Statements: 1. All windows are needles
2. Some trees are windows
Conclusions: 1. Some trees are needles
2. Some trees are not needles

Options

A. only conclusion 1 follows,
B. only conclusion 2 follows,
C. either conclusion 1 or 2 follows,
D. neither conclusion 1 nor 2 follows,

Answer

To solve the problem, we need to analyze the given statements and conclusions logically.

### Step-by-Step Solution:

1. **Understanding the Statements:**
- **Statement 1:** All windows are needles.
- This means that every window is included in the category of needles.
- **Statement 2:** Some trees are windows.
- This indicates that there is at least one tree that is also a window.

2. **Visual Representation:**
- Let's represent the statements using Venn diagrams:
- Draw a large circle for needles.
- Inside this circle, draw a smaller circle for windows (since all windows are needles).
- Now, draw another circle for trees that overlaps with the window circle, indicating that some trees are windows.

3. **Analyzing Conclusion 1:**
- **Conclusion 1:** Some trees are needles.
- Since some trees are windows and all windows are needles, it follows that those trees that are windows must also be needles.
- Therefore, this conclusion is **true**.

4. **Analyzing Conclusion 2:**
- **Conclusion 2:** Some trees are not needles.
- We cannot definitively determine this from the statements provided. While some trees are windows (and thus needles), we do not know if there are trees that are not windows.
- Therefore, this conclusion is **not necessarily true**.

5. **Final Evaluation:**
- Based on the analysis:
- Conclusion 1 is true.
- Conclusion 2 is false.
- Thus, only Conclusion 1 follows from the statements.

### Final Answer:
Only conclusion 1 is true.
