(See the complete passage discussion here: lsat/viewtopic.php?t=14300)
The correct answer choice is (B)
Based on the discussion of passage Differences above, we can create a general prephrase to answer
this Author Disagreement question: The main difference between the two authors is that while the
first regards fingerprint identification as a reliable form of evidence, the author of passage B views
it as imperfect and error-prone. Make sure to apply the Agree/Disagree test to any contenders: the
correct answer choice must contain a statement with which one of the two authors would agree,
while the other would disagree.
Answer choice (A): Uniformity in the training of fingerprint examiners is an issue that is not
referenced by either author, so this cannot be the correct answer to an Author Disagreement question.
Additionally, there is no reason to infer that there would be any disagreement on the question of
whether uniformity in examiners’ training is a desirable goal.
Answer choice (B): This is the correct answer choice. The judge in passage A accepts the
testimony at the defendant’s trial showing that fingerprint identification has an exceedingly low error
rate (lines 33-35), and sees no reason to reject it as a form of evidence (lines 21-23). By contrast,
the author of passage B implies that the rate of erroneous identification can be as high as 34 percent
(lines 63-65). Clearly, the two authors disagree about the likelihood that an examiner will incorrectly
declare a match.
Answer choice (C): Since the author of passage B questions the reliability of fingerprint
identification, she would most likely disagree with the bold claim that this practice be accorded the
status of scientific law. The judge in passage A, however, is unlikely to agree with it. Although the
first author views fingerprint identification as reliable, she also acknowledges that this practice has
not attained the status of scientific law (lines 16-17), conceding the need for further testing and more
consistent standards (lines 19-21). Because this answer choice does not pass the Agree/Disagree
Test, it is incorrect.
Answer choice (D): Only the author of passage B debates the relative merits of the point-counting
and holistic methods of fingerprint identification. We cannot assess the attitude of the first author
regarding either of these methods.
Answer choice (E): While the author of passage A would agree with this statement (lines 24-26), the
second author makes no reference to the degrees of correlation required by different agencies.
