Worked Solution
Step 1: Identify the action (pushing the plunger) and the observation (volume decreased).
Step [2-9]: Understand that solids and liquids have definite volumes and cannot be compressed significantly.
Step [2-9]: Since the volume of the trapped air could be reduced, it shows air is compressible.
Correct answer: Air can be compressed.
