Is it true that very little heat is lost through the roof?

  1. True

  2. False

The correct answer is: False

Highly reflective roofs can reduce the amount of heat absorbed by the building, thus potentially reducing energy usage. Additionally, well-insulated roofs can prevent heat from escaping, making the building more energy efficient. Therefore, it is not true that very little heat is lost through the roof. Option A is incorrect because it suggests that heat is not lost through the roof at all, which is not accurate. Heat can still be lost through roofs, just at a lower rate if the roof is properly insulated and reflective.
