Worksheet 10 of 30 (33% complete)
Question 1
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 2
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 WEAKEST (most/least strongly supported by the premises)?
The weakest conclusion is: 'All investors lost money' because Only bond investors lost money; other investments may have gained.
Question 3
Given: A school has 500 students. 60% are in sports, 40% are in music, 20% are in both activities. How many students are in neither activity?
What conclusion can be drawn?
Using set theory and logical deduction from the given numbers, '100 students are in neither activity' is the accurate conclusion.
Question 4
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 STRONGEST (most/least strongly supported by the premises)?
The strongest conclusion is: 'Exercise improves sleep quality for most people' because Large study shows clear dose-response relationship across population.
Question 5
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 6
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 7
Premises: All mammals have hair. Whales are mammals. Dolphins are mammals. Bats are mammals. Some mammals live in water. Some mammals fly.
1. Whales have hair
2. All animals with hair are mammals
3. Some flying animals are mammals
Which conclusion is the WEAKEST (most/least strongly supported by the premises)?
The weakest conclusion is: 'All animals with hair are mammals' because The premises don't state this; other animals (e.g., some reptiles) could have hair.
Question 8
Statement: No metal is transparent. Glass is transparent.
Which conclusion logically follows?
Based on the given statements, 'Glass is not metal' is the only conclusion that logically follows without making additional assumptions.
Question 9
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 STRONGEST (most/least strongly supported by the premises)?
The strongest conclusion is: 'Exercise improves sleep quality for most people' because Large study shows clear dose-response relationship across population.
Question 10
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 11
Premises: All mammals have hair. Whales are mammals. Dolphins are mammals. Bats are mammals. Some mammals live in water. Some mammals fly.
1. Whales have hair
2. All animals with hair are mammals
3. Some flying animals are mammals
Which conclusion is the WEAKEST (most/least strongly supported by the premises)?
The weakest conclusion is: 'All animals with hair are mammals' because The premises don't state this; other animals (e.g., some reptiles) could have hair.
Question 12
Given: A school has 500 students. 60% are in sports, 40% are in music, 20% are in both activities. How many students are in neither activity?
What conclusion can be drawn?
Using set theory and logical deduction from the given numbers, '100 students are in neither activity' is the accurate conclusion.
Question 13
Given: In a survey of 1000 people: 600 own cars, 400 own motorcycles, 200 own both cars and motorcycles. 100 people own neither.
What conclusion can be drawn?
Using set theory and logical deduction from the given numbers, '800 people own at least one vehicle' is the accurate conclusion.
Question 14
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.

Based only on the premises, is this statement:
Must be false — Premise says 'if raining → ground wet' with no time delay specified
Question 17
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 18
Given: Of 200 job applicants: 120 have experience, 80 have certifications, 50 have both experience and certifications. 30 have neither.
