohenjo-Daro are notable for their remarkable planning and urban design as well as their advanced drainage systems.
Urban Planning and Architecture
- The urban planning of these cities was well ahead of their time, marked by grid-like street patterns. This suggests a high level of administrative efficiency and civil engineering ingenuity. The orderly arrangement of the streets indicated rigorous city planning standards and a deep understanding of urban development.
Advanced Drainage Systems
- Another significant achievement is the advanced drainage systems. These systems reflect the complex understanding of hygiene and public health during the Indus Valley civilization. The presence of functional sewage systems is evidence of their advanced state of public utility management, setting them apart from their contemporaries.
