A
Taxpayers should be allowed to decide whether a portion of their tax dollars is to be used to fund the arts.
Sure, taxpayers can vote for elected representatives who vote against funding the arts if they so choose. But we need a principle that tell us taxpayers aren’t wronged when elected representatives vote to fund the arts, even when the arts are occasionally offensive.
B
The funding of a particular activity is warranted if it is funded by elected representatives who legitimately fund that activity in general.
Funding offensive art is fine so long as elected representatives generally fund the arts. Particular works of art may be offensive, but the arts as a whole are something elected representatives have the right to continue supporting.
C
Elected representatives are within their rights to fund any activity that is supported by a majority of their constituents.
We have no idea if most people support the arts.
D
Those who resent taxation to subsidize offensive art should vote against their incumbent government representatives.
They probably should, but the author isn’t concluding about what taxpayers should do. We need something that tells us taxpayers weren’t treated unjustly by the funding of offensive art.
E
Since taxpayers are free to leave their country if they disapprove of their representatives’ decisions, they have no right to complain about arts funding.
Taxpayers can complain all they like. We need something that tells us they weren’t be treated unjustly by their elected representatives.
"Surprising" Phenomenon
Even though the summer is usually the best for soft-drink sales and Foamy Soda lowered its prices, sales of Foamy Soda dropped during the summer months.
Objective
The right answer will be a hypothesis that does not help to explain why sales of Foamy Soda decreased in the summer, even though the company lowered its prices and the summer months are usually the best for soft-drink sales.
A
The soft-drink industry as a whole experienced depressed sales during the summer months.
This contributes to reconciling the discrepancy because Foamy Soda’s low sales may be a result of an industry-wide decrease in demand. It could be that consumers just did not want as much soda this summer, regardless of the brand.
B
Foamy Soda’s competitors lowered their prices even more drastically during the summer months.
This contributes to reconciling the discrepancy. If Foamy Soda’s competitors lowered their prices more than Foamy Soda did, consumers may have decided to go with the more heavily discounted options.
C
Because of an increase in the price of sweeteners, the production costs of Foamy Soda rose during the summer months.
This does not contribute to reconciling the discrepancy. An increase in production costs does not explain why sales decreased, especially since Foamy Soda lowered its prices.
D
A strike at Foamy Soda’s main plant forced production cutbacks that resulted in many stores not receiving their normal shipments during the summer months.
The stores not receiving their normal shipments, and thus not being able to sell Foamy Soda as they usually do, could explain why sales of the product decreased during the summer months.
E
The weather during the summer months was unseasonably cool, decreasing the demand for soft drinks.
A decrease in demand for soft drinks could explain why Foamy Soda experienced a decrease in sales, even with lower prices.
Summary
The health officials come to the conclusion that watching television negatively influences viewers’ dietary habits. Why? Because on many television programs, characters eat or discuss foods that are extremely low in nutritional value.
Notable Assumptions
The health officials’ claim links together the foods featured on television with an influence over viewers’ dietary habits, which requires assuming that the content of television programs can in fact influence viewers’ behavior in real life. Specifically, it would need to influence viewers to behave more like what they see on television. Otherwise, there’s no connection between seeing low-nutritional-value foods on television and developing worse dietary habits.
A
the eating and drinking habits of people on television programs are designed to mirror the eating and drinking habits of television viewers
This is irrelevant to the question of whether the foods featured on television influence viewers’ dietary habits. As in (C), we don’t care why the foods are featured, just what impact they have.
B
seeing some foods and beverages being consumed on, or hearing them mentioned on, television programs increases the likelihood that viewers will consume similar kinds of foods and beverages
In other words, seeing low-nutritional-value foods on television leads viewers to eat more of those foods, thus worsening their diets. Without this assumption linking television content to poor dietary habits, the argument wouldn’t make sense.
C
the food and beverage industry finances television programs so that the foods and beverages that have recently appeared on the market can be advertised on those programs
Like (A), this focuses on the irrelevant consideration of why certain foods are featured on television. But we don’t need to know why, we only need to know if featuring certain foods can impact viewers’ eating habits.
D
television viewers are only interested in the people on television programs who have the same eating and drinking habits as they do
Whether or not television characters’ dietary habits are interesting to viewers is irrelevant, because it doesn’t get to whether those dietary habits can actually impact viewers’ own dietary habits.
E
the eating and drinking habits of people on television programs provide health officials with accurate predictions about the foods and beverages that will become popular among television viewers
Even if the foods featured on television can help to predict what foods will become popular, that doesn’t tell us that television has a bad influence. To get to that conclusion, we would need to assume that television leads people to eat worse foods, not just different foods.
