[背景资料]

某建筑集团公司三公司通过公开投标中标南方某省会城市一五星级宾馆工程。为了抢进度，外装修阶段，施工单位未经批准擅自决定改变原施工组织设计中外装饰用吊篮的方案，改为搭设钢管扣件式双排脚手架。但未经认真设计，只拟出一份简单的搭设方案，要求立杆加密，单杆改双杆，对建筑物一二层的凹进部分未予考虑。施工中，架子下面三步未铺脚手板，16组里外立杆设了12根小横杆，仅用木方木板把支立杆处的坑凹处垫了垫．大多数只用单股铅丝将架子与建筑物拉结，搭好后没有组织有关部门验收。几天后一座刚刚搭起的高40m，长16m，自重38t的双排钢管脚手架突然塌落，12名工人随架子同时坠落，被压在倒塌的架子下面，其中5人死亡，7人负伤。

问题：

脚手架及其他地基基础需在哪些阶段进行验收及检查？

There is a great deal of geographical variation in the frequency of many surgical procedures—up to tenfold variation per hundred thousand between different areas in the numbers of hysterectomies, prostatectomies, and tonsillectomies. To support a conclusion that much of the variation is due to unnecessary surgical procedures, it would be most important to establish which of the following

A．A local board of review at each hospital examines the records of every operation to determine whether the surgical procedure was necessary.

B．The variation is unrelated to factors (other than the surgical procedures themselves) that influence the incidence of diseases for which surgery might be considered.

C．There are several categories of surgical procedure (other than hysterectomies, prostatectomies, and tonsillectomies) that are often performed unnecessarily.

D．For certain surgical procedures, it is difficult to determine after the operation whether the procedures were necessary or whether alternative treatment would have succeeded.

E．(E) With respect to how often they are performed unnecessarily, hysterectomies, prostatectomies, and tonsillectomies are representative of surgical procedures in general.
