Jeneta: Increasingly, I’ve noticed that when a salesperson thanks a customer for making a purchase, the customer also says “Thank you” instead of saying “You’re welcome.” I’ve even started doing that myself. But when a friend thanks a friend for a favor, the response is always “You’re welcome.”

"Surprising" Phenomenon

Why do we say “You’re welcome” when a friend thanks us for doing him a favor, but when a salesperson thanks a customer for buying something, the customer also says, “Thank you,” instead of “You’re welcome”?

Objective

The correct answer should tell us about a difference between the salesperson-customer context and the friend-friend context that could explain why a customer says “Thank you” whereas a friend says “You’re welcome.”

A
Customers regard themselves as doing salespeople a favor by buying from them as opposed to someone else.

This would lead us to expect customers to say “You’re welcome.”

B
Salespeople are often instructed by their employers to thank customers, whereas customers are free to say what they want.

Even if customers are free to say whatever they want, why do they say “Thank you” instead of “You’re welcome”? This answer doesn’t provide a theory.

C
Salespeople do not regard customers who buy from them as doing them a favor.

This relates to the salesperson’s motivations for she says. But it doesn’t tell us about the customer’s.

D
The way that people respond to being thanked is generally determined by habit rather than by conscious decision.

We have no reason to think that customers would develop a habit of saying “Thank you” instead of “You’re welcome.” This doesn’t provide a theory for how customers began to say “Thank you” to salespeople.

E
In a commercial transaction, as opposed to a favor, the customer feels that the benefits are mutual.

In the salesperson-customer context (commercial transaction), the customer feels benefited, which is why they say “Thank you.” In the friend-friend favor context, the person who does the favor doesn’t necessarily feel mutual benefit. This is why he says “You’re welcome.”

Some video game makers have sold the movie rights for popular games. However, this move is rarely good from a business perspective. After all, StarQuanta sold the movie rights to its popular game Nostroma, but the poorly made film adaptation of the game was hated by critics and the public alike. Subsequent versions of the Nostroma video game, although better than the original, sold poorly.

Summarize Argument

The author concludes that selling the movie rights for popular video games is rarely good for business. He supports this by noting that the film adaptation of Nostroma was hated by critics and audiences, and later versions of the game sold poorly, even though they were better than the original.

Identify and Describe Flaw

This is the cookie-cutter flaw of hasty generalization, where the author draws a broad conclusion based on too little evidence. Here, the author argues that selling the movie rights for video games is usually bad for business, but he only provides one example. Perhaps Nostroma doesn’t accurately reflect most video game movies. Maybe it was just a bad movie, and most video game movies are successful and boost sales.

A
draws a general conclusion on the basis of just one individual case

The author draws a general conclusion about selling the movie rights for video games on the basis of just one individual case: the Nostroma movie. But the Nostroma movie might not accurately reflect the business impact of most video game movie deals.

B
infers that a product will be disliked by the public merely from the claim that the product was disliked by critics

The author explicitly states that the Nostroma movie was hated by both critics and the public. He doesn’t assume that the public will dislike something just because critics disliked it.

C
restates as a conclusion a claim earlier presented as evidence for that conclusion

This is the cookie-cutter flaw of circular reasoning, where the argument’s conclusion merely restates one of its premises. The author doesn’t make this mistake. He draws his conclusion based on an example that is distinct from that conclusion.

D
takes for granted that products with similar content that are in different media will be of roughly equal popularity

The author doesn't assume that games and movies about similar content will be equally popular. If anything, he assumes that the movie version of a popular video game will be significantly less popular.

E
treats a requirement for a product to be popular as something that ensures that a product will be popular

This is the cookie-cutter flaw of confusing necessary and sufficient conditions. The author doesn’t make this mistake. In fact, he never presents a necessary condition for a product to be popular in the first place.

Science writer: Lemaître argued that the universe began with the explosion of a “primeval atom,” a singular point of infinite gravity in space and time. If this is correct, our current observations should reveal galaxies accelerating away from one another. This is precisely what we observe. Yet because there is another theory—the oscillating universe theory—that makes exactly this same prediction, Lemaître’s theory must be considered inadequate.

Summarize Argument
The writer argues that Lemaître’s is inadequate because, although its prediction matches our current observations of galaxies speeding away from each other, the oscillating universe theory makes exactly this same prediction.

Identify and Describe Flaw
The writer presents two theories—Lemaître's theory and the oscillating universe theory—that both predicted our current observations. She then concludes that Lemaître's theory is inadequate just because the oscillating universe theory makes the same prediction.

However, the writer gives no real reason to dismiss Lemaître's theory. What if it is adequate? What if the two theories are actually complementary? Simply pointing out that another theory makes the same prediction isn't enough to prove that Lemaître's theory is inadequate.

A
The conclusion is derived partly from assertions attributed to a purported expert whose credibility is not established.
Presumably Lemaître is a credible expert, but either way, the writer’s argument doesn’t rely on his credibility or the credibility of any other expert. Instead, she addresses the accuracy of two theories’ predictions and the inadequacy of Lemaître's theory.
B
The conclusion is based on a shift in meaning of a key term from one part of the argument to another part.
This is the cookie-cutter flaw of equivocation, where the argument uses the same term in two different ways. The writer doesn’t make this mistake; all of her terms are used clearly and consistently throughout her argument.
C
The science writer takes for granted the existence of a causal connection between observed phenomena.
The writer doesn’t assume that one observed phenomenon caused another. In fact, she only addresses one observed phenomenon in the first place— galaxies accelerating away from each other.
D
The science writer fails to see that one theory’s correctly predicting observed data cannot itself constitute evidence against an alternative theory that also does this.
In other words, the fact that the oscillating universe theory also predicted the observed data doesn't prove that Lemaître's theory is inadequate.
E
The science writer presumes, without providing justification, that there are only two possible explanations for the phenomena in question.
The writer never assumes that Lemaître's theory and the oscillating universe theory are the only explanations for why galaxies are accelerating away from each other. Instead, she assumes that because both theories predicted this phenomenon, Lemaître's theory must be inadequate.