Summarize Argument
The author concludes that people need not fear that the tourism industry will harm the seaside environment. This is backed up by a long chain of support. First, people in the tourism industry are aware that overdevelopment of the seaside harms the environment. They also know that overdevelopment deters tourists, which harms their industry. Finally, we’re told that people in the tourism industry wouldn’t knowingly harm their own industry.
Identify and Describe Flaw
The author draws a broad conclusion that the tourism industry isn’t a risk to the seaside environment, but the offered support only addresses knowing harm through overdevelopment. The author doesn’t give us any reason to believe that the tourism industry wouldn’t unknowingly harm the environment, or that they wouldn’t harm the environment in a way other than overdevelopment.
A
No support is provided for the claim that excessive development hurts the tourist industry.
The author in fact does support this claim by explaining a mechanism: overdevelopment makes areas less attractive to tourists.
B
That something is not the cause of a problem is used as evidence that it never coexists with that problem.
The author just doesn’t make any claims about whether something coexists with a problem. Specifically, the author doesn’t claim that the tourism industry never coexists with environmental damage.
C
The argument shifts from applying a characteristic to a few members of a group to applying the characteristic to all members of that group.
The entire argument is phrased in general terms, talking about the entire tourism industry and all seaside areas. So, the author never focuses on just a few members of a group.
D
The possibility that the tourist industry would unintentionally harm the environment is ignored.
The author’s support only focuses on the possibility that the tourism industry would knowingly harm the environment to draw a general conclusion that they wouldn’t harm the environment at all. The author just doesn’t address the possibility of unintentional harm.
E
The argument establishes that a certain state of affairs is likely and then treats that as evidence that the state of affairs is inevitable.
The argument never makes a jump from a state of affairs being likely to that state of affairs being inevitable. The entire argument is phrased in general and absolute terms, “likely” doesn’t come into it.
Summary
For up to a year after sale, Jones is responsible for repairing any defects in the roof and roof-supporting parts of the house.
The only roof-supporting walls of the house are the exterior walls.
Jones isn’t responsible for any other repairs.
Very Strongly Supported Conclusions
The only walls that Jones is responsible for repairs on are the exterior walls.
A
Jones did not know of any defects in the roof or roof-supporting components of the house at the time the contract was written
Unsupported. The stimulus gives no indication of what Jones knew.
B
although other components of the house may contain defects, the roof and roof-supporting components of the house are currently free from such defects
Unsupported. The stimulus doesn’t consider the current condition of any part of the house.
C
the contract does not oblige Jones to repair any defects in the house’s nonexterior walls after ownership of the house has been transferred
Very strongly supported. The only things Jones is obliged to repair are the roof and any roof-supporting components. And the only roof-supporting walls are exterior walls. So the nonexterior walls aren’t roof-supporting, meaning Jones isn’t obliged to repair them.
D
Smith will be obliged to repair all structural defects in the house within a year after ownership is transferred, except those for which Jones is responsible
Unsupported. The stimulus doesn’t consider Smith’s obligations at all. We know that Jones has certain obligations for repairs, but that doesn’t mean Smith is responsible for all other repairs. We know nothing of anyone’s obligations except Jones’.
E
in the past Jones has had to make repairs to some of the house’s exterior walls
Unsupported. The stimulus doesn’t consider what repairs have occurred, if any, or who performed those repairs.
Summary
The argument concludes that wooden cutting boards only need to be wiped off in order to prevent bacterial contamination of food cut on them, not washed like plastic cutting boards. This is supported by the claim that bacteria can sink into wooden cutting boards very quickly, rather than lingering on the surface.
Notable Assumptions
The argument jumps straight from bacteria sinking into wooden cutting boards to the conclusion that there must be no need to wash those cutting boards to prevent contamination. This assumes that once food debris is wiped off, there’s no way for the bacteria that penetrated a wooden cutting board to recontaminate the surface.
A
Washing plastic cutting boards does not remove all bacteria from the surface.
Whether or not washing removes all the bacteria from plastic cutting boards is irrelevant—the argument is only concerned with what steps are necessary to prevent contamination for wooden cutting boards.
B
Prevention of bacterial contamination is the only respect in which wooden cutting boards are superior to plastic cutting boards.
The argument doesn’t involve any broad claims about whether wooden or plastic cutting boards are overall superior, so this is irrelevant.
