Question

Greg wants to build a tree house. He wants the house to last for a long time and to not be broken down by rain, snow, and wind. Which of the following would help Greg to choose a durable building material?
A.
Build one model of his tree house out of one type of material, and then freeze it in his freezer to see how well it holds up to the cold.
B.
Build his tree house out of several different materials, and see which part of the house holds up the longest.
C.
Build several models of his tree house out of different materials, and see which model holds up best to wind, water, and ice.
D.
Build his tree house out of the material that seems the strongest, and then test the material with water, ice, and wind.

Answer 1

C

Building several models from different materials and exposing them to the same wind, water, and ice conditions lets Greg directly compare durability across materials under the relevant weather stresses.
