几道让我看不懂的题,请热心人帮助!

13. Carl's Coffee Emporium stocks only two decaffeinated coffees: French Roast and Mocha Java Yusef only serves decaffeinated coffee and the coffee he served after dinner last night was smooth and mellow have been French Roast So if Yusef still gets all his coffee from Carl's what he served last night was Mocha Java.
The argument above is most similar in its logical structure to which one of the following?
(A) Samuel wants to take three friends to the beach His mother owns both a sedan and a convertible The convertible holds four people so although the sedan has a more powerful engine, if Samuel borrows a vehicle from his mother he will borrow the convertible
(B) If Anna wants to walk from her house to the office where she works she must either go through the park or take the overpass across the railroad tracks The park paths are muddy and Anna does not like using the overpass so the never walks to work
(C) Rose can either take a two-week vacation The trail she had planned to hike requires three weeks to complete but is closed by October so if Rose takes a vacation it will not be the one she had planned
(D) Werdix, Inc. has offered Arno a choice between a job in sales and a job in research Arno would like to work at Werdix but he would never take a job in sales when another job is available so if he accepts on of these jobs it will be the one in research
(E) If Teresa does not fire her assistant her staff will rebel and her department's efficiency will decline Losing her assistant would also reduce its efficiency so if no alternative solution can be found Theresa's department will become less efficient
D.这道题看得我云里雾里的,我连文章逻辑关系都看不明白,谁能帮帮忙?

Questions 14-15
Politician: The mandatory jail sentences that became law two years ago for certain crimes have enhanced the integrity of our system of justice, for no longer are there two kinds of justice, the kind dispensed by lenient judges and the kind dispensed by severe ones. Public advocate: But with judges stripped of discretionary powers, there can be no leniency even where it would be appropriate. So juries now sometimes acquit a given defendant solely because the jurors feel that the mandatory sentence would be too harsh. Those juries, then, do not return an accurate verdict on the defendant's guilt. This is why it is imperative that the legislation instituting mandatory jail sentences be repealed.
14. The public advocate responds to the politician's argument by doing which one of the following?
(A) trying to show that the politician's conclusion merely paraphrases the politician's evidence
(B) claiming that the politician's evidence, properly analyzed, has no bearing on the conclusion the politician derives from it.
(C) arguing that leniency is not a trait of individuals but that, rather, it is a property of certain kinds of decisions.
(D) arguing that an analysis of the consequences of certain legislation undermines the politician's conclusion
(E) charging that the politician exaggerated the severity of a problem in order to justify a sweeping solution
15. Which one of the following principles, if valid, provides the politician with the strongest basis for countering the public advocate's argument?
(A) Juries should always consider whether the sum of the evidence leaves any reasonable doubt concerning the defendant's guilt, and in all cases in which it does, they should acquit the defendant
(B) A system of justice should clearly define what the specific actions are that judges are to perform within the system.
(C) A system of justice should not require any legal expertise on the part of the people selected to serve on juries.
(D) Changes in a system of justice in response to some undesirable feature of the system should be made as soon as possible once that feature has been recognized as undesirable.
(E) Changes in a system of justice that produce undesirable consequences should be reversed only if it is not feasible to ameliorate those undesirable consequences through further modification.
选D,E.我基本上没看懂,两道都做错了.

Questions 24-25
Statistician: Changes in the Sun's luminosity correlate exceedingly well with average land temperatures on Earth. Clearly-and contrary to accepted opinion among meteorologists-the Sun's luminosity essentially controls land temperatures on Earth. Meteorologist: I disagree. Any professional meteorologist will tell you that in a system as complicated as that giving rise to the climate, no significant aspect can be controlled by a single variable
24. The rejection by the meteorologist of the statistician's conclusion employs which one of the following techniques of argumentation?
(A) supporting a conclusion about a specific case by invoking a relevant generalization
(B) producint a single counterexample that establishes that a generalization is false as state
(C) reanalyzing a correlation as reflecting the multiple effects of a single cause
(D) rejecting a conclusion because it is a proposition that cannot be experimentally tested
(E) pointing out that potentially unfavorable evident has been systematically neglected
25. The reasoning in the meteorologist's counterargument questionable because that argument
(A) rejects a partial explanation, not because it is incorrect but only because it is not complete
(B) fails to distinguish phenomena that exist independently of a particular system from phenomena that exist only as part of the system.
(C) calls into question the existence of a correlation when the only real issue is that of how to interpret the correlation
(D) dismisses a hypothesis on the grounds that is fail to deal with any matters of scientific significant
(E) appeals to the authoritativeness of an opinion without evaluating the merit of a putative counterexample
选A,E。看不懂

1        Carle has F/R and M/J.   Y serves F/R, so if Y still buy sth from Carle, it should be M/J

             所以你再分析一下D,正确。

14        politician: jail sentence 是好的,因为提高了司法体系的公正性,从此再也没有用仁慈和严厉来支配的司法判决了。
Public Advocate: but(强转折),由于法官被剥夺了随意性,所以即使应当有仁慈的时候也没有了。
其实读到这里就可以解题了,很明显,他反驳了politician 关于jail sentence是好的这样的论断
15        要weaken public advocate: 这题的关键我觉的是抓住public advocate 的 中心,就是jail sentence 不好。 仔细看一下选项
A : 中心在jury, B:中心是system 的action C:中心是 legal expertise D: 中心是change should be made。E:只有当没有改进空间的时候,这种change才应该被反驳

24        S: Sun 的luminosity 和temperature of Earth 有关而不是 sun’s luminosity control the temperature of Earth.   M: 反对。气象权威说,没有什么和气候联系在一起的东西是能被一个变量所控制的。
( 我读了也有点懵,应该是说,两者不能建立relation,但是这不影响解题)
             我觉得显然CDE是可以排除的,对于B,很迷惑,它说举了反例,但事实上我们看到的是M 说出了一个M认为正确的理论。只能选A,但觉的便扭

请其他同学补充

25   应该是比较明显的诉诸权威。

about Q13.
I just cann’t understand the second sentence :” Yusef only serves decaffeinated coffee and the coffee he served after dinner last night was smooth and mellow have been French Roast So if Yusef still gets all his coffee from Carl's what he served last night was Mocha Java. “
Could you explain it in more details?

TOP

关键是这句“ Yusef only serves decaffeinated coffee “ 与第一句话建立了联系。
