Statements : Some papers are pens. Angle is a paper. Conclusions : I. Angle is not a pen. II. Angle is a pen.

The correct answer is: Only conclusion II follows.

The first statement, “Some papers are pens,” means that there exists at least one paper that is also a pen. The second statement, “Angle is a paper,” means that Angle is a paper.

From these two statements, we cannot conclude that Angle is not a pen. It is possible that Angle is a pen, since the first statement tells us that some papers are pens. However, we also cannot conclude that Angle is a pen. It is possible that Angle is a paper that is not a pen.

Therefore, only conclusion II follows. Conclusion I does not follow, since it is possible that Angle is a pen.

Here is a more detailed explanation of each option:

• Option A: Only conclusion I follows. This option is incorrect, since conclusion II also follows.
• Option B: Only conclusion II follows. This option is correct.
• Option C: Either I or II follows. This option is incorrect, since only conclusion II follows.
• Option D: Neither I nor II follows. This option is incorrect, since conclusion II follows.
• Option E: Both I and II follow. This option is incorrect, since only conclusion II follows.
