Answer 1

1. The sun 2. An open gap 3. Tilted solar panels 4. Reflective roof membranes 5. Heating costs in the winter 6. An open gap 7. Whatever heat accumulated inside

Answer 2

## Step 1 The first blank in the passage is about what causes heat to be pushed through the roof. From the context, it is clear that the sun is the source of heat that is being pushed through the roof. ## Step 2 The second blank is about where air can circulate between the building and the solar panel. From the context, it is clear that the air can circulate between the building and the solar panel where there is an open gap. ## Step 3 The third blank is about the type of solar panels that are flush with the roof. From the context, it is clear that the solar panels that are flush with the roof are the tilted solar panels. ## Step 4 The fourth blank is about what can be used as a roof shade to reduce the heat reaching the roof. From the context, it is clear that reflective roof membranes can be used as a roof shade. ## Step 5 The fifth blank is about what the solar panels can help to reduce in the winter. From the context, it is clear that the solar panels can help to reduce heating costs in the winter. ## Step 6 The sixth blank is about what part of the roof is not covered by panels. From the context, it is clear that the part of the roof that is not covered by panels is the open gap. ## Step 7 The seventh blank is about what the solar panels can help to keep in at night. From the context, it is clear that the solar panels can help to keep in whatever heat accumulated inside.
