Detailed Solution

The glass that is completely full of water has more water than the half-full glass, assuming both glasses are of the same size and capacity.

Explanation (Step-by-Step Reasoning):

Understanding the Problem:
- We are comparing two glasses of water.
- One glass is “full” (100% capacity).
- The other glass is “half-full” (50% capacity).
- The key assumption here is that both glasses are identical in size.
Mathematical Perspective:
- If a glass holds X milliliters of water when full, then:
  - Full glass = X ml
  - Half-full glass = X/2 ml
- Clearly, X > X/2, so the full glass has more water.
Critical Thinking:
- If the two glasses are of different sizes, the answer could change.
- Example: A half-full jug may contain more water than a full small cup.
- But since the question typically implies same type of glasses, the straightforward answer is the full one.
