Appendicitis(inflammation of the appendix) is potentially fatal; consequently, patientswith symptoms strongly suggesting appendicitis almost always have theirappendix removed. The appropriatesurgery is low-risk but performed unnecessarily in about 20 percent of allcases. A newly developed internal scanfor appendicitis is highly accurate, producing two misdiagnoses for every 98correct diagnoses. Clearly, using thistest, doctors can largely avoid unnecessary removals of the appendix without,however, performing any fewer necessary onesthan before, since ______. A. thepatients who are correctly diagnosed with this test as not having appendicitisinvariably have medical conditions that are much less serious than appendicitis B. themisdiagnoses produced by this test are always instances of attributingappendicitis to someone who does not, in fact, have it C. allof the patients who are diagnosed with this test as having appendicitis do, infact, have appendicitis D. everypatient who is diagnosed with this test as having appendicitis has more thanone of the symptoms generally associated with appendicitis E. theonly patients who are misdiagnosed using this test are patients who lack one ormore of the symptoms that are generally associated with appendicitis 妹纸你机经整理里是不是有这道题呢？阑尾炎误诊 貌似是GWD21-24的原题呢 望求证！
