答案 The diagram shows plans for a smokehouse, a kind of cooking shed, wherein food can be smoked and preserved. The project requires three holes to be dug and connected through underground piping; one for an air intake, one for the fire and one for the smoke itself, which runs up into a wider area and is diffused by a loose brick flooring. The air intake and fire are covered by movable lids and a well-sealed structure is placed over the chimney. First, food (in this case, fish) is placed in the smokehouse, then a fire is made and subsequently covered. The air intake is now lifted, both providing oxygen to the covered fire and blowing its smoke through the piping and up into the smokehouse itself. After a certain period of time, the food is ready to be brought back inside the house, to last through the cold winters of these strange people.
