Worked Solution
Step 1: Analyze the requirements: holding 5kg (Strength) and folding into a pocket (Flexibility).
Step [2-9]: Evaluate the properties. Hardness, transparency, and buoyancy are irrelevant to these functions.
Step [2-9]: Therefore, both flexibility and strength are the critical properties.
Correct answer: Flexibility and Strength
