Clive wants to build a house that is safe from floods. He is considering either building the house on a raised platform or installing a metal roof. Which of these options will be the most effective in protecting the house against flooding?

Question

A.
building the house on a raised platform so that it drains the flood water faster
B.
installing a metal roof to prevent flood water from entering the house
C.
installing a metal roof so that minimum damage is done to the house
D.
building the house on a raised platform to prevent flood water from entering the house

Answer 1

The most effective option for protecting the house against flooding is:

D. building the house on a raised platform to prevent flood water from entering the house.

Building on a raised platform elevates the house above potential flood levels, significantly reducing the risk of water entering the structure during a flood. While installing a metal roof can help minimize damage from rain and debris, it does not prevent flood waters from entering the house as effectively as raising the house would.
