The mayor has been accused of taking a bribe based on the fact that a consultant that does business with the city paid for improvements to the mayor’s vacation house. In his own defense, the mayor has said that he paid every bill for those improvements that was presented to him.

Summarize Argument
The mayor implies his conclusion: he didn’t take a bribe. He supports this claim by stating that he paid every bill presented to him for home improvements.

Notable Assumptions
In order for the mayor not to have taken a bribe, he must not have only paid every bill presented to him, but also not been aware of any bills that were paid without him knowing.

A
Authorities are investigating the consultant for taking bribes from officials of other cities.
We don’t care if the consultant took bribes. We only care if the mayor did.
B
The mayor was aware that many of the bills were being presented to the consultant rather than to the mayor.
The mayor paid every bill presented to him, but he knew many bills were being presented to the consultant, as well. Thus, his defence falls apart.
C
The building contractor in charge of the improvements to the mayor’s house had done business with the city in the past.
That contractor could still have offered a bribe. We don’t care if they have an employment history with the city.
D
The improvements to the mayor’s house were done with expensive materials and involved thousands of hours of labor.
We don’t care what those improvements were. We care who paid for them.
E
The amount of money that the city paid the consultant over the last year greatly exceeded the cost of the improvements to the mayor’s house.
The amount the city paid the consultant and the costs of the home improvements have nothing to do with each other. We simply care if the mayor took a bribe.

Reviewer: Almost all books that offer management advice are written from the perspective of the CEO. But most managers aren’t CEOs and don’t have the same perspective as CEOs. So the advice in management books is of limited use for most managers.

Summary
The author concludes that the advice in management books is of limited use for most managers. This is based on the following:
Most management books offer advice from the perspective of the CEO.
Most managers don’t have the same perspective as CEOs.

Missing Connection
Why can’t a manager benefit from advice that isn’t written from their perspective? The premises never establish that in order to be of more than limited use, advice must be written from one’s own perspective.

A
Advice books rarely take the perspective of their intended audience.
(A) doesn’t establish anything about what is of “limited use.” We still have no idea why advice from the perspective of someone besides a manager can’t be of great use to a manager.
B
Most people who read management advice books aspire to be CEOs.
(B) doesn’t establish anything about what is of “limited use.” We still have no idea why advice from the perspective of someone besides a manager can’t be of great use to a manager.
C
Almost all CEOs have experience as lower level managers.
(C) doesn’t establish anything about what is of “limited use.” We still have no idea why advice from the perspective of someone besides a manager can’t be of great use to a manager.
D
Advice is of limited use unless it is offered from the perspective of the recipient.
(D) establishes that if advice is not offered from the perspective of the recipient — in this case, managers — then it will be of limited use. This is why advice from the perspective of CEOs, which is different from a manager’s perspective, is of limited use to most managers.
E
Most managers prefer to read books that they think will be useful to them in their work.
(E) doesn’t establish anything about what is of “limited use.” What managers “think will be useful” doesn’t establish that something is of limited use. We still have no idea why advice from the perspective of someone besides a manager can’t be of great use to a manager.

Successful stand-up comedians are able to keep the attention of a large audience for a few hours, in such a way that the audience remembers long afterwards what the comedian said. And in their routines, many comedians make interesting points about serious topics. Unsurprisingly, humor is the means through which comedians are able to accomplish all of this. University professors hope to achieve much the same in their lectures. Thus, _______.

Summary
Successful stand-up comedians keep the attention of their audiences for a few hours and in a way that the audience long after the performance remembers what the comedian said. Additionally, some comedians make points about serious topics in their routines. Comedians are able to accomplish all of these qualities through the use of humor. University professors hope to achieve these same qualities through their lectures.

Strongly Supported Conclusions
Thus, the use of humor in lectures could help university professors achieve these qualities.