C
Food that is not already contaminated with bacteria can be contaminated only by being cut on contaminated cutting boards.
The argument isn’t concerned with every possible way food can be contaminated, it’s only considering when wooden cutting boards can contaminate food. Other sources of contamination are irrelevant.
D
Bacteria that penetrate into wooden cutting boards do not reemerge on the surface after the cutting boards have been used.
Reemerging after use would be one way for bacteria that penetrated into a wooden cutting board to recontaminate the surface. If we negate this, then bacteria can reemerge, which would mean that wiping the surface clean would not suffice to prevent contamination.
E
Washing wooden cutting boards kills bacteria below the surface of the cutting boards.
What would happen if someone washed a wooden cutting board isn’t relevant to the argument, which claims that washing is not necessary to prevent contamination from wooden cutting boards.
P: Your hypothesis is laughable! What would have been the point of such a person’s writing Homeric epics down? Surely a person who knew them well enough to write them down would not need to read them; and no one else could read them, according to your hypothesis.
Summarize Argument: Counter-Position
P concludes that M is incorrect to hypothesize that the Greek alphabet was invented by someone who knew the Phoenician writing system and wanted to record Homer’s stories. P claims that writing down those stories would have been pointless for such an individual, who would already know those stories without writing them down. Also, no one else would know the newly-invented alphabet and be able to read the stories.
Identify and Describe Flaw
P argues that M’s hypothesis is not convincing because there would be no point for someone to write down a story that they knew, in a new alphabet. However, P’s argument can be criticized for overlooking some convincing possible reasons:
1) the writer might anticipate forgetting the story later, and
2) the writer might teach the new alphabet to others.
A
It fails to demonstrate that the Phoenician alphabet alone could have provided the basis for the Greek alphabet.
P’s argument doesn’t rely on the claim that the Phoenician alphabet alone is the basis for the Greek alphabet. P isn’t making any claims at all about the basis for the Greek alphabet.
B
It incorrectly assumes that the first text ever written in Greek was a Homeric poem.
P simply doesn’t claim, nor rely on an assumption, that the first text written in Greek was a Homeric poem.
C
It confuses the requirements for a complex oral tradition with the requirements of a written language.
P doesn’t make any claims about the requirements of an oral tradition compared to those of a written language.
D
It attempts to demonstrate the truth of a hypothesis merely by showing that it is possible.
P doesn’t attempt to demonstrate the truth of a hypothesis at all, but rather, attempts to cast doubt on the truth of M’s hypothesis.
E
It overlooks the possibility that the person who invented the Greek alphabet did so with the intention of teaching it to others.
P claims that inventing an alphabet to write down Homeric stories would have been pointless partially because no one could have read the stories in a new alphabet. This overlooks the possibility that the writer wanted to teach others the alphabet.
Summarize Argument
The advertisement concludes that the audience’s skin should be regularly moisturized. This is based on an analogy to the earth, which experiences cracking and the loss of its beauty when it is not regularly moisturized.
Identify and Describe Flaw
The advertisement’s flaw is that it uses a bad analogy: it draws a conclusion about one case based on another case that isn’t really relevantly analogous. There’s no reason to believe that a lack of moisturizing will cause the same effects for skin as for the earth, since skin doesn’t have the same material properties as the earth.
A
It treats something that is necessary for bringing about a state of affairs as something that is sufficient to bring about that state of affairs.
The advertisement doesn’t confuse necessary and sufficient conditions in its reasoning. It does treat a lack of moisture as sufficient to cause cracking and loss of beauty in the earth, but never confuses that for a necessary condition.
B
It treats the fact that two things regularly occur together as proof that there is a single thing that is the cause of them both.
The advertisement just doesn’t claim that any two things that regularly occur together have a single shared cause. The only things that occur together here are lack of moisture and dryness, where one causes the other.
C
It overlooks the fact that changing what people think is the case does not necessarily change what is the case.
The advertisement doesn’t make any claims whatsoever about the relationship between what people think and what is actually true.
D
It relies on the ambiguity of the term “infusion,” which can designate either a process or the product of that process.
The advertisement doesn’t rely on an ambiguous use of the term “infusion”. Both times “infusion” is used, it it used to mean that moisture is being provided—it’s consistent, not ambiguous.
E
It relies on an analogy between two things that are insufficiently alike in the respects in which they would have to be alike for the conclusion to be supported.
The advertisement relies on an analogy between the earth and skin to draw a conclusion about the consequences of not moisturizing skin. The earth just doesn’t have the relevant similarities to skin which would be needed for the conclusion to be supported.
