The assessor is guided by a structured criteria set which determines how marks are apportioned and imputed. That said, the predominance of subjective judgment and the impression imparted from a particular choice in style of delivery carries substantial influence over the marking scheme which conventional templates may not necessarily be capable of accommodating. Give consideration to factors such as readership, the purpose of the document, and the context in which it will be assessed will help to decide the best writing style to use. Feature articles, although quite often constructed using a traditional essay framework, may also cover a broad and generic range of media categories.
Ultimately, it is onus upon the writer to decide as to the degree of relevancy of said, "bits and pieces". To what extent can these elements be incorporated into the body of the piece and to what effect? The specific prompt would probably implicate the nature of contextual factors pending discussion as well as provide semantic cues to enable the writer to select the most circumstantially appropriate format to stylise their response. As a general rule of thumb, if the article demonstrates structural integrity, propriety of form and seems analytically sound then that may be indicative of permissible style. Choice of style, and the salience of which, is all contingent upon the given prompt.
