If several sediment traps occur along a drain, what does this indicate?
Answer and explanation
Correct answer: There was a planned arrangement to trap silt and waste and maintain the drains
The governing concept is organised drainage management. Sediment traps collected silt and solid waste before these materials entered or blocked the main channel, making inspection and cleaning easier. Several such features along one drain indicate deliberate maintenance planning rather than an accidental deposit. Therefore B is correct. A is too narrow because traps can serve wastewater systems as well, while C and D do not logically follow from the presence of traps.
