The use of fingerprint analysis to identify criminal suspects dates back to the late 1800s, although the theory behind the technique existed long before it was actually used in practice.
In fact, the hypothetical possibility was so intriguing to Mark Twain that he used fingerprint identification as a plot device in his quasi-memoir Life on the Mississippi nearly a decade before fingerprints were used to solve a crime in real life. Since then, fingerprint analysis has become a standard law enforcement technique for real and fictional detectives alike. Yet, despite its widespread use, the practice has never been subjected to rigorous scientific study, and some of the assumptions that underpin its use—such as the notion that each person has a unique set of fingerprints—may not be accurate.
The time has come for the legal community to acknowledge that fingerprint analysis is an unsubstantiated forensic science and to advocate for more research in the field.In the argument given, the two portions in boldface play which of the following roles?
(A) The first is a detail that supports the author’s main idea, and the second raises a contrary opinion.
(B) The first is a detail that supports one opinion, and the second is a contrary opinion held by the author.
(C) The first introduces an opinion, and the second contradicts that opinion.
(D) The first is a detail that supports the author’s main idea, and the second is additional evidence for the author’s main idea.
(E) The first is a detail that supports a claim made in the argument, and the second is the author’s main point.
KAPLAN OFFICIAL EXPLANATION:
STEP 1: IDENTIFY THE QUESTION TYPEBecause the question stem asks you to identify the roles of statements in boldface, this is a Bolded Statement question.
STEP 2: UNTANGLE THE STIMULUSThe stimulus begins by providing some history about the use of fingerprint analysis and states that, over time, the technique has become a routine component of police investigations in real life and in popular culture. The key word “[y]et” signals an important shift: despite the widespread use of fingerprint analysis, it isn’t a well-studied science. From here, the author pivots to her recommendation that the legal community do more to encourage scientific research into the reliability of fingerprint analysis.
STEP 3: PREDICT THE ANSWERThe first bolded statement is part of the history of fingerprint analysis presented by the author. The author uses it as an example to support the claim made in the previous sentence that the theory of fingerprint identification predates its actual use. The second bolded statement is a recommendation made by the author. Because the other information presented in the stimulus build toward this recommendation, it is the author’s main point.
STEP 4: EVALUATE THE CHOICES(E) matches the prediction and is correct. (A) incorrectly states that the second statement is “contrary” to the author’s main idea, when in fact the opposite is true. (B) is incorrect because the first statement is supporting a factual claim, not an opinion, and the second statement is not a “contrary” opinion. Similarly, (C) claims that the first statement is an opinion, but it’s actually a supporting detail, and that the second statement “contradicts” the first, but there is no conflict between them. Finally, (D) is incorrect because it asserts that the second statement is evidence, but it is actually the author’s main point or conclusion.
