There are medical imaging software that can analyze MRI and CAT scan results to identify abnormal internal structures. However, these software work by comparing the degree of similarity between the image of the patient and an expected image rather than exact identity. After all, there is no exact internal structure. Software systems such as these can be modified to minimize false negatives, that is negative results in patients with an internal disease, but doing so may increase the likelihood of false positives, that is positive results in patients with no internal disease.
Which of the following conclusions is most strongly supported by the information above?
A. If these software were made to work by exact identification, they would not produce any incorrect results.
B. Doctors choosing a method to analyze MRI and CAT scans for abnormal structures should base the choice solely on the ratio of false positives to false negatives.
C. These software are only appropriate in situations in which a false positive in identifying an abnormal structure is less dangerous than failing to identify an abnormal structure is.
D. Manual analysis of MRI and CAT scans is less likely than software-based analysis to produce a false positive in identifying an abnormal structure.
E. If these software reliably prevent negative results in patients with an internal disease, they may sometimes produce false positive results.

false negative- there is disease but software shows negative
false positive- there is no disease but software shows positive
medical software - analyze MRI and CAT scan result to identify abnormal internal structures.
they compare the image of patient and expected image rather than exact identity.
this system can be modified to minimize false negative
result- but doing so would increase the likelihood of false positives. means it suggest to us that there is disease when there is not.
A. If these software were made to work by exact identification, they would not produce any incorrect results.
but passage says there is no exact internal structure. so this is not possible.
B. Doctors choosing a method to analyze MRI and CAT scans for abnormal structures should base the choice solely on the ratio of false positives to false negatives.
this has no impact whatsoever.
C. These software are only appropriate in situations in which a false positive in identifying an abnormal structure is less dangerous than failing to identify an abnormal structure is.
seriously? how that make sense. even less dangerous is bad so this doesnt strengthen much.
D. Manual analysis of MRI and CAT scans is less likely than software-based analysis to produce a false positive in identifying an abnormal structure.
then why did you build software? out.
E. If these software reliably prevent negative results in patients with an internal disease, they may sometimes produce false positive results.
this is what last line exactly tells. minimize false negatives - increase false positives. this choice says the same thing. software reliably prevent false negative - but sometime produce false positive.
