Sample CHSE Odisha Elective Logic Practice Questions

Try these sample questions to review concepts for the CHSE Odisha Elective Logic exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In the CHSE +2 Logic syllabus, logic is best defined as the science of:
A.Correct reasoning and valid inference from premises to conclusions
B.Only memorising famous philosophers' biographies
C.Only measuring physical quantities with instruments
D.Only writing creative fiction without evidence
Explanation: Logic studies the principles of correct reasoning—how conclusions follow validly from premises—not biography, physics measurement, or fiction writing.
2In an argument, the statements offered as reasons for accepting a claim are called:
A.Conclusions only
B.Premises
C.Fallacies only
D.Hypotheses only
Explanation: Premises are the supporting statements from which a conclusion is drawn; structure of argument is a core Year-1 unit topic.
3Which distinction is fundamental in logic?
A.Only verb tense versus adjective colour
B.Only poem versus novel
C.Sentence (grammatical unit) versus proposition (truth-bearing claim)
D.Only integer versus fraction in arithmetic alone
Explanation: The syllabus distinguishes sentences (linguistic expressions) from propositions (declarative contents that are true or false).
4Truth applies primarily to which of the following?
A.Arguments as a whole in place of validity
B.Only the physical shape of printed letters
C.Only the length of a written paragraph
D.Propositions (or statements that assert something)
Explanation: Truth and falsity are properties of propositions; validity is a property of arguments. Confusing the two is a classic exam trap.
5An argument is valid when:
A.If the premises are true, the conclusion must be true (the form preserves truth)
B.The conclusion is popular with many people
C.The premises are written in long sentences
D.The speaker has a high social status
Explanation: Validity is formal: true premises guarantee a true conclusion. Popularity, length, and status are irrelevant to validity.
6A sound argument is one that is:
A.Invalid but persuasive in advertising
B.Valid and has all true premises
C.Valid with at least one false premise only
D.A mere collection of unrelated questions
Explanation: Soundness = validity + true premises. An unsound argument fails either validity or truth of premises (or both).
7Which of the following best illustrates an unsound but valid argument?
A.Any set of true premises with a true conclusion, regardless of form
B.A random list of adjectives with no inference
C.All fish are mammals. All mammals breathe air with lungs only. Therefore all fish breathe air with lungs only. (valid form, false premises)
D.A single true proposition with no premises and no conclusion relation
Explanation: The form can be valid (if premises true, conclusion must be) while premises are factually false—hence valid but unsound.
8The traditional principles of thought often associated with classical logic include the laws of:
A.Only supply and demand
B.Only gravity and inertia
C.Only rhyme and metre
D.Identity, non-contradiction, and excluded middle
Explanation: Principles of logic in the syllabus framework include identity (A is A), non-contradiction (not both A and not-A), and excluded middle (A or not-A).
9In logic and language, denotation of a term primarily refers to:
A.The class of objects to which the term applies (extension)
B.Only the emotional tone of a poem
C.Only the ink colour used to print the word
D.Only the number of syllables in the word
Explanation: Denotation (extension) is the set of things a term applies to; connotation (intension) is the attributes the term implies.
10Connotation of a term is best described as:
A.Only the alphabetical order of letters
B.The attributes or qualities the term implies (intension)
C.Only the geographic origin of the speaker
D.Only the font size of the printed term
Explanation: Connotation (intension) comprises defining attributes; it contrasts with denotation/extension of objects covered.
