1. Downtown Villieu was once a flourishingbusiness district, but most Villieu-area businesses are now located only in thesuburbs.  The office buildings downtownlack the modern amenities most business operators demand today.  To lure more businesses downtown, Villieuofficials plan to have several modern office buildings constructed and to offerreduced local tax rates to any business that leases space in a new downtownbuilding

Which of the following, if true, most threatensthe plan's likelihood of success?

--PREP07 CR2 NO.2
Key:

The local tax rates in Villieu's suburbs aresignificantly lower than downtown Villieu's proposed rate for businesses thatlease space in the new office buildings.

2. United Lumberwill use trees from its forests for two products.  The tree trunks will be used for lumber andthe branches converted into wood chips to make fiberboard.  The cost of this conversion would be the samewhether done at the logging site, where the trees are debranched, or atUnited's factory.  However, wood chipsoccupy less than half the volume of the branches from which they are made.

The information given, if accurate, most stronglysupports which of the following?

--PREP07 CR2 NO.7

Key: Transportationcosts from the logging site to the factory that are determined by volume ofcargo would be lower if the conversion into chips is done at the logging siterather than at the factory.

3. Microscopicplants called algae grow inside the top layer of sea ice in the Antarctic ifenough sunlight reaches that layer of ice and enough seawater, which containsnutrients, reaches that layer after splashing onto the surface.  Even though moderate snow cover reduces thesunlight that filters into the top layer, sea ice with moderate snow covertypically contains even more algae in the top layer than does sea ice with lesssnow cover.

Which of the following, if true, most helps toexplain the apparent discrepancy?

--PREP07 CR2 NO.5

Key: As the weight of accumulated snow forces icelower in the water, more seawater splashes onto the surface and seeps throughthe snow.

4. Radio stationswith radio data system (RDS) technology broadcast special program informationthat only radios with an RDS feature can receive.  Between 1994 and 1996, the number of RDSradio stations in Verdland increased from 250 to 600.  However, since the number of RDS-equippedradios in Verdland was about the same in 1996 as in 1994, the number ofVerdlanders receiving the special program information probably did not increasesignificantly.

Which of the following is an assumption on whichthe argument depends?

-- PREP07 CR2NO.11

Key: Few if any ofthe RDS radio stations that began broadcasting in Verdland after 1994 broadcastto people with RDS-equipped radios living in areas not previously reached byRDS stations.

5. The followingappeared in a memorandum from a company’s marketing department:

“Since our company started manufacturing andmarketing a deluxe air filter six months ago, sales of our economy filter—andcompany profits have decreased significantly.

The deluxe air filter sells for50 percent more than the economy filter, but the economy filter lasts for onlyone month while the deluxe filter can be used for two months before it must bereplaced. To increase repeat sales of our economy filter and maximize profits,we should discontinue the deluxe air filter and concentrate all our advertisingefforts on the economy filter.”

Discuss how well reasoned . . . etc.

United Lumber will use trees from its forests for two products.  The tree trunks will be used for lumber and the branches converted into wood chips to make fiberboard.  The cost of this conversion would be the same whether done at the logging site, where the trees are de branched, or at United's factory.  However, wood chips occupy less than half the volume of the branches from which they are made.
The information given, if accurate, most strongly supports which of the following?
wood chips木屑 lumber木材
信息：树干和树枝有两种用途，不管在伐树的地方加工还是厂里加工成本都是一样的。但是chip的体积比树枝的一半还小

推论：在伐木的地方加工不好。
Key: Transportation costs from the logging site to the factory that are determined by volume of cargo would be lower if the conversion into chips is done at the logging site rather than at the factory.总结上文

Which of the following, if true, most helps toexplain the apparent discrepancy?
Splash溅 seep渗
前提：一种藻类生活在南极洲的冰下，需要阳光和营养水，所以一般生活上上层。雪的覆盖会减少阳光的射入。
结论：其实有雪的时候，上层的藻类反而很多。

解释：雪可以带来很多营养。
Key: As the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow.

Conclusion: The plan to lure business back to downtown would have its intend effect
Premise: The plan will give tax credits to business

Weaken: Still that tax cannot lure people back

2.  45s   脑袋有点呆滞。。
Info1: The trees have two function, one... the other...
Info2: The conversion fee are the same whether they are converted at log spot or at the factory
Info3：But the transportation fee is not..

Infer: Say sth. about the transportation, a comparison between two cites...

