LSAT-7-4-23/LSAT-7-4-24

以下是引用dorbear在2003-12-7 6:49:00的发言：
[face=Verdana]In Order To 有两种情形；一种表达必要条件的逻辑关系，通常是In Order to, Must/Have to; 另外一种不表达逻辑关系，只是表达目的和手段（XDF的逻辑教学在这个地方是错误的）。因此后者并不存在一种充分条件或必要条件的成分在其中。以OG为例子：

132. Passengers must exit airplanes swiftly after accidents, since gases released following accidents are toxic to humans and often explode soon after being released. In order to prevent passenger deaths from gas inhalation, safety officials recommend that passengers be provided with smoke hoods that prevent inhalation of the gases.

Which of the following, if true, constitutes the strongest reason not to require implementation of the safety officials' recommendation?
(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took passengers to leave the cabin.
(B) Some airlines are unwilling to buy the smoke hoods because they consider them to be prohibitively expensive.
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting.
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff.
(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the ariplane.

这是一个典型的目的和措施类型，目的和措施之间既没有必要，也没有充分的逻辑关系。而进行削弱或加强，只要就措施的有效性举出一个正面或反面的例子就可以了。

跟上面相反，LSAT的例子确实前一种情况，有逻辑关系的表达In Order To.... Have to. 了解了以上的区别，就不难判断出各自正确的选项。

23. The workers at Bell Manufacturing will shortly go on strike unless the management increases their wages. As Bell's president is well aware, however, in order to increase the worker's wages, Bell would have to sell off some of its subsidiaries. So, some of Bell's subsidiaries will be sold.
The conclusion above is properly drawn if which one of the following is assumed?
(A) Bell Manufacturing will begin to suffer increased losses.
(B) Bell's management will refuse to increase its worker's wages.
(C) The workers at Bell Manufacturing will not be going on strike.
(D) Bell's president has the authority to offer the workers their desired wage increase.
(E) Bell's workers will not accept a package of improved benefits in place of their desired wage increase. [/face]
