Beginners typically decide each chess move by considering the consequences. Expert players, in contrast, primarily use pattern-recognition techniques. That is, such a player recognizes having been in a similar position before and makes a decision based on information recalled about the consequences of moves chosen on that prior occasion.

Summary
Beginner chess players decide each move by considering the consequences. In contrast, expert chess players primarily use pattern recognition. For example, expert chess players recognize having been in a similar position before and decide each move based on information recalled about the consequences of that move on a prior occasion.

Strongly Supported Conclusions
Expert chess players primarily rely on their memory when playing chess.

A
Beginning chess players are better at thinking through the consequences of chess moves than experts are.
This answer is unsupported. The stimulus only compares beginner and expert chess players in terms of their techniques. The stimulus does not suggest that either player is better.
B
A beginning chess player should use pattern-recognition techniques when deciding what move to make.
This answer is unsupported. The stimulus does not offer a judgment as to what beginner chess players should do.
C
One’s chess skills will improve only if one learns to use pattern-recognition techniques.
This answer is unsupported. We don’y know from the stimulus whether pattern recognition is a necessary condition for improving chess skills.
D
In playing chess, an expert player relies crucially on his or her memory.
This answer is strongly supported. An expert is relying crucially on his or her memory when they primarily decide their next moved based on information recalled about that move’s consequences.
E
Any chess player who played other games that require pattern-recognition skills would thereby improve his or her chess skills.
This answer is unsupported. We don’t know from the stimulus whether any other activity requiring pattern recognition skills would help a chess player improve their chess skills.

The question stem reads: The argument does which of the following? This is a Method of Reasoning question.

The argument begins by stating, "When a nation is on the brink of financial collapse, its government does not violate free market principles if, in order to prevent financial collapse, it limits the extent to which foreign investors and lenders can withdraw their money." That was a mouthful, so let's break it down. We can remove the embedded clause "in order to prevent financial collapse" and add it to the end of the premise. Now we have: "The government does not violate free market principles if it limits the extent to which foreign investors and lenders can withdraw their money in order to prevent financial collapse." Ok, that makes more sense. It seems like limiting withdrawals violates the free market, so let's see what evidence they offer us. The author describes how the right to free speech does not include the right to yell fire in a crowded theater because there might be harm resulting from the "stampede" to exit the theater. The author claims that yelling fire is analogous to allowing investors to withdraw money during a financial collapse. On the author's accounts, the mad dash to withdraw money can cause just as much harm as the stampede to exit the theater. The author has made an argument by analogy. Arguably a poor analogy, but our job is not to evaluate the strength of the author's argument; it is merely to determine how the argument proceeds.

Correct Answer Choice (A) is precisely what we are looking for. When we map the stimulus to (A), we get: "tries to show that a set of principles (the free market) is limited in a specific way (limiting investors ability withdraw money during financial collapse) by using an analogy to a similar principle (free speech) that is limited in a similar way (not being allowed to yell fire in a crowded theater), precisely what we prephased.

Answer Choice (B) is incorrect. It would be difficult to map the stimulus onto this answer choice. What facts are we trying to explain? There are none, so we can ignore this answer choice.

Answer Choice (C) can be quickly crossed off because the argument contains no experimental results.

Answer Choice (D) is incorrect because the argument does not claim that a certain explanation of an observed phenomenon is wrong.

Answer Choice (E) is incorrect because there is no empirical generalization. The author makes an analogy to the limits of free speech. However, that would not be considered an empirical generalization.

Economist: As should be obvious, raising the minimum wage significantly would make it more expensive for businesses to pay workers for minimum-wage jobs. Therefore, businesses could not afford to continue to employ as many workers for such jobs. So raising the minimum wage significantly will cause an increase in unemployment.

Summarize Argument
The economist concludes that significantly raising the minimum wage will increase unemployment. This is because raising the minimum wage would make minimum-wage jobs more expensive for businesses, leading to layoffs.

Notable Assumptions
The economist assumes that businesses will shoulder the costs of the minimum wage raise, rather than increasing the price of their products and services to account for the new expense. She also assumes that most businesses aren’t currently seeking a substantial number of employees to fill their minimum wage jobs, which if true would suggest that layoffs aren’t imminent.

A
Businesses typically pass the cost of increased wages on to consumers without adversely affecting profits.
The minimum wage raise won’t affect profits. Employers therefore won’t need to lay off minimum-wage workers, at least not for the reason mentioned.
B
When the difference between minimum wage and a skilled worker’s wage is small, a greater percentage of a business’s employees will be skilled workers.
We don’t care about skilled workers. We have no idea if businesses are even looking for skilled workers.
C
A modest increase in unemployment is acceptable because the current minimum wage is not a livable wage.
The economist only cares about how the minimum wage affects unemployment. We don’t care about livable wages.
D
Most workers are earning more than the current minimum wage.
The economist never claimed minimum wage workers constitute the majority of workers. We don’t care that most people earn more than the minimum wage.
E
The unemployment rate has been declining steadily in recent years.
Even if unemployment has been declining, a minimum wage raise may make it rise again. We don’t care about general trends.

Executive: We recently ran a set of advertisements in the print version of a travel magazine and on that magazine’s website. We were unable to get any direct information about consumer response to the print ads. However, we found that consumer response to the ads on the website was much more limited than is typical for website ads. We concluded that consumer response to the print ads was probably below par as well.

Summarize Argument
The executive concludes that consumers’ response to a recent run of print ads in a magazine was probably below the average response to print ads. In support, the executive points out that the consumer response to digital ads on the magazine’s website was below the average response to digital ads.

Describe Method of Reasoning
The executive draws an analogy between two similar cases (print ads and digital ads) to justify drawing conclusions about one based on evidence from the other. This is how the executive comes to a conclusion about the response to the print ads based on response statistics from the digital ads.

A
bases a prediction of the intensity of a phenomenon on information about the intensity of that phenomenon’s cause
The executive doesn’t make predictions based on the cause of a phenomenon. There’s no discussion at all about the “intensity” of whatever might have caused a poor response to the ads.
B
uses information about the typical frequency of events of a general kind to draw a conclusion about the probability of a particular event of that kind
The executive doesn’t draw conclusions about a particular event based on the typical event of that kind. The executive’s conclusion about a particular case, print ads, is drawn from evidence from another particular case, digital ads, which is claimed to be analogous.
C
infers a statistical generalization from claims about a large number of specific instances
The executive doesn’t make any generalizations, and only ever discusses two specific instances—definitely not a large number.
D
uses a case in which direct evidence is available to draw a conclusion about an analogous case in which direct evidence is unavailable
The executive uses the case of digital ads, for which direct evidence of poor consumer response is available, to draw a conclusion that the consumer response was also poor for print ads. This is necessary because there’s no direct evidence about the print ads.
E
bases a prediction about future events on facts about recent comparable events
The executive doesn’t make any future predictions, instead only drawing a conclusion about one recent event based on an analogy to another recent event.
