The correct option for completing the sentence "This writer analyses the evil society ...." is D. in a masterly way. Explanation of the Correct Answer

1. Understanding the Phrase: The phrase "in a masterly way" is an idiomatic expression that means to do something with great skill or expertise. In this context, it describes how the writer conducts their analysis of the evil society.
2. Grammatical Structure:
3. The phrase "in a masterly way" follows a common English structure where "in a [adjective] way" is used to describe the manner in which an action is performed.
4. Here, "masterly" is an adjective that describes the quality of the analysis, and "way" indicates the manner of the action (the analysis).
5. Clarity and Precision: This option is clear and precise. It effectively communicates that the writer's analysis is not just good, but done with a high level of skill.

Why the Other Options Are Incorrect or Weaker

• Option A: so masterly
• Explanation: The phrase "so masterly" is incomplete in this context. It suggests a degree of mastery but lacks a structure to indicate how the analysis is performed. It would require additional context or a follow-up clause (e.g., "so masterly that it captivates the reader") to make sense.
• Option B: very masterly
• Explanation: While "very masterly" does convey a sense of high skill, it is less formal and less idiomatic than "in a masterly way." It also lacks the descriptive structure that clearly indicates the manner of the analysis. In formal writing, "very" is often seen as weaker than more descriptive phrases.
• Option C: in such a masterly way
• Explanation: This option is grammatically correct but is unnecessarily wordy. The phrase "such a" implies a comparison or a specific context that is not provided in the sentence. It could be used if there was a prior mention of what kind of masterly analysis is being referred to, but in isolation, it feels incomplete.
