• has trusses with a short truss span
• has trusses with a steep slope
• has trusses connected to partition walls
• has a poorly insulated attic
• is located in a warm climate

1. if a truss has been cut o

Explanation:

Truss uplift occurs when attic trusses expand due to temperature/humidity changes, pulling up on ceilings. A poorly insulated attic means the attic space (where trusses are) has more temperature/humidity fluctuations, leading to more expansion of trusses (like wood trusses expanding with moisture/heat). Short truss span, steep slope, connecting to partition walls, or warm climate alone don't directly drive truss uplift as much as poor attic insulation causing truss movement.

Answer:

Has a poorly insulated attic
