GMAT Club World Cup 2022 (DAY 5): A chef is studying a cookbook on the

The chef assumes that a single ingredient would remain common in recipes in the cookbook

(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill.
--> Not parallel as the banker predicts a pattern and not a commonality in the bills

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level.
The horse (garlic equivalent) is expected to play the same role in the next race (recipe equivalent). Looks good.

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade.

(D) A restaurant is awarded a Michelin star, but its head chef believes that the restaurant serves better food than other restaurants awarded one Michelin star.
--> No common pattern here

(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound.
--> The looks parallel as the reasoning for having a similar word (pasta parallel) but the "f" sound (garlic) is being assumed to remain common. However, in this case the word is known and the logic is refuted

IMHO Option B

In this argument, the chef predicts the ingredients of a different sauce will also call for garlic. The chef generalizes that all sauce have garlic in them.

(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill.

This is incorrect.

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level.

This is close, however there is a change in the race level in this option. Hence will eliminate.

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade.

The chef does not think that if garlic is added we are preparing sauce, hence this option is incorrect.

(D) A restaurant is awarded a Michelin star, but its head chef believes that the restaurant serves better food than other restaurants awarded one Michelin star.

I dont suppose this is related anyways.

(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound.

This seems correct. Because the child knows how laughter is pronounced (the components that go in pronunciation), he / she thinks that the same composition applies to another word of the same type.

IMO E

So, the flawed reasoning of the chef here is that because 1 recipe in a cookbook has garlic in its pasta sauce, the next one will as well
We need to find an answers which mimics the flawed reasoning of the chef

Let us examine the options:

(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill.

Banker thinks that one in every thousand will be same, the chef thinks the next one itself. ELIMINATE

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level.

Yes, close one but not really mimicking the chef's logic. ELIMINATE

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade.

If it would have said that the next card to come will have the same overall grade, that would have made it a good option but this says that the next one to have these features will get this grade. ELIMINATE

(D) A restaurant is awarded a Michelin star, but its head chef believes that the restaurant serves better food than other restaurants awarded one Michelin star.

Not even close to the logic of the chef. ELIMINATE

(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound.

YES! child learns a pronunciation of laughter with f and thinking that slaughter (a different word) also having laughter should also have an f sound. Similar to the chef, who thought that because 1 recipe had garlic, the next one will too

Answer - E

A chef is studying a cookbook on the regional flavors of Tuscany. He learns a recipe for pasta sauce in which garlic is added to a tomato base. He predicts that a recipe on the next page to make a different pasta sauce will also call for garlic.

Which of the following most closely parallels the flaw in the cook’s reasoning?


(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill.

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level.

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade.

(D) A restaurant is awarded a Michelin star, but its head chef believes that the restaurant serves better food than other restaurants awarded one Michelin star.

(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound.

Argument structure is to predict(opinion) outcome(garlic use) of next thing(sauce on next page) because both belong to similar type (tuscony cuisine sauce)

(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill. - estimation is different from opinion .. Incorrect

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level. -- type (level) is different (local vs state) -- Incorrect

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade. -- sum of grades in four criteria is same given overall grade .. this is again prediction based on opinion and not addition .. Incorrect
(D) A restaurant is awarded a Michelin star, but its head chef believes that the restaurant serves better food than other restaurants awarded one Michelin star. .. OUt of scope.. Incorrect

(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound... Opinion and similar structure.. CORRECT


Ans E

ANSWER B

Key takeaway: Just because something happened once in the past, the chef predicts it will happen again. Also sound reasoning is provided in this scenario. We are looking for something that could be a coincidence


(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill. This is incorrect, because this prediction has logic and probability behind it

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level. CORRECT

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade. This is based on specific probabilities and weights which are clearly defined. Here the outcome can be predicted via sound reasoning. Hence this is not the same as the passage mentioned above.

(D) A restaurant is awarded a Michelin star, but its head chef believes that the restaurant serves better food than other restaurants awarded one Michelin star. Here a comparison is done, which is not in case with the passage mentioned above

(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound. Here the child's reasoning is sound since the suffix of both words is the same hence the pronunciation should be same.

A chef is studying a cookbook on the regional flavors of Tuscany. He learns a recipe for pasta sauce in which garlic is added to a tomato base. He predicts that a recipe on the next page to make a different pasta sauce will also call for garlic.

Which of the following most closely parallels the flaw in the cook’s reasoning?


(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill. Incorrect

second part is not in parallel

(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level. Incorrect

local race and state level race are not same

(C) To generate an overall grade for a collectible trading card, a grader assigns a numerical value to each of four criteria—corners, edges, centering, and surface. He concludes that the next card to earn the same four subgrades will also be assigned the same overall grade. Correct
