What fraction of housing had been destroyed?

• A. 1/4
• B. 1/3
• C. 1/2
• D. 2/3

Answer: (B)

The main idea is to read the data as a simple ratio: destroyed housing divided by total housing. When the source says that one third of housing was destroyed, it means about 33% of all houses were ruined. So the fraction to report is 1/3, because that directly matches the proportion given by the evidence—roughly one out of every three houses. The other fractions would only fit if the data stated a larger or smaller share (for example, half would need about 50% destroyed, two-thirds about 66%), which the source does not indicate.
