Archaeologists analyzing high-resolution synthetic aperture radar imagery of the Eastern Desert observed subsurface linear anomalies near ancient copper mines. Carbon dating of organic residue in nearby soil strata dates to the 12th century BCE. The researchers concluded that these linear anomalies represent buried irrigation canals constructed specifically to support the agricultural needs of the mining settlements.
Which of the following, if true, provides the strongest support for the researchers' conclusion?
- Soil samples extracted directly from inside the linear structures contain preserved pollen from cultivated grain crops that cannot survive in desert environments without artificial watering.Cevap
- BGeological surveys show that subterranean fault lines in the Eastern Desert naturally form linear patterns that trap organic sediment over centuries.
- CSynthetic aperture radar technology has been proven effective at detecting ancient subterranean trade routes in several other desert regions.
- DCopper smelting at the 12th-century BCE mining sites required substantial quantities of timber brought in from non-desert regions.
- EMetal production at the Eastern Desert mining settlements declined sharply towards the end of the 12th century BCE as local ore deposits became exhausted.
Cevap
The discovery of fossilized pollen from cultivated grain crops requiring artificial watering inside the linear structures provides direct empirical evidence that the anomalies were indeed irrigation canals built to support local agriculture.
The correct answer provides direct physical evidence connecting the subsurface linear structures to agricultural irrigation. Finding preserved pollen from crops that require artificial watering inside the features demonstrates that they functioned as water channels designed for crop cultivation, directly reinforcing the researchers' conclusion.
