A significant amount of the acquisition budget of a typical university library is spent on subscriptions to scholarly journals. Over the last several years, the average subscription rate a library pays for such a journal has increased dramatically, even though the costs of publishing a scholarly journal have remained fairly constant. Obviously, then, in most cases publishing a scholarly journal must be much more profitable now than it was several years ago.
Which one of the following, if true, most seriously weakens the argument?
(A) Many university libraries have begun to charge higher and higher fines for overdue books and periodicals as a way of passing on increased journal subscription costs to library users.
(B) A university library's acquisition budget usually represents only a small fraction of its total operating budget.
(C) Publishing a scholarly journal is an expensive enterprise, and publishers of such journals cannot survive financially if they consistently lose money.
(D) Most subscribers to scholarly journals are individuals, not libraries, and the subscription rates for individuals have generally remained unchanged for the past several years.
(E) The majority of scholarly journals are published no more than four times a year.

A significant amount of the acquisition budget of library is spent on subscriptions to scholarly journals.
Over the last several years, the average subscription rate a library pays for such a journal has increased dramatically,
Costs of publishing a scholarly journal have remained fairly constant.
Conclusion: In most cases publishing a scholarly journal must be much more profitable now than it was several years ago
The argument says that costs of publishing have remained same but subscription rate has increased dramatically. So the argument is concluding that publishing a journal must be more profitable now. We need to weaken this:
(A) Many university libraries have begun to charge higher and higher fines for overdue books and periodicals as a way of passing on increased journal subscription costs to library users.
Irrelevant how the library pays higher subscription. We need to focus on costs and revenues of journals.
(B) A university library's acquisition budget usually represents only a small fraction of its total operating budget.
Again, a library's budget is irrelevant to us. We need to focus on costs and revenues of journals.
(C) Publishing a scholarly journal is an expensive enterprise, and publishers of such journals cannot survive financially if they consistently lose money.
We know that costs have remained same and subscription rate has increased. How much exactly is the cost is irrelevant.
(D) Most subscribers to scholarly journals are individuals, not libraries, and the subscription rates for individuals have generally remained unchanged for the past several years.
Correct. So the cost has remained the same but it seems that the revenues haven't increased much either. If most subscriptions are of individuals and their rate has remained same, the overall revenue may not have increased much either. Hence the profits may not be much more now.
(E) The majority of scholarly journals are published no more than four times a year.
No of times they are published is irrelevant. Fewer publications means less cost too.
Answer (D)
