Only Canadian films are shown at the Lac Nichoutec Film Festival. This year, most of the films that won prizes at that festival also won prizes at international film festivals.

Summary
The stimulus can be diagrammed as follows:

Notable Valid Inferences
Some of the films that were shown at the Lac festival won prizes at international film festivals.
All the films that won prizes at the Lac festival were Canadian.
Some of the films that won prizes at international film festivals this year were Canadian.

A
This year, most of the Canadian films that were shown at international film festivals won prizes at the Lac Nichoutec Film Festival.
Could be false. We don’t know what percentage of the Canadian films shown at international festivals won at the Lac Nichoutec Film Festival. What if the international film festivals showed 1000 Canadian films, and only 10 films total won prizes at the Lac Nichoutec Film Festival?
B
Most of the Canadian films produced this year were shown at the Lac Nichoutec Film Festival.
Could be false. The stimulus gives us no information about what percentage of Canadian films produced this year were shown at the Lac Nichoutec Film Festival.
C
Some of the films that won prizes at international film festivals this year were Canadian films.
Must be true. When we chain the conditional claims, the “some” relationship becomes clear: all films that won at the Lac Festival were Canadian, and most of those won prizes at international festivals, so at least those films both won at international festivals and are Canadian.
D
This year, not every film that won a prize at the Lac Nichoutec Film Festival was also shown at an international film festival.
Could be false. It’s very possible that every film that won a prize at the Lac Nichoutec Film Festival was also shown at an international film festival—after all, most of them won at the international festivals!
E
This year, at least one film that won a prize at an international film festival was not shown at the Lac Nichoutec Film Festival.
Could be false. Maybe the Lac Nichoutec movies were the best films in the world this year and every international festival winner was shown there! Maybe they were the only movies submitted to the international film festivals! The stimulus does nothing to make this impossible.

Commentator: Many social critics claim that contemporary journalists’ cynical tendency to look for selfish motives behind the seemingly altruistic actions of powerful people undermines our society’s well-being by convincing people that success is invariably associated with greed and mendacity. But the critics’ claim is absurd. The cynicism of contemporary journalists cannot be a contributing factor to the undermining of our society’s well-being, for journalists have always been cynics. Today’s journalists are, if anything, more restrained than their predecessors.

Summarize Argument: Counter-Position
The author concludes that the cynicism of contemporary journalists does not undermine our society’s well-being. This is based on the fact that journalists have always been cynics.

Identify and Describe Flaw
The author assumes that the well-being of society has not been undermined in the past due to journalists’ cynicism. This overlooks the possibility that society has been undermined from the cynicism that has always existed.

A
widespread cynicism is beneficial to the well-being of society
We’re concerned with the cynicism of journalists. The effects of “widespread” cynicism, which would include others besides journalists, doesn’t affect the argument’s reasoning. Also, cynicism being beneficial doesn’t help show that it can undermine well-being.
B
cynicism about the motives of powerful people increases with the amount of information one has about them
Whether cynicism increases the information one has about someone has no impact on whether journalists’ cynicism undermines society.
C
the work of contemporary journalists reflects a cynicism that is not really genuine
Whether journalists’ cynicism is genuine or not genuine is irrelevant; what matters is whether that cynicism undermines the well-being of society.
D
any accurate description of human behavior portrays it as selfish
Whether accurate descriptions of behavior portray such behavior has selfish has no impact on whether journalists’ cynicism undermines society’s well-being.
E
cynicism of this type on the part of journalists has always had a negative effect on the well-being of society
This possibility, if true, shows that the fact journalists have always been cynics does not prove their cynicism doesn’t undermine society’s well-being. This well-being has always been undermined as a result of journalists’ cynicism.

Ditalgame Corporation’s computer video games are subject to widespread illegal copying. To combat this piracy, Ditalgame will begin using a new copy protection feature on its games. Ditalgame’s president predicts a substantial increase in sales of the company’s games once the new copy protection feature is implemented.

Summarize Argument

The president concludes that Ditalgame’s sales will increase significantly once the new copy protection feature is added. This is because Ditalgame's games are frequently pirated, so they are implementing a new feature to help prevent piracy.

Notable Assumptions

The president assumes that the feature will directly boost sales without explaining how. He assumes piracy significantly affects sales, rather than other factors like poor game quality. He also seems to assume that some pirates will buy Ditalgame’s games when piracy is no longer an option, rather than choosing other games to pirate or buy.

A
Ditalgame has spent millions of dollars developing the new copy protection feature, and the company can recoup these costs only if its sales increase substantially.

This suggests that Ditalgame needs more sales in order to make an overall profit. But the president’s conclusion is only about whether Ditalgame will increase its sales. (A) fails to address the connection between reduced piracy and increased sales.

B
Over the last several years, the market for computer games has grown steadily, but Ditalgame’s share of that market has shrunk considerably.

The fact that Ditalgame’s share of the game market has shrunk doesn’t tell us whether the copy protection feature will increase sales. (B) fails to address the connection between reduced piracy and increased sales.

C
The copy protection feature causes a copied game to be playable just long enough for most people to come to enjoy it so much that they decide they have to have it.

This provides one explanation for how the copy protection feature could cause a significant increase in sales: by leading some pirates to buy the game.

D
Game Review Monthly, the most commonly read magazine among people who frequently copy computer games, generally gives favorable reviews to Ditalgame games.

This might help explain why Ditalgame’s games are subject to widespread illegal copying, but it doesn’t help explain how the new copy protection feature will increase sales. (D) fails to address the connection between reduced piracy and increased sales.

E
Computer games produced by Ditalgame are copied more frequently than computer games produced by Ditalgame’s main competitors.

We already know that Ditalgame’s games “are subject to widespread illegal copying.” It doesn’t matter if they’re copied more than their competitors’ games. (E) fails to address the connection between reduced piracy and increased sales.
