A researcher discovered that people who have low levels of immune-system
activity tend to score much lower on tests of mental health than do people
with normal or high immune-system activity. The researcher concluded from
this experiment that the immune system protects against mental illness as well
as against physical disease.
The researcher's conclusion depends on which of the following assumption?
(A)High immune-system activity protects against mental illness better than
normal immune-system activity does.
(B)Mental illness is similar to physical disease in its effects on body systems.
(C)People with high immune-system activity cannot develop mental illness.
(D)Mental illness does not cause people's immune-system activity to decrease.
(E)Pyschological treatment of mental illness is not as effective as is medical
treatment.
答案是(D)
看OG的解釋覺得有點怪
感覺OG的答案不是在反對主題嗎?
我是把答案解讀成"心理疾病和免疫系統不會互相影響"
不知道是不是翻譯上有出入
麻煩各位大牛了~

: 剛看到推文的解釋,
: 但是還是不懂為何是這樣算啊?
: 可以講一下思路嗎?
: 謝謝喔~~
: : R,S,T是三個連續的整數,那麼3^R+3^S+3^T的和中最大的質因數是多少? 答案:13
: : V2   PS: x,y,z all >10, which is the largest prime factor of 3^x+3^y+3^z
: :    A 2
: :    B 3
: :    C 18
: :    D 19
: :    E 22
: : 13是怎麼算出來的呢？
: : 謝謝
x,y,z>10
thus assume (x,y,z)=(11,12,13)
3^11+3^12+3^13=3^11(1+3+9)=(x^11)(13)
最大質因數13
(舉其他的例子也通喔~)

Essay #9.  148  (22549-!-item-!-188;#058&00148-00)
In a new book about the antiparty feeling of the early political leaders of
the United States, Ralph Ketcham argues that the first six Presidents differed
decisively from later Presidents because the first six held values inherited
from the classical humanist tradition of eighteenth-century England. In this
view, government was designed not to satisfy the private desires of the people
but to make them better citizens; this tradition stressed the disinterested
devotion of political leaders to the public good.  Justice, wisdom, and
courage were more important qualities in a leader than the ability to organize
voters and win elections.  Indeed, leaders were supposed to be called to
office rather than to run for office.  And if they took up the burdens of
public office with a sense of duty, leaders also believed that such offices
were naturally their due because of their social preeminence or their
contributions to the country.  Given this classical conception of leadership,
it is not surprising that the first six Presidents condemned political parties.
Parties were partial by definition, self-interested, and therefore serving
something other than the transcendent public good.
Even during the first presidency (Washington's), however, the classical
conception of virtuous leadership was being undermined by commercial forces
that had been gathering since at least the beginning of the eighteenth century.
Commerce--its profit-making, its self-interestedness, its individualism--became
the enemy of these classical ideals.  Although Ketcham does not picture
the struggle in quite this way, he does rightly see Jackson's tenure (the
                                                    ^^^^^^^^^^^^^^^^
seventh presidency) as the culmination of the acceptance of party, commerce,
and individualism.  For the Jacksonians, nonpartisanship lost its relevance,
and under the direction of Van Buren, party gained a new legitimacy.  The
classical ideals of the first six Presidents became identified with a privileged
aristocracy, an aristocracy that had to be overcome in order to allow competition
between opposing political interests.  Ketcham is so strongly committed to
justifying the classical ideals, however, that he underestimates the advantages
of their decline.  For example, the classical conception of leadership was
incompatible with our modern notion of the freedoms of speech and press,
freedoms intimately associated with the legitimacy of opposing political
parties.
Question #32.  148-04   (22733-!-item-!-188;#058&000148-04)
Which of the following, if true, provides the LEAST support for the author's
argument about commerce and political parties during Jackson's presidency?
(A) Many supporters of Jackson resisted the commercialization that could
    result from participation in a national economy.
(B) Protest against the corrupt and partisan nature of political parties in the
    United States subsided during Jackson's presidency.
(C) During Jackson's presidency the use of money became more common than
    bartering of goods and services.
(D) More northerners than southerners supported Jackson because southerners
    were opposed to the development of a commercial economy.
(E) Andrew Jackson did not feel as strongly committed to the classical
    ideals of leadership as George Washington had felt.

In California, a lack of genetic variation in the Argentine ant has allowed
the species to spread widely; due to their being so genetically similar to
one another, the ants consider all their fellows to be a close relative and
thus do not engage in the kind of fierce intercolony struggles that limits
the spread of this species in its native Argentina.
A.      due to their being so genetically similar to one another, the ants
consider all their fellows to be a close relative and thus do not engage in
the kind of fierce intercolony struggles that limits
B.      due to its being so genetically similar the ant considers all its fellows
to be a close relative and thus does not engage in the kind of fierce
intercolony struggles that limit
C.      because it is so genetically similar, the ant considers all its fellows to
be close relatives and thus does not engage in the kind of fierce intercolony
struggles that limits
D.      because they are so genetically similar to one another, the ants consider
all their fellows to be close relatives and thus do not engage in the kind of
fierce intercolony struggles that limit
E.      because of being so genetically similar to one another, the ants consider
all their fellows to be a close relative and thus do not engage in the kind
of fierce intercolony struggles that limits
這題答案給C
但我覺得its是指代species 和c選項的because it is 裡面的 it 指代不同物件
所以我選了D
請問D的錯誤在哪邊阿?

United States hospitals have traditionally relied primarily on revenues from
paying patients to offset losses from unreimbursed care. Almost all paying
patients now rely on governmental or private health insurance to pay hospital
bills. Recently, insurers have been strictly limiting what they pay hospitals
for the care of insured patients to amounts at or below actual costs.
Which of the following conclusions is best supported by the information above?
(A) Although the advance of technology has made expensive medical procedures
available to the wealthy, such procedures are out of the reach of low-income
patients.
(B) If hospitals do not find ways to raising additional income for
unreimbursed care, they must either deny some of that care of suffer losses
if they give it.
(C) Some patients have incomes too high for eligibility for governmental
health insurance but are unable to afford private insurance for hospital care.
(D) If the hospitals reduce their costs in providing care, insurance
companies will maintain the current level of reimbursement, thereby providing
more funds for unreimbursed care.
(E) Even though philanthropic donations have traditionally provided some
support for the hospitals, such donations are at present declining.
這題答案是B, 但是我連題目都看不懂, 什麼是offset losses from unreimbursed care
可以請各位指點一下嗎...謝謝
