1In inductive logic as taught in Karnataka II PUC, induction is primarily the process of reasoning from:
A.A general rule to a particular instance only
B.Symbols to truth tables
C.Particular instances to a general conclusion
D.Definitions to their synonyms
Explanation: Induction proceeds from observed particular cases (or a limited set of instances) to a more general conclusion. The conclusion is broader than the premises and is therefore probable rather than certain in imperfect induction. This is the core contrast with deduction, which typically applies general principles to particular cases.
2What is the key formal difference between a typical deductive conclusion and a typical inductive conclusion?
A.Deductive conclusions claim necessity from the premises; inductive conclusions claim only probability
B.Induction is only about mathematics; deduction is only about science
C.Inductive conclusions are always certain; deductive conclusions are always uncertain
D.Deduction never uses premises; induction always uses axioms
Explanation: In valid deduction, if the premises are true the conclusion must be true (necessity of the formal link). In imperfect induction, even true supporting premises leave a logical gap—the inductive leap—so the conclusion is only probable. II PUC Logic builds on this contrast throughout the inductive syllabus.
3‘Perfect induction’ (complete enumeration) differs from imperfect induction because perfect induction:
A.Never examines any particular cases
B.Is identical to Mill’s Method of Residues
C.Examines all members of a limited class before generalizing
D.Always yields only a probable conclusion about infinite classes
Explanation: Perfect induction enumerates every member of a finite, fully surveyed class and then states a generalisation that simply summarises those cases. Because the class is completely examined, the generalisation does not go beyond the evidence in the way imperfect induction does. Imperfect induction generalises from a sample to unexamined cases.
4Induction by simple enumeration typically generalises from:
A.A purely mathematical definition
B.A series of observed instances without experimental isolation of causes
C.A single controlled laboratory experiment only
D.A formal syllogism in Barbara
Explanation: Simple enumeration notes that many observed A’s have been B and concludes that all (or most) A’s are B. It does not systematically vary conditions to isolate causes the way scientific induction and Mill’s methods attempt to do. Its probability rises with number and variety of instances but remains vulnerable to counter-examples.
5The ‘inductive leap’ refers to:
A.The logical gap between observed instances and the unexamined cases covered by the generalisation
B.Converting an A proposition to an E proposition
C.Replacing a middle term in a syllogism
D.Jumping from a conclusion back to its premises in deduction
Explanation: In imperfect induction, premises report only some observed cases, while the conclusion claims something about a wider class (including unobserved cases). The step across that gap is the inductive leap. It is why inductive support is a matter of degree of probability rather than formal necessity.
6Scientific induction, as contrasted with mere simple enumeration in II PUC Logic, emphasises:
A.Rejecting all observation in favour of pure definition
B.Proving conclusions with the same necessity as valid syllogisms
C.Using only one instance ever
D.Causal analysis and systematic investigation of conditions, not only counting favourable instances
Explanation: Scientific induction seeks higher probability by analysing causes and conditions (often with experiment and Mill’s methods), rather than merely tallying similar observations. It still yields probable conclusions, but the evidential base is stronger than simple enumeration alone.
7Which statement best characterises the conclusion of imperfect induction?
A.It is formally necessary if any one premise is true
B.It goes beyond the evidence and is therefore only probable
C.It is always false
D.It cannot be revised when new instances appear
Explanation: Imperfect induction asserts more than the premises strictly guarantee. New counter-examples or better evidence can raise or lower the probability of the conclusion. That revisability is a hallmark of inductive science.
8‘All observed crows are black; therefore all crows are black’ is an example of:
A.Perfect induction of an infinite class
B.Imperfect induction by simple enumeration
C.A valid categorical syllogism in Celarent
D.A purely analytic definition
Explanation: The premise reports only observed crows; the conclusion covers all crows, including unobserved ones. That is classic simple enumeration / imperfect induction. It is not a syllogism with a middle term linking two categorical premises, nor a complete enumeration of every crow.
9Why can a valid inductive argument still have a false conclusion even when its premises are true?
A.Because all inductive conclusions are definitions
B.Because induction is identical to formal contradiction
C.Because induction amplifies beyond the evidence and leaves room for unexamined counter-instances
D.Because induction forbids using any true premises
Explanation: Amplification is built into imperfect induction: the conclusion says more than the premises strictly contain. True observational premises can coexist with an unknown counter-example, so a false generalisation remains possible. That possibility is expressed as less-than-certainty (probability).
10Which of the following is a legitimate use of induction in scientific inquiry?
A.Drawing Euler diagrams for A, E, I, O propositions only
B.Forming and testing generalisations about natural regularities from observed cases
C.Defining ‘bachelor’ as ‘unmarried man’
D.Proving that a valid syllogism’s conclusion must follow by form alone
Explanation: Science depends on inductive generalisation and causal inference from observation and experiment. Syllogistic necessity, analytic definitions, and Euler diagrams belong primarily to deductive/propositional foundations treated more fully in I PUC Deductive Logic.

About the Karnataka II PUC Logic (KSEAB) Exam

Karnataka II PUC Logic is the Class 12 Pre-University public examination Logic paper (subject code 23) under the Karnataka School Examination and Assessment Board (KSEAB). While I PUC Logic develops Deductive Logic (propositions, opposition, syllogism, symbolic logic, and introductory Indian logic), II PUC focuses on Inductive Logic and scientific method: Nature of Induction; Postulates/Grounds of Induction; Concept of Cause; J.S. Mill’s five experimental methods; Scientific Method and Hypothesis; Probability; Scientific Explanation; Material Fallacies; and Indian Logic (Nyaya inference and related concepts). The official assessment is a mixed objective + subjective paper lasting about 3 hours. Fees and exact blueprints are notified by KSEAB on kseab.karnataka.gov.in and the DPUE blueprint portal; pass marks are commonly described as about 30% per subject with ~33% aggregate. The 100 questions on this page are a free English-language multiple-choice study adaptation; they are not a full simulation of the official mixed paper.

Exam sponsor: Karnataka School Examination and Assessment Board (KSEAB). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Official KSEAB II PUC Logic (subject code 23) is assessed as a mixed paper: objective-style items plus multi-mark short and long answers on Inductive Logic, lasting about 3 hours for many II PUC sittings.

Syllabus chapters: Nature of Induction; Postulates/Grounds of Induction; Concept of Cause; J.S. Mill’s Experimental Methods; Scientific Method and Hypothesis; Probability; Scientific Explanation; Material Fallacies; Indian Logic. This practice bank is an English-language MCQ study adaptation for concept fluency — it does not simulate official attempt limits, long answers, or internal assessment.

Karnataka II PUC Logic (KSEAB): Suggested Study Strategy

1Memorize the canons of Mill’s five methods and practise one original example for each method.
2Distinguish formal grounds (uniformity of nature; causation) from material grounds (observation; experiment) of induction.
3Build a fallacy cheat sheet: false cause, hasty generalization, composition/division, begging the question, and the main argumentum fallacies.
4For Indian Logic, master Nyaya’s four pramanas, the five avayavas of pararthanumana, and common hetvabhasas.
5After MCQ concept checks, write full short and long answers from KSEAB Logic model papers under timed conditions.
