Question

The tone of the passage is one of:

• A. informed concern.
• B. destructive criticism.
• C. derisive ridicule.
• D.

Hint:

Tone questions are best answered by focusing on whether the author offers solutions or just complains — solution-oriented writing is often “informed concern.”

Answer 1

The Correct Option is A

The passage discusses the serious issue of library book deterioration caused by acidic paper, presenting facts, causes, and possible solutions.
The author shows deep knowledge of the historical shift from rag-based paper to wood pulp, explains the chemical instability of acidic paper, and highlights statistics on current damage to collections.
At the same time, the author proposes practical remedies such as mass de-acidification, transferring content to other media, and switching to archival-quality paper.
This shows a tone of informed concern — the author is aware of the problem, understands its depth, and suggests solutions rather than simply expressing panic or blame.
Option (b) destructive criticism — is incorrect because the author does not simply attack libraries, publishers, or printers; instead, they aim for constructive change.
Option (c) derisive ridicule — is incorrect because there is no mocking or sarcastic tone present.
Option (d) helpless alarm — is incorrect because the author is not expressing hopelessness; they provide concrete ways to address the problem.
Therefore, (a) is the most accurate choice.
