Summarize Argument
Election results don’t represent people’s raw opinions. This is because strategists employ techniques to manipulate public opinion for political campaigns.
Notable Assumptions
The author assumes that political strategists’ efforts actually impact people’s behaviours. It could be that the strategists adopt the advertisers’ strategies, and people aren’t affected.
A
Public opinion can be manipulated more easily by officials of nondemocratic governments than by those of democratic governments.
This does not affect the argument. Nondemocratic governments—and how easily they can influence opinion—is not relevant to the argument, which only discusses democratic governments.
B
Advertisers’ techniques are often apparent to the people to whom the advertisements are directed.
This does not affect the argument. We don’t know if people being aware of techniques impacts whether they’re influenced or not. People may be aware of these tactics and still be influenced (or not). We’d have to make too many assumptions for this to have an impact.
C
Many democratic countries have laws limiting the amount that may be spent on political advertisements in any given election.
This does not affect the argument. There may be a huge budget or a small one—we’d have to make too many assumptions for this to have any impact.
D
People who neither watch television nor read any print media are more likely to vote than people who do one or both of these activities.
This does not affect the argument. The possibility that there are people who do not consume media, and thus aren’t exposed to the strategists’ techniques, does nothing to strengthen the argument that election results don’t represent people’s raw preferences.
E
Unlike advertisements for consumer products, most of which only reinforce existing beliefs, political advertisements often change voters’ beliefs.
This strengthens the argument that election results don't represent people’s raw beliefs by telling us that political ads often change people’s preexisting beliefs. Thus, the conclusion (and its link to the impact of political ads) is strengthened.
Terry: That’s absurd. Chemical pollution can cause physical harm, but the worst harm that cellular phones can cause is annoyance.
Summarize Argument: Counter-Position
Terry concludes that Kris is “absurd” to claim that the cellular industry must be regulated the same way as the chemical industry because they both produce a form of pollution. Terry supports this position by claiming that chemical pollution is more harmful than the noise pollution produced by cell phones.
Describe Method of Reasoning
Terry counters Kris’s argument by rejecting Kris’s analogy. Kris claims that two industries should be similarly regulated by analogizing their harmful consequences, and Terry counters by claiming that the harms presented by Kris as analogous are very different in severity.
A
questioning the reliability of the source of crucial information in Kris’s argument
Terry doesn’t question the reliability of Kris’s information sources. All Terry questions is Kris’s use of an analogy.
B
attacking the accuracy of the evidence about the chemical industry that Kris puts forward
Terry doesn’t claim that Kris is making any false claims about the chemical industry, only that the analogy Kris makes between the chemical and cellular industries is weak.
C
arguing that an alleged cause of a problem is actually an effect of that problem
Terry doesn’t make any arguments against Kris based on wrong causality.
D
questioning the strength of the analogy on which Kris’s argument is based
By denying that the harms of chemicals are comparable to the harms of cell phones, Terry questions the strength of the analogy that Kris uses to support the argument that chemicals and cell phones should be similarly regulated.
E
rejecting Kris’s interpretation of the term “technological progress”
Terry does not reject Kris’s interpretation of the term “technological progress,” or even discuss it at all.
A
fails to consider the possibility that the trunks of other cars may pop open when those cars hit potholes
The argument concerns Cynthia’s car and what caused it to pop open. The author does not have to have any belief about whether other cars’ trunks can pop open due to potholes.
B
fails to consider the possibility that potholes can have negative effects on a car’s engine
The argument concerns the cause of Cynthia’s trunk popping open. Whether the engine was affected has no bearing on the cause of the trunk popping open.
C
presumes, without providing justification, that if one event causes another, it cannot also cause a third event
The author did not reason that the trunk couldn’t have popped open from a pothole because the pothole already caused something else.
D
fails to consider the possibility that one type of event can be caused in many different ways
The author overlooks that one type of event (Cynthia’s trunk popping open) can be caused in many different ways. This points out that even if the trunk popped open for other reasons on other occasions, it could have popped open on this occasion due to a pothole.
E
presumes the truth of the claim that it is trying to establish
The author did not assume the conclusion as part of the reasoning. The reasoning involves other occasions on which the pothole popped open. It doesn’t involve a restatement of the conclusion that on this occasion the trunk didn’t pop open from a pothole.
Summary
From the stimulus, we learn that all journalists are against lying. However, journalists aren’t in total agreement about everything. Some journalists think that spoken words should always be quoted verbatim, and other journalists think that it’s fine to tighten up the wording if necessary. Also, some journalists believe that it’s lying to not identify oneself as a journalist, while others believe that it’s acceptable to do so to expose wrongdoing.
Strongly Supported Conclusions
We can infer that not all journalists agree about what counts as lying. We know this because all journalists oppose lying, but only some journalists think that tightening quotes or obscuring their status as journalists would be prohibited by that rule.
A
Reporters make little effort to behave ethically.
This is anti-supported by the stimulus. The author explains that reporters try to act ethically by avoiding lying, as well as providing some details about what that means to different reporters. This all entails at least some effort to behave ethically.
B
There is no correct answer to the question of whether lying in a given situation is right or wrong.
The stimulus does not support this conclusion. The author is just talking about what journalists believe, and makes no absolute moral claims about right and wrong. Also, even if the journalists’ beliefs are “correct,” they’re pretty clear that lying is always wrong.
C
Omission of the truth is the same thing as lying.
This is not supported by the stimulus. While the author tells us that some journalists believe this, some also do not. Because the author doesn’t directly take a stance, we can’t say whether or not an omission truly counts as a lie.
D
Since lying is permissible in some situations, reporters are mistaken to think that it is absolutely taboo.
This is not supported. The author never directly says whether lying is ever permissible—all we know is the journalists’ opinion, so it’s impossible to compare that to an absolute moral truth.
E
Reporters disagree on what sort of behavior qualifies as lying.
This inference is strongly supported. The author explains that all journalists oppose lying. However, some journalists think omission can be acceptable (meaning, it’s not lying), while others think it counts as lying. So, journalists (or reporters) can disagree.
"Surprising" Phenomenon
Why did the masonry house withstand the recent earthquake better than the adjacent wood-frame house, when wood-frame houses are generally better-equipped to withstand earthquakes?
Objective
Any hypothesis that will resolve this will need to explain why, in this certain situation, the two houses didn’t demonstrate what we know about masonry and wood-framed houses in general. The explanation must account for some quirk about the houses themselves that allowed the masonry house to withstand the earthquake better than the wood-frame house.
A
In earthquake-prone areas, there are many more wood-frame houses than masonry houses.
We need to know why the wood-frame houses didn’t perform as well as the masonry house, despite what we know about the two house types. We don’t care about how many houses there are in earthquake zones on average.
B
In earthquake-prone areas, there are many more masonry houses than wood-frame houses.
Same as with answer (A), we don’t care about earthquake zones in general. We need to know about these specific houses.
C
The walls of the wood-frame house had once been damaged in a flood.
If the walls of the wood-frame house had been damaged in a flood, its ability to withstand an earthquake would certainly be weakened. This explains why it didn’t hold up as well as the masonry house did.
D
The masonry house was far more expensive than the wood-frame house.
We don’t care how much the masonry house cost. A masonry house is still a masonry house, and those shouldn’t hold up as well as wood-frame houses during earthquakes.
E
No structure is completely impervious to the destructive lateral forces exerted by earthquakes.
Well, this would be true for both houses. We need something that explains why the wood-frame house underperformed versus the masonry house, given what we know about wood-frame and masonry houses in general.
