What aspect of writing is assessed when evaluating coherence and cohesion?

When evaluating coherence and cohesion in writing, the focus is primarily on the logical flow of ideas. Coherence refers to how well the ideas in a written piece connect and support a central theme, ensuring that readers can easily understand the writer's message. This involves a clear progression of thought, where one idea leads naturally to the next. Cohesion deals with the grammatical and lexical linking within a text, which helps to facilitate a seamless reading experience.

While the use of transition words plays a role in establishing that flow between sentences and paragraphs, coherence itself encompasses a broader understanding of how ideas are organized and presented. Thus, assessing coherence and cohesion ultimately revolves around the logical arrangement and connection of ideas, making the logical flow of ideas the crucial aspect being evaluated.
