Source 1 (Print Summary): An environmental engineering article evaluates the restoration of pre-Inca *amunas* (ancestral stone infiltration channels) in the highlands of Huarochirí, Peru. The author concludes that while *amunas* provide a highly cost-effective, low-carbon method for recharging mountain aquifers and stabilizing dry-season river flow, they cannot replace modern reservoirs during peak flood events due to their slow infiltration rates and limited surge capacity.
Source 2 (Audio Summary): A regional radio broadcast interviews a local water board leader and an agroecologist in the Lima highlands. The speakers emphasize that reviving *amunas* succeeds primarily because it relies on communal governance (*minka*) and strengthens intergenerational cultural identity, warning that municipal attempts to commercialize or manage the canals through centralized state agencies disregard the essential social fabric that maintains them.
Based on the summaries, which of the following best contrasts the primary perspectives of the two sources regarding the revitalized *amuna* systems?
- AThe print source prioritizes the cultural and communal organization behind the canals, whereas the audio source focuses on quantifying hydrological infiltration rates and storage limits.
- The print source evaluates the canals through their technical and infrastructural capabilities, whereas the audio source emphasizes the indispensability of community stewardship and cultural cohesion.Answer
- CThe print source argues that traditional canals are entirely obsolete compared to modern dams, whereas the audio source claims ancestral systems make all modern reservoir infrastructure unnecessary.
- DThe print source warns that centralized municipal control will degrade the waterways, whereas the audio source advocates replacing communal labor with state management.
