Final answer:
Preservation of archaeological sites, precision in data collection, and direct observation of historical contexts are benefits of survey over excavation.
Step-by-step explanation:
B) Preservation of archaeological sites is a benefit of survey over excavation. By conducting surveys, archaeologists can identify potential sites and determine their significance before excavation takes place. This helps to preserve the sites and protect them from unnecessary disturbance.
C) Precision in data collection is another benefit. Surveys allow archaeologists to collect data from a larger area, providing a more comprehensive understanding of the site. This precision in data collection contributes to accurate analysis and interpretation of the artifacts and features.
E) Direct observation of historical contexts is also a benefit. During a survey, archaeologists can observe the surrounding landscape and context in which the artifacts are found. This observation provides valuable information about the historical context and helps to reconstruct the past.
