Questions 1 to 5 (questions 1 to 5)

1. What is the single most important factor that should shape how a technical document is written? The Audience and Its Needs. Technical writing is reader-centered. Everything, the word choice, the level of detail, the structure, follows from who will read the document and what they need to do with it.

2. In the technical writing process, the planning stage that comes before drafting is best described as: Analyzing the Audience and Defining the Purpose. Good documents start with analysis, not words. You first decide who the readers are and what the document must accomplish, then you draft, then you revise and edit.

3. A document written for expert engineers versus one written for the general public should differ mainly in its: Level of Technical Vocabulary and Detail. When you know more about your readers, you adjust the technical vocabulary and depth. Experts can handle jargon and dense detail, while a general audience needs plain language and more explanation.

4. The primary goal of most technical writing is to: Inform the Reader Clearly and Help Them Complete a Task. Technical writing exists to convey information clearly and accurately so the reader can understand a subject or perform a task. Clarity and usefulness matter far more than style or flourish.

5. When a writer adapts the same information differently for a manager, a technician, and a customer, the writer is responding to differences in: Audience. One set of facts can require three different documents because each audience has different background knowledge and different reasons for reading. Adapting to the audience is the heart of the craft.

Questions 6 to 10 (questions 6 to 10)

6. A document that gives step-by-step directions for operating a piece of equipment is best classified as: A Set of Instructions. Instructions, the how-to documents, lead a reader through a task one numbered step at a time. A user manual is built largely from sets of instructions.

7. A short summary placed at the start of a long technical report so a busy reader can grasp the key points without reading the whole thing is called: An Executive Summary. An executive summary condenses a report's purpose, findings, and recommendations into a brief overview aimed at decision-makers who may never read the full document.

8. A document written to convince a reader to approve a project, fund an idea, or hire a company is a: Proposal. A proposal argues that a problem exists and that the writer's plan is the best way to solve it. It is persuasive by design, unlike a neutral report or a set of instructions.

9. Which document type is normally used for brief, routine communication inside a single organization? A Memo. The memo, short for memorandum, is the standard format for internal messages such as announcements, short reports, and requests. Email has largely taken over its role but follows the same conventions.

10. An alphabetical list of specialized terms and their definitions, placed at the back of a technical document, is a: A Glossary. A glossary defines the technical terms a document uses so readers unfamiliar with the jargon can look them up. It supports, rather than replaces, plain language in the main text.

Questions 11 to 15 (questions 11 to 15)

11. Which sentence best follows the technical writing preference for the active voice? The Operator Closed the Valve. Active voice names the doer and the action directly, which is shorter and clearer. Passive constructions hide who acts and add words, so technical writing favors the active voice.

12. To make a procedure easier to follow, the steps are most effectively presented as: A Numbered List in the Order the Steps Are Performed. Sequential actions belong in a numbered list that mirrors the order of the task. Numbering signals sequence, and one action per step keeps the reader from getting lost.

13. In technical writing, using short, common words instead of long, unusual ones is recommended because it: Improves Clarity and Readability for the Audience. Plain, familiar words communicate faster and to a wider audience. Inflated vocabulary slows readers and risks misunderstanding, which defeats the purpose of a technical document.

14. Which of the following is the clearest, most concise revision of the wordy phrase "in the event that"? If. Conciseness means cutting empty phrases. 'In the event that' simply means 'if,' and replacing it removes clutter without changing the meaning.

15. Instructions are usually written using which kind of verb form to tell the reader what to do? The Imperative (command) Form. Steps in instructions use the imperative, direct commands such as 'press,' 'turn,' and 'remove.' The command form speaks straight to the reader and keeps each step short.

Questions 16 to 20 (questions 16 to 20)

16. A graphic that is best for showing how parts of a whole compare as percentages is a: Pie Chart. A pie chart divides a circle into slices that represent each part's share of the whole. It is the natural choice when the data add up to one hundred percent.

17. To show a trend or change in a value over a period of time, the most appropriate graphic is a: Line Graph. A line graph plots data points across time and connects them, making rises, falls, and trends easy to see at a glance. That is why it suits time-series data.

18. In page design, generous use of white space, headings, and lists is intended mainly to: Help Readers Find and Scan Information Easily. Design elements such as white space, headings, and lists guide the eye and let readers locate what they need quickly. Good page design serves usability, not decoration.

19. Presenting borrowed material as your own work without giving credit to the original source is called: Plagiarism. Plagiarism is using someone else's words, data, or ideas without attribution. Ethical technical writing requires citing sources, and avoiding plagiarism protects both honesty and credibility.

20. An ethical technical writer presenting data from a study should: Report the Data Accurately, Including Results That Are Inconvenient. Honesty is a core obligation in technical communication. Writers must present data truthfully and completely, even when some results are unfavorable, because readers rely on it to make decisions.

What to do with your score

The point of twenty questions is not the twenty, it is the pattern. Mark which topic each miss came from, then spend your next session on that topic alone. None of it requires starting over, only tightening the spots that cost you points.

A single twenty-question set is a snapshot, not a study plan. To pass with margin you need volume: enough questions, in the exam's format, with explanations that turn a wrong answer into a correction. That is what Flying Prep's DSST Technical Writing practice is built for: every question explained, with a free trial before you decide.
