Red Seal Carpenter Practice Exam

When rafters are placed opposite each other and ceiling joists are supported on a bearing wall, the joists are typically installed by setting them on opposite sides of the rafters and lapping them over the bearing wall. They are then spaced with a block and nailed together to provide support. Option A is incorrect because the joists are not typically placed on the same side and butted together. Option B is also incorrect because the joists are not usually lapped over the bearing wall in this way. Option D is incorrect because it describes a similar method as option A, but with lapping instead of butting.
