English Tone and Formality: TEAS Practice Question with Answer & Explanation

Formal vs. Informal Tone in Academic Writing

In the TEAS English and Language Usage section, you will be tested on your ability to recognize standard English conventions and the appropriate tone for specific contexts. Academic, medical, and scientific writing require an objective, precise, and formal tone.

Why Choice B is Correct

The word "stuffy" is the correct answer because it is a colloquial (informal) term. In a professional medical report, researchers should avoid vague, "everyday" language that relies on subjective feeling. Instead of saying a room was "stuffy," a formal report would use precise terminology like "inadequate ventilation," "poor air circulation," or "increased carbon dioxide levels."

Analysis of Incorrect Options

• A: Preliminary. This is an appropriately formal adjective used to describe data or findings that are initial or introductory. It is common and accepted in scientific literature.
• C: Findings. This is a standard academic term referring to the results of an investigation or study. It fits perfectly within the context of a research report.
• D: Adverse. This is a formal medical term often used to describe harmful or unfavorable effects (such as "adverse reactions"). It is much more appropriate than informal alternatives like "bad" or "unpleasant."

The TEAS Concept: Register and Context

When evaluating tone on the TEAS, ask yourself: Who is the audience, and what is the purpose?

1. Peer-reviewed journals/Medical reports: Demand objective, technical, and precise language.
2. Professional emails: Demand polite, standard English without slang.
3. Creative writing/Personal blogs: Allow for idioms, contractions, and figurative language (like "stuffy" or "way too").

Memory Tip

To identify informal language, look for words you might use when texting a friend or talking to a family member at dinner. If the word describes a feeling or a "vibe" rather than a measurable fact, it is likely too informal for a medical journal. Phrases like "kind of," "way," "pretty much," and "stuff" are major red flags in formal writing.
