Which TWO of the following quotes from the text best summarize the benefits of Rob Rowe's
fingerprint scanner?
A. "When investigating a crime, police often look for fingerprints... Later, if a fingerprint lifted from
the scene of a crime matches one on file, police know that person was at the scene." (Paragraph
31)
B. "It can be hard to get a good print from people who have worn down the skin on their fingers... It
also can be hard to get good fingerprints from young children" (Paragraph 32)
C. "An optical physicist, Rowe studies light and how it interacts with things." (Paragraph 33)
D. "When someone places a finger on the pad, different colors of light illuminate it from below."
(Paragraph 34)
E. "As each wavelength of light bounces back to the scanner, it creates a pattern tracing out the
blood vessels within the finger" (Paragraph 36)
F. "It turns out blood vessels and other structures below the skin have the same shape as the
fingerprint on the surface of the finger'... So an image of those vessels is just as good as a
fingerprint, if not better." (Paragraph 37)
