3系列最后一波~~吼吼~原来逻辑练习都3季了，呵呵，很有满足感~
前两天又没有练习了。我要从今天开始坚持每天做作业。


41. Dental researchers recently discovered that toothbrushes can become contaminated with bacteria that cause
pneumonia and strep throat. They found that contamination usually occurs after toothbrushes have been used
for four weeks. For that reason, people should replace their toothbrushes at least once a month.
Which of the following, if true, would most weaken the conclusion above?
(A) The dental researchers could not discover why toothbrush contamination usually occurred onlyafter
toothbrushes had been used for four weeks.
(B) The dental researchers failed to investigate contamination of toothbrushes by viruses, yeasts, and other
pathogenic microorganisms.
(C) The dental researchers found that among people who used toothbrushes contaminated with bacteria that
cause pneumonia and strep throat, the incidence of these diseases was no higher than among people who
used uncontaminated toothbrushes.
(D) The dental researchers found that people who rinsed their toothbrushes thoroughly in hotwater after each
use were as likely to have contaminated toothbrushes as were peoplewho only rinsed their toothbrushes
hurriedly in cold water after each use.
(E) The dental researchers found that, after six weeks of use, greater length of use of a toothbrush did not
correlate with a higher number of bacteria being present.


42. Leaders of a miners' union on strike against Coalco are contemplating additional measures to pressure the
company to accept the union's contract proposal. The union leaders are considering as their principal new tactic
a consumer boycott against Gasco gas stations, which are owned by Energy Incorporated, the same
corporation that owns Coalco.
The answer to which of the following questions is LEAST directly relevant to the union leaders' consideration of
whether attempting a boycott of Gasco will lead to acceptance of their contract proposal?
(A) Would revenue losses by Gasco seriously affect Energy Incorporated?
(B) Can current Gasco customers easily obtain gasoline elsewhere?
(C) Have other miners' unions won contracts similar to the one proposed by this union?
(D) Have other unions that have employed a similar tactic achieved their goals with it?
(E) Do other corporations that own coal companies also own gas stations?




43.Laws requiring the use of headlights during daylight hours can prevent automobile collisions. However, since
daylight visibility is worse in countries farther from the equator, any such laws would obviously be more effective
in preventing collisions in those countries. In fact, the only countries that actually have such laws are farther
from the equator than is the continental United States.
Which of the following conclusions could be most properly drawn from the information given above?
(A) Drivers in the continental United States who used their headlights during the day would bejust as likely to
become involved in a collision aswould drivers who did not use their headlights.
(B) In many countries that arefarther from the equator than is the continental United States, poor daylight
visibility is the single most important factor in automobile collisions.
(C) The proportion of automobile collisions that occur in the daytime is greater in the continental United
States than in the countries that have daytime headlight laws.
(D) Fewer automobile collisions probably occur each yearin countries that have daytime headlight laws than
occurwithin the continental United States.
(E) Daytime headlight laws would probably do less to prevent automobile collisions in the continental United
States than theydo in the countries that have the laws.


44. Bank depositors in the United States are all financiallyprotected against bank failure because the government
insures all individuals' bank deposits. An economist argues that this insurance is partly responsible for the high
rate of bank failures, since it removes from depositors any financia l incentive to find out whether the bank that
holds their money is secure against failure. If depositors were more selective, then banks would needto be
secure in order to compete for depositors' money.
The economist's argument makes which of the following assumptions?
(A) Bank failures are caused when big borrowers default on loan repayments.
(B) A significant proportion of depositors maintain accounts at several differentbanks.
(C) The more a depositor has to deposit, the more careful heor she tends to be in selecting a bank.
(D) The difference in the interest rates paid to depositors by different banks is not a significant factor in bank
failures .
(E) Potential depositors are able to determine which banks are secure against failure.




AA就跟着10月JJ的顺序来啦~ 今天是JJ NO.4  这题重复了>.<
The following appeared as part of a business plan created by the management of the Take Heart Fitness Center:
“After opening the new swimming pool early last summer, Take Heart saw a 12 percent increase in the use of the center by its members. Therefore, in order to increase membership in Take Heart, we should continue to add new recreational facilities in subsequent years: for example, a multipurpose game room, a tennis court, and a miniature golf course. Being the only center in the area offering this range of activities would give us a competitive advantage in the health and recreation market.”


补上新的：
“A recent review of the West Cambria volunteer ambulance servicerevealed a longer average response time to accidents than was reported by acommercial ambulance squad located in East Cambria. In order to provide betterpatient care for accident victims and to raise revenue for our town bycollecting service fees for ambulance use, we should disband our volunteerservice and hire a commercial ambulance service.”

Laws requiring that automobile should turn on headlights in day time is more effective in the area that is farther from the equator.

Conclusion:
If the U.S. enacts such law, the automobile collision is less likely to be ameliarated.
E

4. 55s
Premise:

insurance is partly responsible for the high rate of bank failures
Because the customers are not sure about the security of the banks, and they may not receive guarantee.

Assumption:
The depositors are capable of discerning the good from the bad.

1.the report figures may not accurate, the reporter may manipulate the data.
2.there may be some reasons for the  volunteer ambulance long response time.
3.The measure that disband volunteer service and hire commercial service may have some disadvantages.

E

4. 60s+

第一题的D为什么可以strenghten???!!!!!太奇怪了！

我觉得D的意思，就是排除其他可以降低污染的方式，所以加强~~必须通过换牙刷来减少细菌的污染~

1.【32s】
P：toothbrush is likely to become contamination when used for four weeks and thus cause disease..
C: we should change the toothbrush every one month.
