} | 正确答案是 B。galaxies 前后的两部分分别以 telescope can detect 和 it also records 为核心，都是可以独立成句的分句，因此应使用分号连接。A 保留逗号，会造成逗号拼接；C 的冒号通常用于引出解释、结果或具体内容，本句并非这种关系；D 删除标点会形成无标点连接的句子边界错误。 | [

"supporting_reason": "选项B使用单数谓语 reveals，与复杂主语中的中心词 collection 一致，准确解决了介词短语造成的主谓一致干扰。"
} | 正确答案是 B reveals。完整主语是 The collection of field notes from several coastal surveys，其中中心词是单数名词 collection，of field notes from several coastal surveys 只是修饰该中心词的介词短语。因此谓语必须使用单数形式 reveals。A reveal 与复数名词 surveys 的表面形式一致，但没有与真正的主语中心词保持一致；C have revealed 和 D are revealing 同样使用了复数形式，均不符合主谓一致要求。 | [

} | 正确答案是 B However。第一句说明社区花园起初是一块空地，第二句说明志愿者现在能够种植足够供应社区食物储藏室的蔬菜，前后状态构成明显对比。A Similarly 表示相似，不能表达这种反差；C For example 用于引出例子，句中没有例证关系；D Therefore 表示因果结果，但第二句重点不是第一句导致的结果，而是对花园现状的转折性补充。 | [
