Having read a story once, certain amnesia victims will read it faster the second time even though they can't recall having seen the story before. They have most likely suffered damage to the:.
a) amygdala.
b) hypothalamus.
c) hippocampus.
d) cerebellum.

option (C). hippocampus.

Explanation: hippocampus is an important part of the limbic system, a cortical region that regulates motivation, emotion, learning, and memory and it is a brain structure embedded deep in the temporal lobe of each cerebral cortex.

The hippocampus is part of the limbic system, and it plays a pertinent roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation, however, a person can experience a loss of memory and a loss of the ability to make new, long-term memories if the hippocampus is damaged.

answer; i believe the correct answer is (8) eight.

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)
