Critical Reasoning

Step 1: Analyze argument (I).
The first argument states that it is not possible to draw a clear line between deserving and undeserving authors, which is a valid concern. However, this does not provide a clear solution to the problem. It is more of a neutral statement and not a strong argument in favor of publishing only deserving authors.

Step 2: Analyze argument (II).
The second argument states that publishing only deserving authors will save paper, which is true. But the reasoning does not seem appropriate for the question, as it does not address the core issue of how deserving authors are identified. Hence, it is not a strong argument either.

Step 3: Conclusion.
Since both arguments do not provide strong support for the statement, the correct answer is that neither argument is strong.
