Question 1

Statements:
1. No reptiles are mammals.
2. All snakes are reptiles.

Conclusion: No snakes are mammals.

Which of the following is true?

Accepted Answer

This tests the student's ability to apply the basic syllogistic rule: if all members of a class belong to another class, and that class is excluded from a third, then the first class is also excluded from the third.

Question 2

Statements:
1. All flowers are plants.
2. Some plants are green.

Conclusion: Either all flowers are green, or no flowers are green.

Which of the following is true?

Accepted Answer

This tests the student's ability to evaluate an 'Either/Or' conclusion against syllogistic premises. The Either/Or format is a common easy-difficulty trap where students must recognize that neither extreme conclusion is warranted.

Question 3

Statements:
1. Some athletes are disciplined.
2. All disciplined people are successful.

Conclusion: Some athletes are successful.

Which of the following is true?

Accepted Answer

This tests the student's ability to trace a valid logical path through a middle term. The middle term 'disciplined' is properly distributed, allowing a valid conclusion about the overlap between athletes and successful people.

Question 4

Statements:
1. All poets are creative.
2. No creative people are lazy.

Conclusion: No poets are lazy.

Which of the following is true?

Accepted Answer

This tests the student's ability to apply the transitive property of exclusion: if all members of one class belong to a second class, and the second class is excluded from a third, then the first class is also excluded from the third.

Question 5

Statements:
1. All teachers are educated.
2. Some educated people are doctors.

Conclusion: Some doctors are teachers.

Which of the following is true?

Accepted Answer

This is a classic syllogism testing whether students can identify invalid conclusions from valid premises. The two premises do not establish a logical link between 'doctors' and 'teachers' because 'educated people' is the middle term that appears in both premises but does not create a valid bridge.

Question 6

Statements:
1. No politician is trustworthy.
2. All judges are trustworthy.
3. Some lawyers are politicians.

Conclusions:
I. Some lawyers are not judges.
II. All judges are lawyers.

Which conclusion(s) logically follow(s)?

Accepted Answer

This tests the ability to work with negative universal premises and derive valid conclusions about overlapping categories.

Question 7

Statements:
1. All doctors are professionals.
2. No professional is unemployed.
3. Some graduates are unemployed.

Conclusions:
I. Some graduates are not professionals.
II. No doctor is unemployed.
III. Some doctors are graduates.

Which conclusion(s) must be true?

Accepted Answer

This tests the ability to work with negative universal premises and avoid invalid transitive reasoning with particular statements.

Question 8

Consider:
L ≤ M < N
N ≥ O > P
P ≤ Q = R

Which of the following is DEFINITELY FALSE?

Accepted Answer

This question requires students to identify which statement contradicts the logical chain, testing negation and careful inequality tracking.

Question 9

Statements:
1. All athletes are disciplined.
2. Some disciplined people are not successful.
3. All successful people are confident.

Conclusions:
I. Some athletes are not successful.
II. Some disciplined people are not confident.
III. Either all athletes are successful or some athletes are not successful.

Which of the following is true?

Accepted Answer

This tests the ability to distinguish between valid and invalid particular conclusions, and to evaluate either/or statements in syllogistic reasoning.

Question 10

Given the following relationships:
A > B ≥ C
D < C ≤ E
E = F > G

Which of the following conclusions is DEFINITELY TRUE?

Accepted Answer

This question tests the ability to chain inequalities correctly and identify what must be true across all possible value assignments.

Question 11

Given:
M < N ≤ O
O < P = Q
Q ≤ R < S

Which of the following is INDETERMINATE (cannot be confirmed as true or false)?

Accepted Answer

This question tests whether students can distinguish between definite conclusions and those lacking sufficient information.

Question 12

Given the following:
X ≥ Y > Z
A ≤ Z < B
B = C > D

Which conclusion is DEFINITELY TRUE?

Accepted Answer

This question tests chaining inequalities across multiple statements and identifying the one conclusion that must hold in all valid scenarios.

Question 13

Statements:
1. All teachers are educated professionals.
2. Some educated professionals are not motivators.

Conclusions:
I. Some teachers are not motivators.
II. All teachers are motivators.

Which of the following is true?

Accepted Answer

This tests the ability to distinguish between valid and invalid conclusions from mixed universal and particular premises.

Question 14

Statements:
1. All researchers are analytical.
2. No analytical people are impulsive.
3. Some employees are researchers.
4. All impulsive people are creative.

Which of the following conclusions is/are definitely true?
I. Some employees are not impulsive.
II. Some creative people are not analytical.
III. All researchers are creative.

Accepted Answer

This four-statement syllogism tests chaining across multiple premises and distinguishing valid from invalid conclusions with negations.

Question 15

Given the following relationships:
A > B ≥ C
D < C ≤ E
F = B

Which of the following conclusions is DEFINITELY TRUE?

Accepted Answer

This question tests the ability to chain inequalities and identify definite relationships while avoiding assumptions about unmeasured comparisons.

Question 16

Given:
M > N ≥ O
P < O
Q = N
R ≥ M

Which of the following is INDETERMINATE (cannot be concluded as definitely true or false)?

Accepted Answer

This question tests recognition of relationships that depend on unknown relative values, distinguishing between definite, impossible, and indeterminate conclusions.

Question 17

Consider the following:
X ≥ Y > Z
A < Z
B = Y
C ≤ X

Which of the following conclusions is DEFINITELY TRUE?

Accepted Answer

This question tests the ability to identify conclusions that must logically follow from a set of mixed inequalities and equalities, avoiding assumptions about unmeasured relationships.

Question 18

Given the following relationships:
J < K ≤ L
M ≥ L
N = K
O < J

Which of the following conclusions is DEFINITELY FALSE?

Accepted Answer

This question requires identifying a conclusion that contradicts the given constraints, testing logical negation and the ability to recognize impossible relationships.

Question 19

Given the following relationships: A > B ≥ C D < C ≤ E F = B E > A Which of the following conclusions is definitely TRUE? (A) D < B (B) F > C (C) E ≥ F (D) A = E

Accepted Answer

This is a hard inequality chaining question requiring careful transitive reasoning across multiple constraint chains.

Question 20

Statements:
1. All philosophers are critical thinkers.
2. Some critical thinkers are not logicians.
3. No logicians are poets.

Which of the following conclusions is/are definitely true?
I. Some philosophers are not logicians.
II. Some poets are not critical thinkers.
III. All critical thinkers are philosophers.

Accepted Answer

This question tests the ability to derive valid conclusions from three-statement syllogisms with mixed quantifiers and negations.
