Question

Statements:
Only a few rivers are oceans.
All oceans are seas.
All seas are oceans.

Conclusion:
I. Some rivers are seas is a possibility.
II. All rivers are seas is a possibility.

• A. Neither I nor II follows
• B. Only I follows
• C. Either I or II follows
• D. Both I and II follow

Hint:

Remember the meaning of "Only a few A are B". It always implies both "Some A are B" and "Some A are not B". This is a key concept in modern syllogism questions.

Answer 1

The Correct Option is B

To solve this logical reasoning question, we need to analyze the given statements and see if the conclusions follow logically. Let's break down the statements and conclusions: 

1. Statements:
   • Only a few rivers are oceans.
   • All oceans are seas.
   • All seas are oceans.
2. Conclusions:
   • I. Some rivers are seas is a possibility.
   • II. All rivers are seas is a possibility.

Let's analyze the logical structure:

• The statement "Only a few rivers are oceans" indicates that some rivers can be oceans, but not all. This means there is at least one river that is an ocean.
• "All oceans are seas" implies that whatever is an ocean is also a sea, making every ocean a subset of seas.
• "All seas are oceans" implies a mutual inclusivity between seas and oceans, but logically it can lead to confusion in this context as generally, "all seas are oceans" seems logically incorrect unless considered in a specific philosophical or illustrative manner. Realistically, this is generally interpreted as an error unless justified.

Let’s see how the conclusions fit into this framework:

• Conclusion I: "Some rivers are seas is a possibility."
  Given "only a few rivers are oceans" and "all oceans are seas", it's possible for some rivers to be seas if those rivers that are oceans are automatically seas.
  Therefore, conclusion I is a possibility and follows.
• Conclusion II: "All rivers are seas is a possibility."
  This conclusion does not follow. Since only a few rivers are oceans, and therefore, not all rivers can become seas.
  Thus, conclusion II does not hold true as a possibility.

Hence, the only logical conclusion that follows is conclusion I. Therefore, the correct option is:

Option: Only I follows
