Answer:
"D. Creating clear transitions" is NOT a prewriting strategy.
Explanation:
Creating clear transitions is not a prewriting strategy because it should be done once a text is written down, and not before. This technique aims to create fluency and coherency between the ideas, sentences and paragraphs in a text. Clear transitions are created with the help of appropriate Transitional Expressions, such as: however, also, moreover, to summarize.
By contrast, "C. Reading good models of writing" is an activity that could be done before starting to write, aiming to gain a perspective on how to design and structure ideas in a written form. Similarly, answers "A. Mapping/webbing/ clustering" and "B. Finding similarities and differences", are writing strategies (often named brainstorming techniques) that help an author identify the ideas she/he wishes to express before starting the actual writing process. Another useful prewriting strategy it listing ideas; this helps to narrow down a subject when it is still too broad.
