Quote:
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?
Hello again, everyone. I hope the competition is treating you well. (There have been some pretty gnarly questions from both the Quant and Verbal sides.) Although the format of this question, a sort of cross between a logical flaw and similar reasoning question, may seem more LSAT-ish, I like to say that you never know just what may come your way on the exam, and it is fun to push yourself outside your comfort zone, right? This is a competition, after all.
The passage could hardly be shorter. The chef generalizes that what holds in one recipe, a specific ingredient, will hold in another for a similar type of food,
pasta sauce.
Quote:
(A) A banker recognizes a counterfeit bill and estimates that one in every thousand transactions will involve a counterfeit bill.
Now, you could argue that the banker is generalizing here, but we have no reason to believe that this estimate is pulled out of thin air. The chef predicted that the very next recipe would include the same ingredient as the recipe he was examining, based on little more than the page he was looking at; the banker seems to be a bit more calculating.
Quote:
(B) A horse wins a local race, and its owner predicts that the horse will win its next race at the state level.
The context makes everything a little different here. The
next race, as one that has not yet been run, has an indefinite outcome, so the horse owner can make such a prediction without pursuing the same flawed reasoning as the chef—the recipe on the next page of the cookbook cannot change (quantum effects aside) in any discernible way. The owner might simply have a champion racehorse, for all we know, and the prediction could be warranted.
Quote:
(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.
Why would it not? The specificity of the information suggests that through some sort of combination of subgrades,
an overall grade for a collectible trading card is reached. If three judges for an ice skating competition awarded the same points for different aspects of a figure skating routine (e.g., difficulty of jumps and execution) to two different skaters, we have no reason to believe the scores would come out any differently for those two competitors. There is no logical flaw to be found here, even if the answer choice does a good job mimicking the language of the passage.
Quote:
(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.
Do not be fooled by the chef-to-chef connection. We are searching for a similar flaw in
reasoning, not in
situation, and there is little overlap between this answer choice and the passage apart from the word
chef. This
head chef can believe just about anything about the quality of the food. The comparison to the food of other restaurants is not the sort of generalizing we are after.
Quote:
(E) A child learns the pronunciation of “laughter” and reasons that “slaughter” is pronounced with an “f” sound.
This is just what we want. Someone takes a template and generalizes to a similar type of thing. Here, it is a child with language; in the passage, it is a chef with a recipe for pasta sauce. (As a linguistic aside, I do not envy second-language-learners of English for just these sorts of cases. And then there is the difference in pronunciation between British English and American English. At least the British retain the “ah” sound for
a in both words, even if they are slightly different, unlike the
a-as-in-hat and
a-as-in-law pronunciation of the two words in American English. What a nightmare!)
If you had trouble with this one, just remember: your goal is always to follow the logic of the passage. Surface details can become distracting, but logical patterns are the lifeblood of CR.
As always, good luck with your studies.
