句子图只保留主干、修饰和连接关系；证据链只保留从题干约束到原文依据再到选项判断的必要步骤。
先锁定限定谓语，再把从句和修饰语挂回它们真正说明的对象。
The records that the research team collected during the pilot, though incomplete, have suggested that the change is worth testing further.
主句是 The records have suggested that...。that the research team collected during the pilot 修饰 records；though incomplete 是让步性省略结构；第二个 that 引导 suggested 的宾语从句。
The lab repeated the field trials, which had been delayed by a shortage of sensors, after new equipment arrived.
which 紧接复数名词 field trials，且“试验被推迟”语义成立；after 从句修饰 repeated，说明再次试验的时间。
把定位、同义改写、推理许可和干扰项排除放在同一条链上核对。
Recorded visits rose by 18 percent, while the number of borrowed books changed little. Staff cautioned that the pilot overlapped with a university examination period, which may have temporarily increased demand.
Which statement best describes the result of the initial pilot?
任务是概括初步结果，答案必须覆盖测量结果并保留不确定性。
下一步：定位范围题干要求概括结果。原文证据是访问量上升、借阅量变化小，并提醒考试期可能影响需求。因此只能说试点与这些变化同时出现，不能断言延长开放永久造成增长。
The city extended the pilot for six months and planned to compare the branches with a similar branch that retained its old hours.
What can reasonably be inferred about the city's view of the initial evidence?
推断对象是城市对初步证据的判断，而不是政策最终效果。
下一步：原文证据、原文证据城市延长试点说明它认为初步信号值得继续研究；同时设置对照说明证据尚不充分。两项行动共同支持“有希望但未定论”，不支持立即全面推广。
