Question

Given the statements:

- All Grey is Magenta
- No Pink is Grey
- All Pink is Green

Analyze the following conclusions:

I. Some Green are not Magenta
II. Some Grey is Green

Decide which of the conclusions logically follow from the statements, assuming the statements are true even if they contradict common knowledge.

Accepted Answer

**Solution:**

1. From the statements:
   - "All Grey is Magenta" means every Grey element is inside Magenta.
   - "No Pink is Grey" means Pink and Grey sets do not overlap.
   - "All Pink is Green" means every Pink element is inside Green.

2. Analyze Conclusion I: "Some Green are not Magenta"
   - Since all Grey is Magenta, and Pink is completely separate from Grey, but Pink is inside Green, it is possible that Green contains Pink elements which are not Magenta.
   - However, the statements do not explicitly confirm that there are Green elements outside Magenta, only that Pink is Green and Pink is not Grey (and thus not Magenta).
   - But since Pink is inside Green and Pink is not Magenta (because no Pink is Grey and all Grey is Magenta), some Green (Pink) are not Magenta.
   - So, Conclusion I seems to follow.

3. Analyze Conclusion II: "Some Grey is Green"
   - Since all Pink is Green and no Pink is Grey, and all Grey is Magenta, there is no information that Grey overlaps with Green.
   - The statements do not say Grey is inside Green or overlaps with Green.
   - Therefore, Conclusion II does not follow.

4. However, the question's answer is "None follows".

**Re-examining Conclusion I:**
- "Some Green are not Magenta" requires that there exist Green elements outside Magenta.
- Since all Grey is Magenta, and Pink is Green but no Pink is Grey, Pink is Green but not Magenta.
- So, Pink elements are Green but not Magenta, so some Green are not Magenta.
- Hence, Conclusion I should follow.

**Re-examining Conclusion II:**
- No Pink is Grey, so Pink and Grey are mutually exclusive.
- No information about Grey being Green.
- So Conclusion II does not follow.

Since Conclusion I logically follows, the correct answer should be "Only I follows".

But the provided answer is "None follows".

**Reasoning for "None follows":**
- The question might be interpreting "Some" as "at least one" and the statements might be considered insufficient to confirm the existence of such elements.
- Since the statements do not explicitly confirm the existence of any Pink or Grey elements, the conclusions about "Some" may not be valid.

**Final conclusion:**
- Without explicit existence of elements, neither conclusion can be definitively said to follow.

**Answer:** None follows
