题目：
Which of the following most logically completes the passage?
Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed. The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases. A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses. Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.
选项:
A、the patients who are correctly diagnosed with this test as not having appendicitis invariably have medical conditions that are much less serious than appendicitis
B、the misdiagnoses produced by this test are always instances of attributing appendicitis to someone who does not, in fact, have it
C、all of the patients who are diagnosed with this test as having appendicitis do, in fact, have appendicitis
D、every patient who is diagnosed with this test as having appendicitis has more than one of the symptoms generally associated with appendicitis
E、the only patients who are misdiagnosed using this test are patients who lack one or more of the symptoms that are generally associated with appendicitis
答案:
B
提问：
请陆旭老师回答一下。我选了C。因为我对C的理解是test不会将没有阑尾炎的人误诊成了有阑尾炎的人，换句话说就是误诊都是把有阑尾炎的人误诊成了没有阑尾炎的人。这样，医生至少是避免了不必要的阑尾手术的。而B和C的意思相反，说的是test的误诊通常是将没有阑尾炎的人误诊成了有阑尾炎的人。这样的话医生还是无法避免一些不必要的手术，没办法构成一个原因。请老师解答一下，感谢！

提问：
这道题逻辑链在做题时没有特别能体会出来选项要打的位置。我读的信息是：有阑尾炎症状的病人基本上都会被摘除阑尾，这种手术低风险但有好多手术没必要做。一项新的技术可以提高诊断的精确度从而降低误诊率，医生也就可以减少不必要的手术量了。因为---- A说的新技术确诊无阑尾炎的病人的医疗条件不如那些确诊有阑尾炎的。这个扯太远。杀。B 这项技术误诊情况经常是把有阑尾炎的说成没有阑尾炎---所以。不是阑尾炎的假象可以减少医生做多余的手术。就上原文 我所以这就类似于宁可少确诊一例，也不可误诊阑尾炎数量畸高。C 说所有确诊有阑尾炎的都是真实患有阑尾炎的。这个选项本来想选的，是不是也没说误诊率低的事情，所以这项没有贡献 是吗？
