look at the picture. It shows the ruins of Mohenjo-Daro, one of the earliest cities of the Indus Valley civilization. What have scholars concluded about the civilization by looking at ruins such as these? What have they not been able to determine yet?

Oh, Mohenjo-Daro! The ruins of this ancient city have certainly puzzled scholars for years. From what they've gathered, they concluded that the Indus Valley civilization was highly advanced for its time, with well-organized urban planning, sophisticated architecture, and even a complex drainage system! Quite fancy for a civilization that predates smartphones, don't you think?

However, there are still a few things that have left scholars scratching their heads. Despite all their efforts, they haven't been able to decipher the writing system of the Indus Valley civilization. It's like trying to read an ancient grocery list with no context — pretty tricky! They also haven't figured out the exact reasons behind the downfall of these cities. Maybe they ran out of nachos? Who knows!

So, in a nutshell, scholars have made great strides in understanding the Indus Valley civilization, but there are still a few mysteries left to unravel. It’s like trying to solve a jigsaw puzzle without the box!

To understand what scholars have concluded about the Indus Valley civilization from ruins like those at Mohenjo-Daro, and what remains unknown, we need to examine the available evidence and ongoing research in the field.

1. Conclusions:
a) Urban Planning and Infrastructure: Scholars have observed that cities like Mohenjo-Daro were well-planned, with sophisticated systems of urban infrastructure. The presence of well-organized grid layouts, brick-lined streets, public and private wells, and advanced drainage systems indicate a high level of civic planning and engineering.
b) Water Management: The extensive water management system, including a complex network of canals, reservoirs, and wells, suggests the civilization's ability to manage water resources efficiently.
c) Trade and Commerce: The presence of dockyards and the discovery of seals and artifacts made from materials sourced from distant regions suggest a well-developed trade network and economic activity.
d) Writing System: The presence of a script known as the Indus script, found on seals and pottery, indicates a system of writing; however, scholars have not been able to decipher this script fully.

2. Open Questions:
a) Language and Writing: Despite efforts, scholars have not been able to decipher the Indus script, which limits our understanding of the language spoken in the Indus Valley civilization.
b) Political and Social Structure: The absence of monumental architecture, such as palaces or large temples, has led to debates about the civilization's political and social organization. It remains unclear whether it was a centralized state or a federation of smaller city-states.
c) Religion and Ideology: While many artifacts associated with religious practices have been found, the exact beliefs and religious practices of the Indus Valley civilization are not yet fully understood.
d) Causes of Decline: The precise reasons for the decline and eventual collapse of the Indus Valley civilization also remain speculative, with various theories proposed, such as natural disasters, environmental changes, or invasion.

In conclusion, while scholars have made significant progress in understanding the Indus Valley civilization by studying ruins like those at Mohenjo-Daro, several critical aspects of their society, such as their writing system, political structure, and religious practices, remain open to interpretation and further research.

Scholars have made several conclusions about the Indus Valley civilization by studying ruins such as the ones in Mohenjo-Daro. Here are a few of their findings:

1. Urban Planning: The careful layout and organization of the city's streets, buildings, and drainage systems suggest a high level of urban planning and architectural knowledge.
2. Advanced Sanitation: The presence of an elaborate drainage system and well-designed bathrooms with attached drainage pipes indicates a sophisticated understanding of sanitation and public health.
3. Trade and Economy: Excavations have revealed evidence of long-distance trade, including goods such as precious stones, metals, and pottery, which suggests that the civilization had a thriving economy and participated in trade networks.
4. Social Equality: The uniformity in architecture and the absence of grandiose palaces or temples suggest a level of social equality and a lack of centralized political power.

However, there are still many aspects of the Indus Valley civilization that scholars have not been able to determine conclusively, including:

1. Language and Writing: Despite finding thousands of inscriptions, the script used by the Indus Valley civilization remains undeciphered, leaving scholars unsure about the language spoken by its people.
2. Political System: The absence of substantial monumental architecture and inscriptions makes it difficult to ascertain the exact political structure, ruling elites, or whether there was a centralized authority.
3. Rituals and Religion: The lack of monumental temples or clear evidence of religious practices makes it challenging to understand the religious beliefs and rituals of the people.
4. Decline and Disappearance: The reasons for the decline and eventual disappearance of the Indus Valley civilization around 1900 BCE remain speculative, with no definitive explanation yet.

Further research and excavation work may shed more light on these unanswered questions in the future.
