Statements:

Only a few blue is red.

Some blue is pink.

Some pink is not yellow

Conclusions:

I. Some red is not pink

II. All red is pink

In each question below, some statements are given followed by some conclusions. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions definitely follows from the given statements, disregarding commonly known facts. Give answer:

Correct Answer: Either conclusion I or II follows

Step-by-Step Explanation:

Step 1: Analyze the Given Statements
1. Only a few blue is red: This means "Some blue is red" AND "Some blue is not red".
2. Some blue is pink: There is an intersection between the set of Blue and Pink.
3. Some pink is not yellow: A part of Pink lies outside Yellow.

Step 2: Evaluate Conclusion I and Conclusion II
Let's analyze the relation between Red and Pink:
- Statement 1 gives a relationship between Blue and Red.
- Statement 2 gives a relationship between Blue and Pink.
- There is no direct or definite relation given between Red and Pink in the statements.

Because there is no definitive connection given between Red and Pink, any direct claim about their relationship is uncertain:

Conclusion I: Some red is not pink (Particular Negative - type O)
Conclusion II: All red is pink (Universal Affirmative - type A)

Step 3: Apply Either-Or Conditions
For an "Either-Or" pair to exist between two conclusions, three conditions must be satisfied:
1. Both conclusions must be individually uncertain/false based on the given statements.
2. Both conclusions must contain the same subject ("Red") and predicate ("Pink").
3. The conclusions must form a complementary pair:
- "Some NOT" (Particular Negative) and "All" (Universal Affirmative) form a valid complementary pair (O + A pair).

Since all three conditions are satisfied between Conclusion I ("Some red is not pink") and Conclusion II ("All red is pink"), exactly one of them must be true at any given time.

Therefore, Either conclusion I or II follows.