A
stand-up comedians and university professors have the same skill set
We don’t know anything about the skill set of a university professor. We only know about the qualities university professors hope to achieve through lectures.
B
incorporating humor into lectures can help professors to achieve the goals they have for those lectures
If the analogy between stand-up comedians and university professors holds, then the use of humor could help university professors achieve their goals for lectures.
C
university professors can achieve the goals they have for their lectures only if they incorporate humor into them
We don’t know if humor is the only means university professors could achieve their goals for lectures. The stimulus suggests that humor is one way, but not necessarily that humor is the only way.
D
there is no reason to suppose that a lecture lasting several hours cannot hold an audience’s attention
We don’t know that there’s no reason to think that lectures cannot keep an audience’s attention.
E
university professors should treat even the most serious topics in a humorous way
We don’t know what university professors should do. The stimulus only suggests that humor could help university professors achieve the goals they have for lectures.

For the first few weeks after birth, the dunnart has such poor control over its respiratory muscles that it cannot use them to breathe. Instead, this tiny marsupial breathes through its thin skin, which gradually thickens as the dunnart matures inside its mother’s pouch. The dunnart is unique among warm-blooded animals, the rest of which need thick skin throughout their lives to maintain body temperature and reduce water loss.

"Surprising" Phenomenon

Why do dunnarts, which are born with thin skin, survive even though all other warm-blooded animals need thick skin from birth in order to maintain their body temperature and reduce water loss?

Objective

The correct answer will be a hypothesis that explains a key difference between how young dunnarts maintain their body temperature and reduce water loss and how all other warm-blooded animals maintain their body temperature and reduce water loss. This difference will help to explain how dunnarts can survive with thin skin at the beginning of their lives, while all other warm-blooded animals need thick skin from birth.

A
The dunnart’s respiratory muscles begin to develop a few days after birth.

We know that baby dunnarts breathe through their thin skin because they cannot yet control their respiratory muscles. But (A) does not explain how they maintain their body temperature and reduce water loss before those respiratory muscles develop.

B
The dunnart’s body temperature is higher than that of many other warm-blooded animals.

Having a higher body temperature does not explain how baby dunnarts maintain that body temperature and reduce water loss with thin skin.

C
Adult dunnarts experience more heat and water loss through their skin than other adult marsupials do.

Dunnarts’ skin gradually thickens as they mature. So we know that adult dunnarts can maintain their body temperature and reduce water loss, even if they don’t do so as efficiently as other adult marsupials. We need an explanation for how baby dunnarts can do this with thin skin.

D
Its mother’s pouch keeps a newborn dunnart warm and reduces water loss through its skin.

This explains the key difference in how young dunnarts maintain body temperature and reduce water loss. While other warm-blooded baby animals need thick skin to survive, its mother’s pouch keeps a baby dunnart warm and reduces water loss, so the baby can survive with thin skin.

E
Some dunnarts live where daytime temperatures are high and the climate is dry.

This does not help to explain how baby dunnarts can survive with thin skin. Even if they are in a warmer and drier climate, we still need to know how they are able to maintain their body temperature and reduce water loss.

Film director: Although the production costs of my latest film are very high, there is little risk that the film studio will not recover these costs. Even if the film is unpopular, much of the money is being spent to develop innovative special-effects technology that could be used in future films.

Summarize Argument
The film director concludes that there’s little risk of the studio losing money on his new movie despite its high costs. This is because some of the money is being spent on special-effects technology will be used in future films.

Notable Assumptions
The film director assumes that much of the cost of the movie is being put towards developing innovative special-effects technology. If that cost was instead being put towards paying actors or elaborate set design, then the studio wouldn’t be likely to recover costs from a box-office failure. The film director also assumes that the technology will in fact be used in future films. If the technology was never used again, or only used in films that fail, then the studio wouldn’t be likely to recover costs.

A
Because the film studio owns the new technology, the studio will be able to control its use in any future films.
This supports the film director’s argument. The technology will be exclusive to the studio, which will perhaps give the studio the upper-hand over competitors later on.
B
Films that introduce innovative special-effects technologies generally draw large audiences of people who are curious about the new effects.
This suggests the film director’s film will be successful. We care about what will happen if it isn’t successful.
C
The production costs of this film are so high that, even if the film is popular, it is unlikely that the film’s ticket sales will offset those costs.
The film director accounts for scenarios where the film loses money. She argues that the studio will nevertheless recover those costs.
D
In the past, many innovative special-effects technologies were abandoned after the films for which they were developed proved to be unpopular.
The special-effects technology might never be used again. Since that’s the only way the film director sees the studio recovering costs, this defeats the film director’s argument that it’s “likely” the studio will recover costs.
E
The use of the new special-effects technology would lower the production costs of other films that use it.
This supports the film director’s argument. The special-effects technology will save the studio money in the long run.

