The exercise is to decide whether the question accepts the proposed suggestion as a correct answer. If yes, write "True", otherwise write "False".
Question: how long is a flat membrane roof good for?
Suggestion: In areas where the roof could become saturated by rain and leak, or where water soaked into the brickwork could freeze to ice and thus lead to 'blowing' (breaking up of the mortar/brickwork/concrete by the expansion of ice as it forms) these roofs are not suitable.
