Where did lots of families go for shelter?

• A. Underground stations
• B. Public shelters
• C. Banks of rivers
• D. Parks

Answer: (A)

In WWII, civilians needed a safe place quickly during air raids. Underground stations offered the strongest protection because they are deep underground and built to withstand blast, heat, and falling debris. They could shelter large numbers of families in safety rooms, corridors, and platforms, making them the most practical option for staying safe through raids. Other choices like public shelters, banks of rivers, or parks were less protective and exposed people to the dangers outside, so they weren't used as widely or for as long.
