Exam Relevance: GRE, GMAT, LSAT, SAT

Difficulty: Moderate

Concept notes: Logos is a rhetorical device that appeals to logic and reason. It involves using facts, statistics, and logical arguments to persuade the audience.

Common Mistakes: A common misunderstanding is confusing logos with pathos (appeal to emotion) or ethos (appeal to credibility or authority).

Explanations: Logos relies on logic and data to make a persuasive argument. It uses facts, evidence, and rational reasoning to support a claim, making it distinct from emotional or ethical appeals.

Option Analysis:

Option A: Emotion is not the focus of logos; it is more aligned with pathos.
Option B: Experience or expertise is more aligned with ethos, which appeals to credibility or authority.
Option C: Logic and data are the core components of logos, making this the correct answer.
Option D: Persuasion is a broader term that encompasses logos, pathos, and ethos, but logos specifically uses logic and data.

2. What is the definition of logical?

Correct Answer: Correct answer is: (C) Sensible and based on facts.

Exam Relevance: GRE, GMAT, LSAT, SAT

Difficulty: Easy

Concept notes: In logical reasoning, a statement is considered logical if it is sensible and based on facts. Logical reasoning involves using facts and evidence to draw conclusions.

Common Mistakes: A common misunderstanding is that logical statements must be universally accepted or undisputed. However, a logical statement is simply one that is sensible and based on facts, even if it is up for debate.

Explanations: A logical statement is one that is sensible and based on facts. This means that the statement should be coherent and supported by evidence or reasoning. It does not necessarily mean that the statement is undisputed or universally accepted, but rather that it is based on a rational and factual foundation.

Option Analysis:

Option A: A statement up for argument is not necessarily logical. It could be based on opinion or subjective reasoning.
Option B: To disagree and argue against does not define logical reasoning. It describes a process of debate or disagreement.
Option C: Sensible and based on facts accurately defines logical reasoning. It emphasizes the importance of coherence and evidence.
Option D: None of the above is incorrect because option C is the correct definition of logical reasoning.

3. Joe is younger than Kathy.Mark was born after Joe.Kathy is older than Mark.If the first two statements are true then the third statement is

Correct Answer: Correct answer is: A) True.

Exam Relevance: GRE, GMAT, LSAT, CAT

Difficulty: Easy

Concept notes: The question involves logical reasoning to determine the relative ages of Joe, Kathy, and Mark based on the given statements.

Common Mistakes: A common mistake would be to assume that the third statement is false without carefully analyzing the first two statements.

Explanations: From the first statement, we know that Joe is younger than Kathy. From the second statement, we know that Mark was born after Joe, which means Mark is younger than Joe. Combining these two pieces of information, we can deduce that Mark is younger than Joe, and Joe is younger than Kathy. Therefore, Mark is younger than Kathy, which makes the third statement true.

Option Analysis:

Option A: This option is correct because the third statement logically follows from the first two statements.
Option B: This option is incorrect because the third statement is indeed true based on the given information.

Mnemonic: JMK (Joe is younger than Kathy, Mark is younger than Joe)

Concept notes: The question involves a conditional statement: if two conditions are met (going for a run and it not raining), then a specific action (wearing running shoes) should be taken. If the conditions are not met, a different action (wearing regular shoes) should be taken.

Common Mistakes: A common mistake could be misunderstanding the conditional statement and not recognizing that both conditions must be true for the action to apply.

Explanations: The scenario states that you are going for a run and it is not raining. According to the conditional statement, if both conditions are true, you should wear running shoes. Therefore, the correct action is to wear running shoes.

Option Analysis:

Option A: Correct. The conditions for wearing running shoes are met.
Option B: Incorrect. Wearing regular shoes is only appropriate if the conditions for wearing running shoes are not met.
Option C: Incorrect. The conditions are clearly defined and do not depend on other factors.

5. What is a logical inference you can make about the premises below? Jade pulled the chocolate chip cookies out of the hot oven. After looking at them for a moment, she put them back into the oven and set her timer for two more minutes.

Correct Answer: Correct answer is: (C) Jade's cookies weren't quite done baking.

Exam Relevance: GRE, GMAT, LSAT, SAT

Difficulty: Moderate

Concept notes: The question tests the ability to infer a logical conclusion from given premises.

Common Mistakes: A common mistake is to assume that the cookies are burnt or that Jade dislikes baking, without sufficient evidence from the premises.

Explanations: Jade pulled the cookies out of the oven and then put them back in for two more minutes. This action suggests that the cookies were not yet fully baked. The logical inference is that the cookies needed more time to bake properly.

Option Analysis:

Option A: This option is incorrect because there is no evidence that the cookies are burnt. Jade put them back in the oven for more time, indicating they were not overcooked.
Option B: This option is incorrect because the premise does not provide any information about Jade's feelings towards baking. The action of putting the cookies back in the oven is a normal baking process.
Option C: This option is correct because the action of putting the cookies back in the oven for more time logically implies that the cookies were not yet fully baked.
Option D: This option is incorrect because there is a logical inference that can be made from the given premises.
