2. 2.

   What is the purpose of raft foundations?

   Hint

   Imagine a table with many legs to distribute its weight.

3. 3.

   What is the main purpose of deep foundations?

   • To enhance aesthetics
   • To reach stable soil layers
   • To reduce construction costs

   Hint

   Think about what happens if a building sits on unstable ground.

4. 4.

   True or False: Raft foundations are used to concentrate loads in a small area.

   • True
   • False

   Hint

   Picture a legion of ants carrying an evenly distributed load.

5. 5.
