In the following question, some statements are given followed by two conclusions. You must assume the statements to be true even if they contradict commonly known facts. Read the conclusions and decide which of the conclusions logically follows from the statements.

Statements:
Only a few P is Q
No Q is R
All R is S.
Conclusions:
I. Some S is not Q
II. All P can be R

Correct Answer: If only conclusion I follows

Let us analyze the given statements and check the validity of each conclusion step-by-step.

Given Statements:

1. Only a few P is Q: This means that some P are Q, and some P are definitely not Q.
2. No Q is R: There is no intersection between the set Q and the set R.
3. All R is S: The entire set R is contained within the set S.

Evaluating Conclusion I: Some S is not Q

From statement 3, we know that all of R is inside S ($R\subseteq S$).
From statement 2, we know that no Q is R, which also means no portion of R can ever overlap with Q.
Since the entire region of R lies inside S, that portion of S which is R can never be Q.
Therefore, the elements of S that belong to R will never be part of Q, which proves that Some S is not Q is definitely true.

Evaluating Conclusion II: All P can be R

From statement 1 ("Only a few P is Q"), it is established that some part of P is definitely inside Q.
From statement 2 ("No Q is R"), no element of Q can touch or overlap with R.
Since a portion of P is permanently inside Q, that specific portion of P can never be part of R.
Therefore, it is impossible for All P to be R. Hence, conclusion II does not follow.

Conclusion:

Only conclusion I logically follows from the given statements.
