Correct Answer: part 13 when evaluating a piece of writing, particularly in tests or academic assessments, one common task is to identify parts of the text that diverge from the main idea or central theme. in this exercise, you are asked to determine which part of a selection does not contribute to developing its main idea. the correct answer repeatedly identified across multiple choices is "part 13."
here is a detailed explanation of why "part 13" is considered not to develop the main idea of the selection:
1. **relevance to main idea:** the main idea of a text is the central, unifying concept around which all other parts of the text are organized. each section, paragraph, or part of the text should ideally contribute something to this overarching theme or argument. if "part 13" is singled out consistently as the correct answer, it implies that this part of the text introduces ideas, examples, or information that do not align with or support the main concept. this could be because the content of part 13 is tangential, contradictory, or irrelevant to the primary focus of the text.
2. **content analysis:** without the specific content of part 13, one can only speculate about its nature based on the provided information. however, the repeated identification of this part as unrelated suggests that it might include a digression or an insertion of details that stray from the topic. for example, if the text were about the benefits of solar energy, and part 13 discussed unrelated historical events without tying them back to the topic, it would be seen as not developing the main idea.
3. **structural coherence:** effective writing should have structural coherence, meaning that all parts are logically connected and contribute to a clear, organized presentation of the main idea. if part 13 is unrelated, it disrupts this coherence, potentially confusing readers or diluting the impact of the main argument.
4. **editorial judgment:** the recommendation to remove part 13 from the text underscores its lack of contribution to the main idea. in editing and revising, removing non-contributory elements is crucial in strengthening the focus and clarity of the text. by eliminating unrelated content, the writer can ensure that the remaining parts more effectively communicate and reinforce the main idea.
5. **impact on reading and understanding:** an unrelated part like part 13 can impede the reader’s ability to follow the progression of thoughts or arguments laid out in the text. such interruptions can lead to misunderstandings or reduced engagement with the text, which is particularly detrimental in persuasive or informative writings.
in summary, part 13 of the selection does not develop the main idea because it introduces content that is extraneous to the central theme, disrupting the text's coherence and focus. in a well-crafted text, every component should serve a purpose in unfolding or supporting the main idea, and elements that do not fulfill this criterion are often better removed to enhance the clarity and effectiveness of the writing.
