Two questions, not one
When the ASVAB asks about tone and purpose, it's really asking two different things:
- Tone — What attitude does the author's language reveal?
- Purpose — Why did the author write this? To inform, persuade, or describe?
Answer each separately. An informative passage can still have a warm tone. A persuasive passage can still present facts. Don't let one answer bleed into the other.
How to read for tone
Tone lives in adjectives, adverbs, and verbs. Neutral verbs: "states," "reports," "notes." Charged positive verbs: "excels," "achieves," "demonstrates." Charged negative verbs: "fails," "neglects," "undermines."
Sample passage:
The base's environmental initiative reduced water usage by 22% in its first year. Base leadership praised the program as a model for future sustainability efforts. Plans for expansion are already under review.
Tone: positive, favorable. The language ("praised," "model," "expansion") is approving but not exaggerated. Not neutral — the word "praised" is editorial. Not admiring to the point of reverence — just clearly positive.
Sample passage:
Water usage on base dropped 22% over the first year of the initiative. The program monitored daily consumption across 14 facilities and adjusted distribution accordingly. Results were submitted to regional command.
Tone: neutral, objective. Same topic, same facts — but zero editorial language. "Dropped," "monitored," "submitted" are all flat, factual verbs.
The three purposes
Inform — presents information without taking a side. Textbooks, instructions, announcements.
Persuade — argues for a position or course of action. Recommendation memos, editorials, op-eds.
Describe — creates a sensory or narrative picture. Rarely tested on the ASVAB but possible.
The quick check
When you finish reading, ask yourself: "Did the author use words that reveal how they feel about this?" If yes — tone is positive or negative, not neutral. Then ask: "Did the author argue for something, or just present facts?" That tells you the purpose.
Both answers come from the text, not from assumptions about the topic.
