Based only on the premises, is this statement:
Must be true — Lazy people are unhappy, but they aren't researchers; they could be doctors or not
Question 3
Premises: All books in this library are catalogued. Some catalogued items are digital. All digital items are searchable.
Which conclusion can be drawn with certainty?
Following the logical chain from the premises, 'Some books are searchable' is the only conclusion that can be drawn with certainty.
Question 4
Statements: All cats are independent. Some cats are very social and need constant companionship. Fluffy is a cat who loves being around people all the time.
What can be concluded?
The statements present contradictory information, making 'The statements contain contradictory information' the most logical conclusion.
Question 5
Premises: In a study of 10,000 people, 95% who exercised daily reported better sleep. 80% who exercised 3-4 times weekly reported better sleep. 30% who exercised rarely reported better sleep. Sarah exercises 5 times per week.
1. Sarah definitely has better sleep than someone who never exercises
2. Sarah is more likely to have better sleep than the average person
3. Exercise improves sleep quality for most people
Which conclusion is the WEAKEST (most/least strongly supported by the premises)?
The weakest conclusion is: 'Sarah definitely has better sleep than someone who never exercises' because Correlation doesn't guarantee individual outcomes; individual variation exists.
Question 6
Premises: All students who passed the exam studied at least 10 hours. John studied 15 hours. Mary studied 5 hours. Sarah studied 10 hours exactly.
Statement: Mary definitely failed
Based only on the premises, is this statement:
Must be true — Premise says ALL who passed studied ≥10 hours. Mary studied 5 hours, so she cannot have passed
Question 7
Premises: All managers are leaders. Some leaders are innovative. No innovative person is conservative.
Which conclusion can be drawn with certainty?
Following the logical chain from the premises, 'Some managers are not conservative' is the only conclusion that can be drawn with certainty.
Question 8
Statement: All students in this class passed the exam. John is in this class.
Which conclusion logically follows?
Based on the given statements, 'John passed the exam' is the only conclusion that logically follows without making additional assumptions.
Question 9
Premises: All books in this library are catalogued. Some catalogued items are digital. All digital items are searchable.
Which conclusion can be drawn with certainty?
Following the logical chain from the premises, 'Some books are searchable' is the only conclusion that can be drawn with certainty.
Question 10
Statements: All cats are independent. Some cats are very social and need constant companionship. Fluffy is a cat who loves being around people all the time.
What can be concluded?
The statements present contradictory information, making 'The statements contain contradictory information' the most logical conclusion.
Question 11
Statement: 90% of students who attend all classes pass the exam. Sarah attended all classes.
What is the most reasonable conclusion?
Given the probabilistic nature of the statement, 'Sarah will likely pass the exam' is the most reasonable conclusion without overstating certainty.
Question 12
Premises: In a study of 10,000 people, 95% who exercised daily reported better sleep. 80% who exercised 3-4 times weekly reported better sleep. 30% who exercised rarely reported better sleep. Sarah exercises 5 times per week.
1. Sarah definitely has better sleep than someone who never exercises
2. Sarah is more likely to have better sleep than the average person
3. Exercise improves sleep quality for most people
Which conclusion is the WEAKEST (most/least strongly supported by the premises)?
The weakest conclusion is: 'Sarah definitely has better sleep than someone who never exercises' because Correlation doesn't guarantee individual outcomes; individual variation exists.
Question 13
Premises: If interest rates rise, bond prices fall. If bond prices fall, investors lose money. The Federal Reserve announced a rate hike yesterday. Bond prices dropped 5% today.

Question 14
Given: Of 200 job applicants: 120 have experience, 80 have certifications, 50 have both experience and certifications. 30 have neither.

Using set theory and logical deduction from the given numbers, '170 applicants have at least one qualification' is the accurate conclusion.
Question 15
Statement: Some doctors are researchers. All researchers publish papers.
Which conclusion logically follows?
Based on the given statements, 'Some doctors publish papers' is the only conclusion that logically follows without making additional assumptions.
Question 16
Premises: If interest rates rise, bond prices fall. If bond prices fall, investors lose money. The Federal Reserve announced a rate hike yesterday. Bond prices dropped 5% today.
1. The rate hike caused bond prices to drop
2. Some investors lost money today
3. All investors lost money
Which conclusion is the STRONGEST (most/least strongly supported by the premises)?
The strongest conclusion is: 'Some investors lost money today' because Directly follows: bond prices dropped 5%, so bond investors lost value.
Question 17
Statement: If unemployment rises, consumer spending decreases. If consumer spending decreases, GDP growth slows. If GDP growth slows, government revenue falls. Unemployment has increased significantly.
What can be concluded?
Following the chain of conditional logic (if-then statements), 'Government revenue will fall' is the logical conclusion.
Question 18
Statement: Some doctors are researchers. All researchers publish papers.
Which conclusion logically follows?
Based on the given statements, 'Some doctors publish papers' is the only conclusion that logically follows without making additional assumptions.
Question 19
Statement: Some doctors are researchers. All researchers publish papers.
Which conclusion logically follows?
Based on the given statements, 'Some doctors publish papers' is the only conclusion that logically follows without making additional assumptions.
Question 20
Premises: All managers are leaders. Some leaders are innovative. No innovative person is conservative.
Which conclusion can be drawn with certainty?
Following the logical chain from the premises, 'Some managers are not conservative' is the only conclusion that can be drawn with certainty.
