Zorluk: KolayExtracting Supporting Details and Facts

An excerpt from an academic oral presentation on agricultural heritage restoration states: "To protect traditional wetland farming in southern Mexico City, researchers and local farmers collaborated to rehabilitate 45 active chinampa plots. As part of this initiative, the team installed biological filtration channels built from gravel and native tule reeds. Over a three-year period, these eco-friendly filters reduced heavy metal levels in irrigation water by 38 percent, ensuring safe soil conditions for organic vegetable cultivation."

According to the presentation, what specific action was taken across the 45 agricultural plots to improve water quality?

  1. A
    Transforming the entire historic wetland zone into a commercial wholesale market
  2. B
    Applying synthetic chemical purifiers to eliminate bacteria from the canals
  3. Installing biological filtration channels constructed from gravel and native reedsCevap
  4. D
    Constructing solid concrete barriers to permanently block all incoming irrigation flow

Cevap

Installing biological filtration channels constructed from gravel and native reeds
The presentation directly states that the researchers and farmers installed biological filtration channels made of gravel and native tule reeds to filter the water across the agricultural plots.
