Explanation

To solve the analogy "Good : Bad :: Roof : ?", we need to identify the relationship between the first pair of words and apply that same relationship to the second pair.

### Step-by-step Solution:

1. **Identify the Relationship in the First Pair:**
- The words "Good" and "Bad" are antonyms. This means they have opposite meanings.

2. **Identify the Relationship for the Second Pair:**
- We need to find a word that has an opposite relationship to "Roof".

3. **Understanding the Term "Roof":**
- A roof is the top covering of a building or structure. It is positioned at the highest point.

4. **Consider Possible Options:**
- The options given are:
- Option 1: Window
- Option 2: Floor
- Option 3: Walls
- Option 4: Pillars

5. **Analyze Each Option:**
- **Window:** A window is not at the bottom; it is typically found in the walls of a building.
- **Floor:** The floor is the bottom part of a building, which is the opposite of the roof.
- **Walls:** Walls are vertical structures that support the roof but are not at the bottom.
- **Pillars:** Pillars are vertical supports and do not represent the bottom part of a structure.

6. **Determine the Correct Answer:**
- Since "Floor" is the only option that represents the bottom part of a building, which is opposite to the roof, it is the correct answer.

### Final Answer:
The answer to the analogy "Good : Bad :: Roof : ?" is **Floor**.
