Correct Option: D. at close range Explanation of the Correct Answer The phrase "at close quarters" means being in close proximity to someone or something, allowing for detailed observation or interaction. In this context, it suggests that the speaker has had the opportunity to observe the person closely, likely noticing details that would not be apparent from a distance. Why Option D is Correct: - Meaning Alignment: "At close range" is synonymous with "at close quarters." Both phrases imply being physically near to someone or something, which allows for a more intimate or detailed observation. This is the essence of the original phrase in the sentence. - Contextual Relevance: The context of observing someone closely fits perfectly with the idea of being at close range, as it suggests a direct and personal experience. Why the Other Options are Incorrect Option A: in government house nearby - Meaning Mismatch: This option suggests a specific location (a government house) that is nearby, which does not convey the idea of close observation. It implies a geographical context rather than the physical proximity needed for detailed observation. - Lack of Observation Context: The phrase does not relate to the act of observing someone closely; instead, it focuses on a location, which is irrelevant to the original meaning. Option B: within a short space of time - Temporal Focus: This option refers to a duration of time rather than physical proximity. "Within a short space of time" suggests that something happened quickly, but it does not relate to the idea of observing someone closely. - Observation Irrelevance: The original phrase is about the closeness of observation, not the timing of it. Therefore, this option does not capture the intended meaning. Option C: in a small family house - Location Specificity: This option again focuses on a specific type of location (a small family house) rather than the concept of proximity for observation. It does not convey the idea of being close enough to observe someone in detail. - Irrelevant Context: The phrase does not relate to the act of observing someone closely, making it an unsuitable choice.
