A volunteer uses a truck to pick up donations of unsold food and clothing from stores and to deliver them to locations where they can be distributed. He drives only along a certain network of roads.
In the network there are two-way roads connecting each of the following pairs of points: 1 with 2, 1 with 3, 1 with 5, 2 with 6, 3 with 7, 5 with 6, and 6 with 7. There are also one-way roads going from 2 to 4, from 3 to 2, and from 4 to 3. There are no other roads in the network, and the roads in the network do not intersect.
To make a trip involving pick-ups and deliveries, the volunteer always takes a route that for the whole trip passes through the fewest of the points 1 through 7, counting a point twice if the volunteer passes through it twice.
The volunteer s home is at point 3. Donations can be picked up at a supermarket at point 1, a clothing store at point 5, and a bakery at point 4. Deliveries can be made as needed to a tutoring center at point 2, a distribution center at point 6, and a shelter at point 7. If the volunteer starts at the supermarket and next is to go to the shelter, the first intermediate point his route passes through must be
2
3
5
6
7
答案：(B)
If starting from home, the volunteer next is to make pickups for the shelter at the supermarket and the bakery (in either order), the first two intermediate points on his route, beginning with the first, must be
1 and 2
1 and 3
2 and 1
2 and 4
4 and 2
答案：(A)
If starting from the clothing store, the volunteer next is to pick up bread at either the supermarket or the bakery (whichever stop makes his route go through the fewest of the points) and then is to go to the shelter, the first two points he reaches after the clothing store, beginning with the first, must be
1 and 2
1 and 3
4 and 2
6 and 2
6 and 4
答案：(B)
If the volunteer is to make a trip starting at the shelter, next going to the bakery for a pickup, and then ending at the distribution center, the first two intermediate points on his route, beginning with the first, can be
3 and 1
3 and 4
4 and 2
6 and 2
6 and 5

When an osprey (a fish-eating hawk) returns from fishing to its nesting area with a fish like an alewife, a pollack, or a smelt, other ospreys will retrace its flight path in hopes of good fishing. There is seldom such a response if the first bird brings back a winter flounder. Yet ospreys feed on winter flounder just as readily as on any other fish.
Which of the following, if true, contributes most to an explanation of the fishing behavior of ospreys as it is described above? Ospreys are seldom able to catch alewives, pollack, or smelt. Alewives, pollack, and smelt move in schools, but winter flounder do not. Winter flounder prefer shallower waters than do alewives, pollack, or smelt. Winter flounder and pollack exhibit protective coloration, but alewives and smelt do not. Ospreys that five in nesting areas are especially successful fishers.
答案：(B)
A recent study of an insurance company s underwriters indicated that those who worked in pleasant physical surroundings were 25 percent more productive than their peers in unpleasant physical surroundings. Objective criteria for evaluating job performance included caseload and complexity of cases. This shows that improving workers environments increases those workers productivity.
Which of the following, if true, most seriously weakens the conclusion above?
On average, less-productive employees spend no fewer hours per day at their workstations than do their more-productive peers.
Unpleasant surroundings give employees less motivation to work hard than more pleasant surroundings do.
The more-productive employees are generally rewarded with pleasant office space.
More-productive employees do not work any more hours than their less-productive peers.
Peer pressure discourages employees in crowded, unpleasant surroundings from making phone calls to their own family members during work time."
答案：(C)
问题:下面哪一个，if true，最能够削弱上面的结论？
读题:一个保险公司的保险业者最近的调查指出：那些在舒适的物理环境工作的人比在不舒适的物理环境工作的同行多产25%。评判工作性能的客观准则包括工作量和工作复杂度。这表明改善工人的工作环境会提高工人的生产力。
分析：
上文结论为倒数第三行this shows引导：改善工人的工作环境会提高工人的生产力。结论是从什么地方得到呢？是从一个study中得出的。从一个事实、一个study、一个survey等得到一个结论，结论往往是对上面的事实、研究、调查作了一个解释。
**判断论据是不是一个事实，只要在后面那句话加个因为，如果通顺的化那么结论就是对论据的解释， 否则的化，就是颠倒过来，前面是原因，后面是结果。对于本题先判断一下：为什么它们高产呢？是因为环境好使他们高产。很通顺，因此本题结论是对上面的study做出了解释。问题是 WEAKEN， 说到这两个方向就是答案：
1、 有其他的原因来解释上面的STUDY (占大多数)
2、 直接说环境好并不一定高产
A.平均来说，低产的雇员每天工作的时间不比高产的雇员少
D.高产的雇员不比低产的同行工作更多的时间（A，D 其实是一样的意思，他们都带有否定词，而且都可以作为ASSUMPTION，表示没有其他的原因来解释上面的研究）
B.不舒适的物理环境比舒适的物理环境给雇员更少的动力去努力工作（用了一个比较，直接说环境好让人努力工作，与结论一致，因此起到SUPPORT作用）
C.效率更高的雇员通常被给以舒适的物理环境指出并不是环境好使他们效率高，而是因为他们效率高了，被给予好的环境，这在逻辑上称为因果顺序颠倒，是比较难的一类错误，在92年10月SECTION 5第24题93年10月SECTION 6第1题都是属于这类题目
In a certain country, individuals tend to change their political affiliation readily from one political party to another. In the past the Union party grew larger because of this tendency, but although most of those who change to a new party affiliation change to the Union party, the Union party has remained about the same size in recent years.
Which of the following, if true, best helps to explain the change in the growth pattern of the Union party mentioned above?
The economy has been prospering recently, and many of those who change party affiliation are upwardly mobile and prosperous.
In recent years those who were previously nonaffiliated have tended to join the Union party if they joined any party at all.
The percentage of voting-age citizens who change political party affiliation each year has remained constant, and the number of voting-age citizens has remained the same.
The percentage of voting-age citizens who are affiliated with any political party has increased over the last ten years.
Many members of the Union party have abandoned all political party affiliation in recent years.
