Interviewer instructions
This question attempts to determine how smoke is directed out from the dwelling.
Do not confuse a chimney and a window or any other form of ventilation. The chimney is a structured construction aimed at directing out smoke. There are instances where a household uses a device to suck smoke fumes in place of a chimney; this should be considered as a chimney.
The interviewer is in most instances able to observe and confirm whether there is a chimney. Remember that some chimneys are structured in such a way that they emit smoke through the wall. Such chimneys are mostly constructed using mabati like materials.
