(他对会议作了简明扼要的报道。) clear 清楚的。precise (=exact; correctly stated; free form error) 精确的, 明白无误的; Please tell me the precise measurements. (请告诉我精确的尺寸。) elaborate (=worked out with much care; carefully prepared) 精心制作的, 丰盛的：Peter worked out an elaborate scheme for raising the money. (彼得制定了一项详尽得计划来筹集着笔款项。) 孤立地看, 似乎4 个形容词均能修饰report, 但从句子的逻辑关系看, 后半句中有only in a few pages but with all the details, 故concise 是最贴切的选择了。
