Vasquez-Morrell Assurance specializes in insuring manufacturers. Whenever a policyholder makes a claim, a claims adjuster determines the amount that Vasquez-Morrell is obligated to pay. Vasquez-Morrell is cutting its staff of claims adjusters by 15 percent. To ensure that the company’s ability to handle claims promptly is affected as little as possible by the staff cuts, consultants recommend that Vasquez-Morrell lay off those adjusters who now take longest, on average, to complete work on claims assigned to them. Which of the following, if true, most seriously calls into question the consultants’ criterion for selecting the staff to be laid off? (A) If the time that Vasquez-Morrell takes to settle claims increases significantly, it could lose business to other insurers. (B) Supervisors at Vasquez-Morrell tend to assign the most complex claims to the most capable adjusters. (C) At Vasquez-Morrell, no insurance payments are made until a claims adjuster has reached a final determination on the claim. (D) There are no positions at Vasquez-Morrell to which staff currently employed as claims adjusters could be reassigned. (E) The premiums that Vasquez-Morrell currently charges are no higher than those charged for similar coverage by competitors.

请问老师 画线部分这句话怎么没有谓语呢？我想了很久是省略了have been? 如果是这样的话，我发现省略的情况会影响我的阅读，可能是我对英文省略这块的语法不熟悉（什么时候可以省略，哪些可以省略等）老师能发我一些关于省略语法的资料我读读嘛，谢谢

从句不知道修饰谁的问题，有就近修饰的说法吗？怎么判断修饰谁呢：第一句 状语从句Where……打括号部分修饰museum还是Italy，说修饰Italy好像也翻译的通；第二句 that引导的从句 打括号部分修饰rationale还是social and political realities？在句中作什么成分呢; 第三句 that从句修饰evidence还是前面的Middle East？从句中的with和but怎么连在一起用呢

求问这个题，麻烦老师简明扼要解答一下 谢谢～