3. 40s
Info1: Algea grow well when there are lots of sunshine and nutritions
Info2: Ice can hamper sunshine from reaching the sea, but this area still has higher level of algea

Resolve: Ice can bring in more nutritions

4. 40s
Conclusion: The numer of people receive RDS program did not increase
Premise: Though station number increased, people with RDS equipment does not increase

Assumption: 想的和答案不一样，我在想：Tech does no improve that enable RDS station can broadcast its programs to those who do not have RDS receptors

不行不行，不能晚上做逻辑。。。脑袋根本不跟着转啊。1！！！……！……！……！

Premise: V was used to be a flourished office buildings area, but it  has been declined recently since most buildings move to suburban.
Conclusion: The new office buildings will be offered reduction of tax if they locate their office in new downtown building.
Weaken: The office building where they located now already enjoy the reduction of tax.

PRemise: the conversion of wood chips cost the same on the site and the factory.
Conclusion: However, the wood chips are converted is half less in volume than the branches.
Strengthen: The materials that can convert the wood chips are very selective. (答案又一步证明我理解错了)
答案是说由于conversion fee一样，但是transportation fee比较贵，所以从site运到factory的chip woods volume才比较少吗？
脑子处于短路中...............

49s
Premise: The sunlight help the algae grow well on the top layer of seawater.
Conclusion:  Seawater will have more algae on top layer if covered by more snow than covered by less snow.
Resolve: snow can store more oxidant and transfer it to the top layer.

44s
Premise: The equipped radios remain the same between 1994 and 1996 even though the number of RDS has been increased.
Conclusion: The receiving special programs would not be increased.

城区V曾经很繁华，而现在V中大部分企业都搬到了郊区。城区的建筑缺少企业运营者需要的现代设施。
为吸引更多的企业来城区，V的官员计划建造许多现代建筑，且减少企业在城区新建筑物里的租赁税率

削弱：郊区吸引大部分企业的不是现代设施？
     郊区的租赁税率比城区低？

UL用森林里的树木生产两种产品。tree trunks 将被制成 lumber ，branches转换成 wood chips来制作fiberboard.
对于conversion费用在a logging site和United's factory是一样的。
however， wood chips占的体积小于制成前树枝的一半

加强：?（没明白怎么回事儿 猜不出来）

50s

enough sunlight & enough seawater reach that layer of ice →M海藻会生长
尽管moderate snow 遮挡了阳光，然而sea ice with moderate snow比sea ice with less snow cover 包含更多的algae in the top layer

解释：太强烈的阳光会阻碍algae的生长？
     雪会融化成 seawater？

50s
RDS传播特殊的信息只有装了RDS的收音机才能收到，在94和96年，V城RDS radio stations 数目由250增加到了600
however 由于V城装了RDS的收音机数目没有变化，V城人民收到特殊信息的人数也没有显著增加
假设：

59s
deluxe air filter 比economy filter多销了50%
但economy filter能用一个月，deluxe air filter 能用两个月
--- To increase repeat sales of our economy filter and maximize profits，我们应集中卖economy filter

推理：更换新的economy filter增加的销售额要比卖deluxe air filter超过economy filter价格的销售额多


逻辑不好，恳求大家的指导！谢谢！

小抽

1premise:对downtown减税 建office
conclusion：吸引lease
weaken：本身在substurd的税就很高（它因削弱）

branches converted into wood chips to make fiberboard 在local 还是factory 总cost一样
但是在工厂中volume只有一半
原因，在工厂中运输费用就占据了一半cost

3algue 能生长在enough sunlight和seawater的时候
有雪使得阳光少了，不过algue却比没有雪的时候多
原因，有雪使得seawater营更好养

4有特定的equipment才能接受某个RDS station的广播
目前增加了station，但是由于equipment的数量不变，因此收听人数不变

assumption：这些新增加的station并不在原来有equipment但是收不到信号的地方

5 d的推广只产生多50%的销量，但是D耗损度是原来的一半，
所以应该继续使用老的

大三准备留学

1.这个地方的发达的商业圈都转移到了郊区，因为市内没有提供商业区舒适的环境，政府想让商业区转移到市内，通过盖新楼并且对于出租地盘的企业见面税务

削弱：舒适的环境最重要了

2.树有二用 树干 树枝  树枝可以先分成条再带走 也可以带走再分 运费不变的  但是先分体积小了一半

得到：先分再带走 便宜啊

3.ALGAE生长需要阳光和海水的营养  但是被MI覆盖的LAWYER里 更少的阳光却有更多的algae

为什么？ 营养更加充足了

4.RDS 只能通过RDS接收器收听  从94到96年  频道多了很多250-600  但是接收器数量是不变的 所以这个地方收听RDS的人数是没有改变的

假设：一个接收器依然只有相同的人数收听。。。

注意argument里面的年代
5.
>causation&correlation: The decreased profits may not due to the deluxe air filter.
>The plan probably would not have its inteded effect. When people found the economy filter are out of service, they would not repeatedly buy them.
>cost-profit: whether the cost in the advertisement about economy filter could be compensated by the discount.
