Question 23

To establish the subject

A topic sentence primarily serves to establish the subject of a paragraph, providing a clear focus and direction for the reader. It lays the groundwork for the details and arguments that will follow, ensuring coherence and relevance throughout the paragraph.

A) To call to action

This option is incorrect because a call to action is typically used in persuasive writing to prompt the reader to take specific steps or actions. While important in certain contexts, it does not represent the fundamental role of a topic sentence in establishing the main idea of a paragraph.

B) To analyze details

While analyzing details is an important aspect of paragraph development, it is not the primary purpose of a topic sentence. The topic sentence serves to introduce the main idea, while the analysis and details are elaborated upon in the subsequent sentences.

C) To raise a concern

Raising a concern may be relevant in specific contexts, particularly in argumentative writing. However, this is not the primary function of a topic sentence, which is focused on establishing the central subject rather than presenting a problem or concern.

D) To establish the subject

This option is correct as the primary purpose of a topic sentence is to establish the subject of the paragraph. It succinctly conveys the main idea that the writer intends to discuss, thereby guiding the reader's understanding of the content that follows.

Conclusion

In conclusion, the primary function of a topic sentence is to establish the subject, allowing for a clear and structured approach to writing. Options A, B, and C do not fulfill this fundamental role, as they focus on actions or analyses that occur after the topic has been introduced. Thus, D is the only choice that accurately captures the essential purpose of a topic sentence.
