9. "Every bear I've seen had black fur. Therefore, most bears probably have black fur."

Correct Answer: Correct answer is: (A) This is an inductive reasoning.

Exam Relevance: GRE, GMAT, LSAT, MCAT

Difficulty: Moderate

Concept notes: Inductive reasoning involves making broad generalizations from specific observations. Deductive reasoning, on the other hand, involves drawing specific conclusions from general principles.

Common Mistakes: A common misunderstanding is confusing inductive reasoning with deductive reasoning. Deductive reasoning starts with a general statement and reaches a specific conclusion, while inductive reasoning starts with specific observations and reaches a general conclusion.

Explanations: The statement "Every bear I've seen had black fur. Therefore, most bears probably have black fur" is an example of inductive reasoning. The reasoning starts with specific observations (every bear seen had black fur) and makes a generalization (most bears probably have black fur). This is characteristic of inductive reasoning, where specific instances are used to infer a broader conclusion.

Option Analysis:

Option A: This is correct because the reasoning is based on specific observations leading to a general conclusion, which is the essence of inductive reasoning.
Option B: This is incorrect because deductive reasoning would involve starting with a general principle and reaching a specific conclusion, which is not the case here.

10. "Never to accept anything for true till all grounds of doubt are excluded "is one of the rules laid by Rene descartes in his book ..... which is supposed to have a great impact on the scientific method of research

Correct Answer: Correct answer is: (B) Discourse on the method.

Exam Relevance: GRE, GMAT, Philosophy exams, History of Science exams

Difficulty: Moderate

Concept notes: Rene Descartes laid out his methodological principles in "Discourse on the Method," which had a significant impact on the development of the scientific method.

Common Mistakes: A common mistake is confusing "Discourse on the Method" with other philosophical works by Descartes or other authors.

Explanations: Rene Descartes outlined his methodological principles in "Discourse on the Method," which includes the rule of never accepting anything as true until all grounds of doubt are excluded. This rule is foundational to the scientific method, emphasizing the importance of rigorous doubt and verification.

Option Analysis:

Option A: "The Histories" is a work by Herodotus, not Descartes.
Option B: "Discourse on the Method" is the correct work where Descartes laid out his methodological principles.
Option C: "Reason in History" is not a work by Descartes.
Option D: "The Capital" is a work by Karl Marx, not Descartes.
