Choose the most logical order of sentences from among the four given choices to construct a coherent paragraph. 
A. A sentence, or a short passage, has to be enlarged into a paragraph by the fuller and more elaborate expression of the meaning. 
B. In précis-writing we have to compress; and in this exercise we have to expand. 
C. This exercise is the exact opposite of précis-writing. 
D. Such an exercise practically amounts to the writing of a miniature original sentence or passage. 

To determine the most logical order of sentences to form a coherent paragraph, let's analyze the relationship and progression of ideas in each sentence: ·        Sentence C introduces the topic by stating that "This exercise is the exact opposite of précis-writing." This serves as a strong introductory statement because it sets the context for what follows. ·        Sentence B elaborates on the introductory idea, explaining the differences between the exercise described and précis-writing: "In précis-writing we have to compress; and in this exercise we have to expand." ·        Sentence A details what the exercise involves: "A sentence, or a short passage, has to be enlarged into a paragraph by the fuller and more elaborate expression of the meaning." ·       Sentence D concludes by describing the outcome or the nature of the exercise: "Such an exercise practically amounts to the writing of a miniature original sentence or passage." The logical sequence that adheres to this progression is C (introduction of concept), B (elaboration of the contrast), A (description of the exercise), D (description of the result) . Therefore, the correct answer would be:
