After Suzi's purse got stolen, the police asked her to look at mug shots to try to identify the perpetrator. After looking at several images, Suzi felt that they became blurred together in her mind—she no longer felt confident that she would be able to identify the man who stole her purse. In fact, she could no longer recall whether he had a moustache or not. The suggestibility of memory raises serious questions about using for courtroom evidence.

Eyewitness Testimony.

Explanation:

The term eyewitness testimony is a legal term that is used for the people who give an account of a certain event witnessed by them. This person can be the bystander or the victim himself. The account given by the eyewitness is usually descriptive. The person is required to describe the event in detail of how it started and what happened afterward. Eyewitness testimony includes crime details, perpetrator's identification, etc.

In the given context, the testimony of eyewitness is questionable because Suzi is not able to memorize the face of the perpetrator.

So, the correct answer is eyewitness testimony.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
