Questions 31-35 refer to the following passage.
PASSAGE 3
       Much of the research of the past few decades has examined which therapies to use and how to use them. Which medication, what does, for how long? Which procedure? What's the benefit? These are all questions commonly asked and that can now be regularly and reliably answered.

       Treatment guidelines for many diseases are published, available, and regularly used. And despite concerns and lamentations about "cookbook medicine," these guidelines, based on a rapidly growing cornerstone of evidence have saved lives. These forms of evidence-based medicine allow patients to benefit from the thoughtful application of what's been shown to be the most effective therapy.

       But effective therapy depends on accurate diagnosis. We now have at our disposal a wide range of tools-new and old--with which we might now make a timely and accurate diagnosis. And as treatment becomes more standardized, the most complex and important decision making will take place at the level of the diagnosis.

       The patient's story and exam suggest a likely suspect and the technology of diagnosis rapidly confirms and hunch. An elderly man with a fever and a cough has an X-ray revealing a raging pneumonia. A man in his fifties has chest pain that radiates down his left arm and up to his jaw, and an EKG ( ＿＿＿ ) or blood test bears out the suspicion that he is having a heart attack. A teenage girl on the birth control pill comes in complaining of shortness of breath and a swollen leg, and a CT (Computed Tomography) scan proves the presence of a massive pulmonary embolus. This is the bread and butter of medical diagnosis－cases where cause and effect tie neatly together and the doctor can almost immediately explain to patient and family whodunit, how, and sometimes even why.

       But then there are the other cases: patients with complicated stories or medical histories; cases where the symptoms are less suggestive, the physical exam unrevealing, the tests misleading. Cases in which the narrative of disease strays off the expected path, where the usual suspects all seem to have alibis, and the diagnosis is elusive. For these, the doctor must don his/her deerstalker cap and unravel the mystery. It is in these instances where medicine can rise once again to the level of an art and the doctor-detective must pick apart the tangled strands of illness, understand which questions to ask, recognize the subtle physical findings, and identify which tests might lead, finally, to the right diagnosis.
