Final answer:
The transition in topic from fish in clear streams to those in muddy streams is indicated by keywords or phrases that signal a change in the environment, such as 'the current slows', 'more sedimentation', and 'the water is also warmer'. These transitional words or phrases are essential for maintaining the flow and structure of the narrative.
Step-by-step explanation:
The question asks about the shift in the subcategory of fish from those caught in clear streams to those in muddy streams within a text. In analyzing text, authors may utilize various transitional strategies to guide readers from one subject or idea to another. These transitions are crucial for maintaining smooth narrative flow and for making complex information more digestible. In the provided references, the author signals a shift in topic with transitional words or adjustments in theme. For instance, words like "Meanwhile," "Also," and "However" are often used to indicate topic transitions. These words serve as signpost to readers that the topic is changing.
In the context of the referenced paragraphs, the transition likely occurs at the start of a new paragraph or where there's a notable change in subject matter, discussed elements, or environment attributes. The author may shift from discussing fish in clear streams to those in muddy streams by describing the change in the water's clarity, sedimentation, and the associated adaptations of aquatic life. Phrases that describe the river or stream's changing conditions, like 'the current slows,' 'more sedimentation,' and 'the water is also warmer,' could be key indicators of such a transition between subcategories.
Students are instructed to look for these cues in their texts to identify where authors navigate between different ideas or sections. Additionally, in analyzing text, students should note how effective these transitions are in providing clarity and aiding understanding of the text's structure.
