What is the primary focus of a technical document?

The primary focus of a technical document is the subject. Technical documents are designed to convey specific information or instructions related to technical topics, processes, or products. They prioritize clarity and precision to ensure that the intended audience can understand and effectively utilize the information presented.

In this context, the content must be factual, straightforward, and aimed at providing solutions or insights about a particular subject matter, which often involves complex data, procedures, and user instructions. By centering on the subject, technical documents help users achieve their goals, whether that is resolving a technical issue, following a procedure, or understanding a technology.

The other options involve considerations that are not the primary focus of technical writing. The writer's feelings or emotional expression are not relevant in a technical context, nor is marketing, which focuses more on promotion than on conveying objective, factual information. Therefore, emphasizing the subject allows technical documents to serve their intended purpose effectively.
