Syllogism Mock Test | General Intelligence and Reasoning | SSC CGL

Q1. In a standard categorical syllogism, how many distinct propositions are typically present?

One Two Three Four

Q2. If a syllogism has two universal premises and a particular conclusion, it is said to commit the fallacy of:

Existential Import Undistributed Middle Illicit Process Begging the Question

Q3. Consider the syllogism: No mammals are fish. All whales are mammals. What is the valid conclusion?

All fish are whales. No whales are fish. Some whales are fish. No mammals are whales.

Q4. Statements: All chairs are seats. No seat is a stool. Conclusions: I. No chair is a stool. II. Some seats are chairs.

Only Conclusion I follows Only Conclusion II follows Both Conclusion I and II follow Neither Conclusion I nor II follows

Q5. The contrapositive of 'If a number is prime, then it has exactly two divisors' is:

If a number has exactly two divisors, then it is prime. If a number does not have exactly two divisors, then it is not prime. If a number is not prime, then it does not have exactly two divisors. If a number has more than two divisors, then it is not prime.

Q6. What is a potential confounding variable in a syllogistic reasoning experiment if not controlled?

Q7. Which medieval logician significantly contributed to the understanding of existential import in categorical propositions, arguing that universal propositions do not necessarily imply existence?

John Duns Scotus William of Ockham Thomas Aquinas Albert of Saxony

Q8. An AI system for qualitative physics models situations using qualitative variables (e.g., 'increasing', 'decreasing', 'zero'). If 'Quantity A is increasing' and 'If Quantity A is increasing, then Quantity B is increasing', the system concludes 'Quantity B is increasing'. This is a direct analogy to:

The syllogistic mood Ferio (EIO-1) The syllogistic mood Darii (AII-1) The syllogistic mood Baroco (AOO-2) The syllogistic mood Bocardo (OAO-3)

Q9. The cognitive process that involves building a mental representation of the entire syllogism, including the relationship between all three terms, is often referred to as:

Propositional integration Holistic representation Relational mapping Structural encoding

Q10. Consider the syllogism: All students are honest. Some honest people are rich. Therefore, some students are rich.

Valid. Invalid, undistributed middle. Invalid, illicit minor. Invalid, existential fallacy.

Q11. No employee is a manager. Some workers are employees. What is a valid deduction?

True False Indeterminate Contradictory

Q13. Which of the following is a valid syllogism form in Figure 2?

Darii Felapton Festino Bocardo

Q14. When a computational model represents syllogistic quantifiers (e.g., 'all', 'some', 'no') as probabilities or fuzzy membership functions, it is attempting to address which aspect of human reasoning?

The absolute certainty of logical deduction The probabilistic and graded nature of belief The strictly deductive application of syntax The binary true/false nature of propositions

Q15. Which of the following is a valid conclusion from 'No dogs are cats' and 'Some pets are dogs'?

All pets are dogs Some pets are not cats No pets are cats Some pets are cats

Q16. All buildings have foundations. Some houses are buildings. What is the correct inference?

All houses have foundations. Some foundations are houses. Some houses have foundations. No houses are buildings.

Q17. In a geometric progression, if the m-th term is M and the n-th term is N, what is the (m+n)-th term?

MN sqrt(MN) (M^n N^m)^(1/(m+n)) (M^n N^m)^(1/(mn))

Q18. Consider the proposition: 'Some members of parliament are not accountable.' Which of the following correctly represents its obverse?

All members of parliament are accountable. Some members of parliament are accountable. Some members of parliament are not unaccountable. Some members of parliament are unaccountable.

If the car starts, then it is not out of gas. If the car is out of gas, it will start. If the car is not out of gas, it will start. If the car will not start, then it is out of gas.

Q20. In Aristotelian logic, the conversion of an A proposition ('All S are P' to 'All P are S') is generally considered invalid unless:
