During field training, soldiers must follow a strict four-step procedure to purify untreated creek water. First, strain the turbid water through a clean cloth filter to remove large sediment and floating debris. Second, bring the strained water to a rolling boil for at least three full minutes to neutralize harmful biological pathogens. Third, allow the boiled water to cool down completely in a shaded container. Finally, add purification tablets to ensure long-term residual disinfection before drinking.
Based on the passage, match each procedural stage to its correct operational action.
- First stageStrain turbid water through cloth to remove sediment
- Second stageBoil the water for three minutes to destroy pathogens
- Third stageAllow the water to cool completely in shade
- Final stageAdd purification tablets for residual disinfection
Cevap
First stage matches straining water through cloth; second stage matches boiling for three minutes; third stage matches allowing water to cool in shade; final stage matches adding purification tablets.
The correct matches follow the explicit chronological markers provided in the text: 'First' introduces cloth straining, 'Second' describes three minutes of boiling, 'Third' mentions cooling in the shade, and 'Finally' designates adding purification tablets.
