The problem presented is a word problem that requires an explanation of the potential threats to the ruins of Mohenjodaro due to excavation. ### Known Conditions: 1. Mohenjodaro is an ancient city that was buried under dirt for centuries. 2. Archaeologists began to excavate the site, revealing important information. 3. The excavation process poses a threat to the ruins. ### Step-by-Step Explanation: 1. **Understanding the Context**: Mohenjodaro is an archaeological site that holds significant historical value. Excavation is necessary to uncover artifacts and structures that provide insights into ancient civilizations. 2. **Potential Threats from Excavation**: - **Structural Integrity**: The act of digging can destabilize the remaining structures. As layers of dirt are removed, the support for walls and buildings may be compromised, leading to collapses. - **Environmental Factors**: Excavation exposes the ruins to environmental elements such as rain, wind, and temperature changes, which can accelerate deterioration. - **Human Impact**: Increased human activity at the site can lead to vandalism or unintentional damage to delicate artifacts and structures. - **Loss of Context**: Excavating without proper methodology can result in the loss of archaeological context, making it difficult to understand the relationships between artifacts and their original settings. 3. **Conclusion**: While excavation is essential for uncovering the history of Mohenjodaro, it must be conducted carefully to mitigate risks to the integrity and preservation of the site. In summary, the excavation of Mohenjodaro, while revealing important historical information, threatens the ruins due to potential structural damage, environmental exposure, human impact, and loss of archaeological context.