For a work to be rightly thought of as world literature, it must be received and interpreted within the writer’s own national tradition and within external national traditions. A work counts as being interpreted within a national tradition if authors from that tradition use the work in at least one of three ways: as a positive model for the development of their own tradition, as a negative case of a decadent tendency that must be consciously avoided, or as an image of radical otherness that prompts refinement of the home tradition.

Summary

For a work to be considered world literature, it must be received and interpreted by the writer’s own national tradition and by other national traditions. A work is interpreted by a national tradition if writers from that tradition use it in at least one of three ways: as a positive model for the development of their tradition, as a negative model to avoid in the development of their tradition, or as a way to refine the development of their tradition.

Strongly Supported Conclusions

A work can be a negative model in some contexts and a positive model in others and still be considered world literature.

In order to be interpreted by a national tradition, a work of literature must affect the development of that tradition in some way.

A
A work of literature cannot be well received within an external national tradition if it is not well received within the writer’s own national tradition.

Unsupported. The stimulus doesn’t connect the the writer’s own national tradition with external national traditions. Perhaps a work can still be received well in an external tradition without being received well in the writer’s own tradition.

B
A work of world literature offers more to readers within external national traditions than it offers to readers within the writer’s national tradition.

Unsupported. The stimulus does not give any information about what a work of world literature offers to different audiences.

C
A work should not be thought of as world literature if it is more meaningful to readers from the writer’s national tradition than it is to readers from external national traditions.

Unsupported. Whether a work is more meaningful to one group or another has no effect on whether it should be thought of as world literature.

D
A work of world literature is always influenced by works outside of the writer’s national tradition.

Unsupported. For a work to be world literature, it must be received and interpreted by the writer’s own national tradition and by other national traditions. We aren’t told that it’s always influenced by other works outside of the writer’s national tradition.

E
A work is not part of world literature if it affects the development of only one national tradition.

Strongly supported. A work of world literature must be interpreted by the writer’s national tradition and other national traditions. Thus, it must affect the development of both traditions either as a positive model, a negative model, or a model of refinement.

Businessperson: Because the parking area directly in front of the building was closed for maintenance today, I was late to my meeting. If the maintenance had been done on a different day, I would have gotten to the meeting on time. After finding out that I could not park in that area it took me 15 minutes to find an available parking space, making me a few minutes late.

Summarize Argument
The businessperson concludes that she would’ve been on time for her meeting if parking area maintenance had been done on a different day. This is because it took her 15 minutes to find parking since the parking area was closed for maintenance, hence why she arrived late.

Notable Assumptions
The businessperson assumes that she would’ve been on time if the parking area hadn’t had maintenance going on. This means she assumes that she would’ve been able to find parking in the parking area if it had been open.

A
What were the reasons for performing maintenance on the parking area directly in front of the building on that particular day?
We don’t care why maintenance was being performed. We care if the maintenance actually made the businessperson late for her meeting.
B
Were any other of the meeting attendees also late to the meeting because they had difficulty finding parking?
We don’t know if other meeting attendees drove to the meeting. Even if none of the others were late because of parking, it could just be that those people took the bus or walked to work.
C
What are the parking patterns in the building’s vicinity on days when the parking area in front of the building is open?
If the parking area is generally crowded, perhaps to the point of being full, then maintenance wasn’t the problem as the businessperson claims—she wouldn’t have found parking, anyway. If the parking area is generally empty, she would’ve found parking.
D
Does the businessperson have a tendency to be late to meetings?
We don’t care if she’s often late to meetings. It could still be she would’ve been on time if not for the maintenance.
E
Was it particularly important that the businessperson not be late to this meeting?
Irrelevant. How important this meeting was has no bearing on why the businessperson was late.
