1. Person 1: Bicycle infrastructure should be expanded because cycling is a sustainable mode of transportation. Person 2: We should not build bike lanes because cyclists run red lights and endanger pedestrians.

Correct Answer: Correct answer is: (D) Straw Man.

Exam Relevance: GRE, LSAT, GMAT, Critical Reasoning exams

Difficulty: Moderate

Concept notes: A Straw Man fallacy occurs when someone misrepresents or exaggerates an opponent's argument to make it easier to attack.

Common Mistakes: A common mistake is to confuse the Straw Man fallacy with other types of logical fallacies, such as Hasty Generalization or Ad Hominem.

Explanations: Person 2's argument misrepresents the original argument by Person 1. Person 1 argues for expanding bicycle infrastructure because cycling is sustainable. Person 2, however, attacks a different issue, claiming that cyclists run red lights and endanger pedestrians. This misrepresentation of the original argument to make it easier to attack is a Straw Man fallacy.

Option Analysis:

Option A: Band Wagon is not applicable here as it involves appealing to popularity rather than misrepresenting an argument.
Option B: Either/Or is not applicable as it involves presenting a false dichotomy, which is not the case here.
Option C: Hasty Generalization involves making a broad conclusion based on insufficient evidence, which is not the case here.
Option D: Straw Man is the correct answer as Person 2 misrepresents Person 1's argument to make it easier to attack.

Mnemonic: Straw Man: Misrepresent, Attack, Misrepresent.

2. How will you judge a student who gives unjustified reasons for what he or she knows was a wrong decision or action, e.g. not conforming to class because its already late?

Correct Answer: Correct answer is: (B) Rationalizing.

Exam Relevance: GRE, GMAT, LSAT, Critical Reasoning Tests

Difficulty: Moderate

Concept notes: Rationalizing refers to providing reasons or explanations that are not based on the true motives or facts, often to justify a wrong decision or action.

Common Mistakes: A common misunderstanding is confusing rationalizing with justifying, which involves providing valid reasons for a decision or action.

Explanations: Rationalizing is the act of providing reasons or explanations that are not based on the true motives or facts, often to justify a wrong decision or action. In this context, a student who gives unjustified reasons for a wrong decision or action is rationalizing their behavior, rather than providing a valid justification or reasoning.

Option Analysis:

Option A: Justifying involves providing valid reasons for a decision or action, which is not the case here.
Option B: Rationalizing involves providing reasons that are not based on true motives or facts, which fits the scenario described.
Option C: Reasoning involves logical thinking and valid arguments, which is not applicable here.
Option D: Clarifying involves making something clear or easier to understand, which is not the focus of the question.

Mnemonic: Rationalizing = Reasontizing (reasons that are not true)

3. When someone attacks a distorted version of the original argument that they have themselves created is called a/an

Correct Answer: Correct answer is: (A) Strawman fallacy.

Exam Relevance: GRE, LSAT, GMAT, Critical Reasoning exams

Difficulty: Easy

Concept notes: A strawman fallacy occurs when someone misrepresents an opponent's argument to make it easier to attack.

Common Mistakes: A common mistake is confusing the strawman fallacy with other logical fallacies, such as the slippery slope fallacy, which involves a chain of exaggerated consequences.

Explanations: The strawman fallacy involves creating a distorted or exaggerated version of an opponent's argument and then attacking that distorted version instead of the original argument. This misrepresentation makes it easier to refute the argument, but it does not address the actual points made by the opponent.

Option Analysis:

Option A: Correct. The strawman fallacy involves attacking a distorted version of the original argument.
Option B: Incorrect. The slippery slope fallacy involves a chain of exaggerated consequences, not a distorted version of an argument.
Option C: Incorrect. An appeal to false authority involves citing an unqualified authority to support an argument, not distorting an argument.
Option D: Incorrect. The correct answer is provided in option A.

Mnemonic: Strawman: "Straw" for "distorted" and "man" for "opponent."
