精练--20s--Weaken
Premise：Carl only solve 1 out of 25 cases in the past 3 years.
Conclusion: Carl is incompetent detective.
Prephrase: 1 out of 25 cases can be the most difficult case Carl has been dealing with.
Analysis:
(A) Because the police chief regards Carl as the
most capable detective, she assigns him only
the most difficult cases, ones that others have
failed to solve.
---------------------------------------------------------correct. this choice brings new info. to identify the specialty of the cases that Carl dealt with is different from other detectives'.

(B) Before he became a detective, Carl was a
neighborhood police officer and was highly
respected by the residents of the
neighborhood he patrolled.
--------------------------------------------------------what position Carl used to be is irrelevant with the cases he's currently dealing with.

(C) Detectives on the police force on which Carl
serves are provided with extensive resources,
including the use of a large computer
database, to help them solve crimes.
-----------------------------------------------------------If the external resources can provide better service to improve the efficiency of cases, then this is to support the argument that Carl is not a good detective.

(D) Carl was previously a detective in a police
department in another city, and in the 4 years
he spent there, he solved only 1 out of 30
crimes.
---------------------------------------------------------- this kinda restate the premise in the argument, this will not help to weaken the conclusion at all.

(E) Many of the officers in the police department in
which Carl serves were hired or promoted
within the last 5 years.
---------------------------------------------------------------Other officers' promotion changes are irrelevant with Carl, if there's anything, this choice supports the conclusion by inferring Carl is not promoted yet.


不知道这么分析行不行，准备精练题目就这么分析，然后下面的练习题目就稍微在选项的解释上活分一些。等待我们家版主纠正

精炼题：
Premise: he solved s smaller percentage of the cases.
Conclusion: carl is incompetent detective.
Conclusion: carl is incompetent detective.

Weaken:case难度大，都是疑难杂按。
逻辑思路：案件办理的少=/= 办案能力低，不胜任detective
第二题
Premise: laboratory made the fullerenes
Conclusion: geologists can evaluate the state of the Earth’s crust.
Weaken: 满足制造fullerens的条件不能预测Earth’s crust，还会有其他条件。即：多种条件导致Earth’s crust

第一次回逻辑贴，是这样分析吗？而且没有选项啊。谁能告诉我。谢谢

嘻嘻~还是要回去看一下，毕竟和之前的逻辑链不一样，还是细致点好！

这一楼来弄剩下的逻辑~2-----42s----weaken
P: Only distinctive environment and temp. can make the fullnenes formed in lab.
C: The hypothesis of state of earth's crust should be evaluated while the fullnenes are formed.
Prephrase: The fullnenes are formed by themselves in non-distinctive environment.


(A) Confirming that the shungite genuinely contained fullerenes took careful experimentation.
--this is to support the conclusion.
(B) Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft.
--we are talking about the formation of F. under particular environment,  yet not the findings of F on the meteorite, this is irrelevant.
(C) The mineral shungite itself contains large amounts of carbon, from which the fullerenes apparently formed.
--the content of mineral S. itself doesn't mention anything about living environment of F.
(D) The naturally occurring fullerenes are arranged in a previously unknown crystalline structure.
--bingo!
(E) Shungite itself is formed only under distinctive conditions.
--support



3---20s-----weaken
P: The emergency treatment for elder people who fall cost $11,000.
P: However, the new program can help people to prevent falling, but it cost $12,5000.
C: Therefore, the new program cannot be justified.
Prephrase：More people will not only pay the emergency treatment, but also pay for the post-treatment fees if not implement the new program.

(A) Among elderly people who had followed the program for only a few months, the number of serious falls reported was higher than it was for people who had followed the program for its recommended minimum length of one year.
-- support the conclusion.
(B) Falls resulting in serious injuries are less common among elderly people living in nursing homes than they are among elderly people who live alone at home.
--nowhere has mentioned nursing homes, this is an irrelevant comparison.
(C) A frequent result of injuries sustained in falls is long-term pain, medication for which is not counted among the average per-person costs of emergency treatment for elderly people's injuries from such falls.
-- bingo!
(D) The new therapeutic program focuses on therapies other than medication, since overmedication can cause disorientation and hence increase the likelihood that an elderly person will have a serious fall.
-- how the new program cure people is out of scope.
(E) A significant portion of the cost of the new therapeutic program is represented by regular visits by health care professionals, the costs of which tend to increase more rapidly than do those of other elements of the program.
--regular visits of health care professional is irrelevant, and also this is to support the conclusion.


有点事情先走，晚点再来补后面的~~
