2系列最后一波~~




1. Jennifer:  Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.  The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.
Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?
(A) In 1994 Videorama rented out more videos than it sold.
(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville.
(C) Most of the video rental outlets in Centerville rent videos at a discount on certain nights of the week.
(D) People often buy videos of movies that they have previously seen in a theater.
(E) People who own videos frequently loan them to their friends.


Key: E


2. Most of the world's supply of uranium currently comes from mines.  It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market.  Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.


Which of the following would it be most useful to determine in evaluating the argument?
(A) Whether the uranium in deposits on land is rapidly being depleted
(B) Whether most uranium is used near where it is mined
(C) Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater
(D) Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land
(E) Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater


Key: A


3. Traces of cultivated emmer wheat have been found among the earliest agricultural remains of many archaeological sites in Europe and Asia.  The only place where the wild form of emmer wheat has been found growing is a relatively narrow strip of southwest Asia.  Since the oldest remains of cultivated emmer wheat yet found are from village sites in the same narrow strip, it is clear that emmer wheat was first domesticated somewhere in that strip.


Which of the following, if true, most strengthens the argument?


(A) The present-day distribution of another wild wheat, einkorn, which was also domesticated early in the development of agriculture, covers a much larger area of southwest Asia.
(B) Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains. (Irrelevant)
(C) At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated.
(D) In the region containing the strip where wild emmer wheat has been found, climatic conditions have changed very little since before the development of agriculture.
(E) It is very difficult, without genetic testing, to differentiate the wild form of emmer wheat from a closely related wild wheat that also grows in southwest Asia.


Key: D


4. From 1978 to 1988, beverage containers accounted for a steadily decreasing percentage of the total weight of household garbage in the United States.  The increasingly widespread practice of recycling aluminum and glass was responsible for most of this decline.  However, although aluminum recycling was more widely practiced in this period than glass recycling, it was found that the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans.


Which of the following, if true of the United States in the period 1978 to 1988, most helps to account for the finding?


(A) Glass bottles are significantly heavier than aluminum cans of comparable size.
(B) Recycled aluminum cans were almost all beverage containers, but a significant fraction of the recycled glass bottles had contained products other than beverages.
(C) Manufacturers replaced many glass bottles, but few aluminum cans, with plastic containers.
(D) The total weight of glass bottles purchased by households increased at a slightly faster rate than the total weight of aluminum cans.
(E) In many areas, glass bottles had to be sorted by color of the glass before being recycled, whereas aluminum cans required no sorting.


Key: C


5.
The following appeared as part of a column in a popular entertainment magazine:
“The producers of the forthcoming movie 3003 will be most likely to maximize their profits if they are willing to pay
Robin Good several million dollars to star in it—even though that amount is far more than any other person involved
with the movie will make. After all, Robin has in the past been paid a similar amount to work in several films that were
very financially successful.”

1  25s
premise： the total amount of videos which were sold in 1994 was less than in 1993.
premise:   a new video renter called videorama was opened in this area, it the first company notonly rent the video but also sell them in low price.
conclusion: because the opening of the videodrama, the sales volume droped.  
guess: give an other reason~people' habit changed. making a pool,one rent,and several friends watch together .
choice:E

2  32s
pemise: U from mine, a new plan: extract U from S,but cost a lot
conclusion:the plan is not viable until the cost of it will reduce.
guess：。。。。
choice
错了。。。A depleted：耗尽的
就是说：如果陆地上的U很快就会被耗尽的话，那么人们也很快就会需要从seawater中提取U，那时，不论花费有没有降低，都只能提取了~
而D，只是说海中的比陆地的多，如果陆地的没有耗尽，海中的U再多，人们还是会选择相对便宜的陆地的U。所以海中U的多与不多，与人们开不开采没有必然联系，不能起到加强或削弱这个argument的作用。
对不？

1.30S
BG：the rental in 1994 is fewer than 1993
PR：the decline is due to V,which not only rent vidios,but also sold them cheaply.
E

2.35S
BG:U is usually extracted from mine.
PR:the method to extract from seawater cost greater than market price.
con:if the method about from seawater won't reduce,this method can't be viable.
A

3.回视了n次....
BG:the EW was found cultivating eariest in Europe and ASia,
PR: 1.the wide was found only in a trip in southwest Asia.
   2.the oldest remains are found from near that strip.
CON:the EW was firstly domesticated in that trip.
D
4.50s..（刚看太快了没记住回视..这题又看太慢了..垮掉）

BG:beverage containers set less percentage in household garbage in 1978—1988 because of the recycling of aluminum and glass.
PR:A has better recycling than G. but G's weight decline greater than A.

推断：A基数没有G大。
A。

5.40S。
if the movie 3003  make more profit,the producer will pay R much more money than any other actors.but R is paid the same in the past and financially successful.

flaw:1.R其他电影好或许因为编剧好，或者其他因素。R不是唯一的因素。
    2.R或许引起了别人的视觉疲劳，还不如少花点钱找新人来演电影。
    3.R成名的电影不一定是3003这种类型。或许R不适合这种类型的电影。

1 Premise: video rental outlets in 1994 was 10000 fewer than those in 1993 in C
Conclusion: the decline was due to the only video rental outlet in C sold them cheaply
Weaken: maybe due to other reasons such as people like to borrow videos from their friends  
E

2 Premise: extracting uranium from seawater costs more than fetching uranium on the market
Conclusion: if the cost of extracting uranium from seawater doesn’t reduced, this method will never be used
A


3 premise: the wild form of emmer wheat was found in a relatively narrow strip of southwest Asia, and the oldest emmer wheat was found in the same place
Conclusion : the emmer wheat was domesticated in that trip
C
错了  晚上刚看完这个题型的总结  刚刚再做已经能做对了


4 premise1: beverage containers was less in the total weight of household garbage since the increasingly widespread practice of recycling aluminum and glass
Premise2: aluminum recycling was more widely practiced
Conclusion: the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans
C
