    "purpose": "Let an agent explain rock sheds, relay design, materials, locations and hazard management from geotechnical and road engineering sources, and distinguish rock sheds from tunnels, avalanche galleries, rockfall nets and retaining walls.",
    "definition": "A protective structure built over a road or railway on a mountainside to shield traffic from falling rocks, and often also avalanches and debris flows, usually a reinforced concrete or steel gallery with a roof and an open or partly open valley side, sometimes covered with cushioning soil layers that absorb impact energy; related avalanche and snow sheds are common in the Alps, Japan, Norway and western North America, as at Rogers Pass in Canada. Design considers impact energy, maintenance and drainage, and road users should obey closure signs during rockfall and avalanche warnings.",
