6.【火警】

6.1

消防局发现报警来自public telephone要多于消防局专门为着火报警设的fire alarm什么的。所以其实不用再专门设那个fire alarm, 因为人们习惯用public telephone报警。

问:weaken    

22. GWD25-Q22.
Springfield Fire Commissioner: the vast majority of false fire alarms are prank calls made anonymously from fire alarm boxes on street corners. Since virtually everyone has access to a private telephone, these alarm boxes have outlived their usefulness. Therefore, we propose to remove the boxes. Removing the boxes will reduce the number of prank calls without hampering people’s ability to report a fire.
Which of the following, if true, most strongly supports the claim that the proposal, if carried out, will have the announced effect?

A.    The fire department traces all alarm calls made from private telephones and records where they came from.
B.    Maintaining the fire alarm boxes costs Springfield approximately five million dollars annually.
C.    A telephone call can provide the fire department with more information about the nature and size of a fire than can an alarm placed from an alarm box.
D.    Responding to false alarms significantly reduces the fire department’s capacity for responding to fires.
E.    On any given day, a significant percentage of the public telephones in Springfield are out of service.

 

7. 【收购】

7.1

一个公司叫Xworld要收购一个叫Xsmart的公司,在这两个公司竞争的城市,world比smart价格低,world在其他城市价格高,所以在这场收购后,world要涨价。

问:削弱 

 

8.【海洋生物】

8.1

一种生物在海里thrive,是由于N含量高,有一个地区N含量高,但是生物不thrive,p认为是Iron含量低,在海里加了Iron后,生物没有明显增长。作者支持p的观点。

问:什么原因能解释这个discrepancy.

8.2

Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface, where plankton live. Nevertheless, some areas, though rich in these nitrogen compounds, have few plankton. These areas have particularly low concentrations of iron, and oceanographers hypothesize that this shortage of iron prevents plankton from thriving. However, an experimental release of iron compounds into one such area failed to produce a thriving plankton population, even though local iron concentrations increased immediately.

Which of the following, if true, argues most strongly against concluding, on the basis of the information above, that the oceanographers' hypothesis is false?

(A)Not all of the nitrogen compounds that are sometimes found in relatively high concentrations in the oceans are nutrients for plankton.
(B)Certain areas of the ocean support an abundance of plankton despite having particularly low concentrations of iron.
(C)The release of the iron compounds did not increase the supply of nitrogen compounds in the area.
(D)A few days after the iron compounds were released, ocean currents displaced the iron-rich water from the surface.
(E)The iron compounds released into the area occur naturally in areas of the ocean where plankton thrive.
weaken 选D

观点3说就算浅海温度不至于让生物decline,但是这种生物吃的东西生活的深海冻死了,导致了浅海生物数量跟着降低。

问:忘了。
