may help to resolve an
apparent contradiction
(E) describe a hypothesis that has cause a con-
troversy
18.It can be inferred from the passage that the author
would most likely describe the "additional evidence"
(line 12) provided by experiments with adrenergic
antagonists as
(A) revolutionary
(B) disappointing
(C) incomplete
(D) unexpected
(E) corroborative
19.The passage provides information about which of the
following topics?
(A) The mechanism by which glucose affects memory
storage
(B) The evidence that prompted scientist to test the
effects of adrenaline on memory regulation
(C) The reason that the effects of glucose on memory
were tested
(D) The ways that memory storage modifies the struc-
ture of the brain
(E) The kinds of training used to test memory enhance-
ment in rats
20.The author refers to the results of the experiment using
adrenergic antagonists as "negative findings" (line 13)
most likely because the adrenergic antagonists
(A) failed to disrupt adrenaline’s effect on memory
(B) did not affect glucose’s ability to enhance memory.
(C) did not block adrenaline’s ability to increase blood
glucose levels
(D) only partially affected adrenaline’s ability to
enhance memory
(E) disrupted both adrenaline’s and glucose’s effect
on memory
The age at which young children begin to make moral
discriminations about harmful actions committed against
themselves or others has been the focus of recent research
into the moral development of children. Until recently,
(5)child psychologists supported pioneer developmentalist Jean.
Piaget in his hypothesis that because of their immaturity,
children under age seven do not take into account the inten-
tions of a person committing accidental or deliberate harm,
but rather simply assign punishment for transgressions on
(10)the basis of the magnitude of the negative consequences
caused. According to Piaget, children under age seven
occupy the first stage of moral development, which is char-
acterized by moral absolutism (rules made by authorities
must be obeyed) and imminent justice (if rules are broken,
(15)punishment will be meted out). Until young children mature,
their moral judgments are based entirely on the effect
rather than the cause of a transgression. However, in recent
research, Keasey
