【简答题】
某厂(甲方)与某公路工程公司(乙方)订立了厂区内道路施工合同，同时与某降水公司订立了工程降水合同。甲、乙双方合同规定：采用单价合同，每一分项工程的实际工程量增加(或减少)超过招标文件中工程量的10%以上时调整单价;工作B、E、G作业使用的主导施工机械一台(乙方自备)，台班费为400元/台班，其中台班折旧费为50元/台班。施工网络计划如图6-1所示。
甲、乙双方合同约定8月15日开工。工程施工中发生如下事件：
1.降水方案错误，致使工作D推迟2天，乙方人员配合用工5个工日，窝工6个工日。
2.8月21日至22日，场外停电，停工2天，造成人员窝工16个工日。
3.因设计变更，工作E工程量由招标文件中的300m3增至350m3，超过了10%;合同中该工作的综合单价为55元/m3，经协商调整后综合单价为50元/m3。
4.为保证施工质量，乙方在施工中将工作B原设计尺寸扩大，增加工程量15m3，该工作综合单价为78元/m3。
5.在工作D、E均完成后，甲方指令增加一项临时工作K，经核准，完成该工作需要i天时间，机械I台班，人工10个工日。
问题
(1).上述哪些事件乙方可以提出索赔要求?哪些事件不能提出索赔要求?说明其原因。
(2).每项事件工期索赔各是多少?总工期索赔多少天?
(3).工作E结算价应为多少?
