GMAT CLUB OLYMPICS: There are medical imaging software that can analyz

Explanation:

Mind-map: Medical imaging software analyze abnormal internal structures -> software compares degree of similarity between patients’ image and an expected image -> software does not perform exact identification of disease -> efforts to minimize false negatives may lead to increase in false positives

Missing-link: Not needed

Expectation from the correct answer choice: To be duly deducible from the information in the passage, without any assumption or extrapolation

A. It these software work by exact identification between the image of the patient and an expected image, it is likely that they rarely find an exact match, thus leading to a higher number of false positives or more incorrect results, contrary to what the answer choice mentions. Besides, the idea of no incorrect results is extremely strong; one needs to be cautious of such answer choices as they are generally incorrect on the GMAT. Because this answer choice does not indicate a conclusion of the argument, this answer choice is incorrect.

B. The argument mentions the software’s trade-off between false negatives and false positives but passes no judgment on how the ratio of the false positives and false negatives relates to the accuracy of the machines; so, this answer choice, suggesting that the ratio be a factor in the selection of machines, is out of scope. Additionally, “should be” indicates a suggesting/recommending/patronizing tone; one needs to be cautious of such answer choices as they are generally incorrect on the GMAT. Because this answer choice does not indicate a conclusion of the argument, this answer choice is incorrect.

C. Trap. The argument mentions the software’s trade-off between false negatives and false positives but passes no judgment on which kind of false signals is more dangerous; so, this answer choice, suggesting the appropriateness of the software in certain situations associated with false signals, is just a possibility, which, although relevant to the broad context of the argument, is not a conclusion of the argument. Because this answer choice does not indicate a conclusion of the argument, this answer choice is incorrect.

D. The argument makes no suggestion regarding or comparison with manual analysis; so, this answer choice, comparing manual analysis and software-based analysis, is just a possibility, which, although relevant to the broad context of the argument, is not a conclusion of the argument. Because this answer choice does not indicate a conclusion of the argument, this answer choice is incorrect.

E. Correct. The argument mentions that efforts to minimize false negatives may lead to an increase in false positives; in other words, if the software reliably prevents negative results in patients with an internal disease, the software may sometimes produce false positives, as the answer choice mentions. Because this answer choice indicates a conclusion of the argument, this answer choice is correct.

E is the best choice.
