Worksheet 9 of 30 (30% complete)

Question 1

Statement: She must be intelligent since she graduated from Harvard. Evaluate this assumption: 'Harvard only admits intelligent students' Is this assumption valid?
Questionable - intelligence has multiple factors
assumption, validity, evaluation

Question 2

Statement: Public transportation reduces traffic congestion in major cities. Which of the following is an assumption made in the statement?
The statement assumes that people will use public transportation, which is necessary for the argument to be valid.
assumption, identification, basic

Question 3

Argument: If you want to lose weight, you should exercise regularly. However, exercise alone isn't enough; you also need a healthy diet. Assumption: 'Exercise and diet together are sufficient for weight loss' Is this assumption necessary, sufficient, both, or neither for the argument's conclusion?
Sufficient: The argument implies that doing both will achieve weight loss
assumption, necessary, sufficient, logic

Question 4

Statement: Students perform better when class sizes are reduced from 30 to 15 students. What is the primary assumption underlying this statement?
The statement implicitly assumes that teacher attention improves with fewer students, which is crucial for the conclusion to be valid.
assumption, implicit, analysis

Question 5

Statement: The city should ban private vehicles during weekdays and promote electric buses to reduce air pollution and improve public health. Which assumption is most fundamental to this argument?
While the statement makes multiple assumptions, 'Private vehicles are major pollution sources' is the most fundamental because without it, the entire premise of the solution becomes questionable.
assumption, multiple, complex

Question 6

Statement: Online education is becoming more popular than traditional classroom learning. Which of the following is an assumption made in the statement?
The statement assumes that traditional education has limitations, which is necessary for the argument to be valid.
assumption, identification, basic

Question 7

Argument: To get an A in this course, you must complete all assignments and score above 90% on the final exam. Assumption: 'Scoring above 90% on the final exam is necessary for an A' Is this assumption necessary, sufficient, both, or neither for the argument's conclusion?
Necessary: Also explicitly required by the statement
assumption, necessary, sufficient, logic

Question 8

Statement: The stock market rose today, indicating economic recovery is underway. What hidden premise must be true for this argument to be valid?
The argument implicitly assumes that stock market performance reflects overall economic health, which may not always be true.
assumption, premise, hidden

Question 9

Statement: Crime rates decreased after installing more street lights, proving that better lighting reduces crime. Which assumption is most problematic in this causal argument?
The assumption 'Correlation implies causation' is problematic because it establishes causation without ruling out alternative explanations or confounding variables.
assumption, causality, logic

Question 10

Argument: We should hire Maria as our lead developer because she has 10 years of experience in our industry. Consider the assumption: 'No other candidate has more relevant experience' If we negate this assumption (assume the opposite), does it break the argument?
Yes — If others have more experience, she may not be the best choice

Negation test: If 'Other candidates have more relevant experience' then the argument 'fails'.
assumption, negation, test, validity

Question 11

Statement: Since it rained yesterday, the cricket match must have been cancelled. Evaluate this assumption: 'Rain always leads to cricket match cancellation' Is this assumption valid?
Invalid - matches can continue in light rain
assumption, validity, evaluation

Question 12

Statement: The restaurant is expensive because it's located in the city center. Evaluate this assumption: 'City center locations have higher operational costs' Is this assumption valid?
Valid - location affects rent and operational expenses
assumption, validity, evaluation

Question 13

Statement: Students perform better when class sizes are reduced from 30 to 15 students. What is the primary assumption underlying this statement?
The statement implicitly assumes that teacher attention improves with fewer students, which is crucial for the conclusion to be valid.
assumption, implicit, analysis

Question 14

Argument: To get an A in this course, you must complete all assignments and score above 90% on the final exam. Assumption: 'Completing all assignments guarantees an A' Is this assumption necessary, sufficient, both, or neither for the argument's conclusion?
Not necessarily true: You also need the exam score - assignments alone are insufficient
assumption, necessary, sufficient, logic

Question 15

Statement: The new drug should be approved for public use since clinical trials showed 95% effectiveness. What is the primary assumption underlying this statement?
The statement implicitly assumes that clinical trials represent real-world conditions, which is crucial for the conclusion to be valid.
assumption, implicit, analysis

Question 16

Statement: This candidate has 20 years of experience, so they're the best choice for the position. What hidden premise must be true for this argument to be valid?
The argument implicitly assumes that experience duration directly correlates with job performance, which may not always be true.
assumption, premise, hidden

Question 17

Statement: She must be intelligent since she graduated from Harvard. Evaluate this assumption: 'Harvard only admits intelligent students' Is this assumption valid?
Questionable - intelligence has multiple factors
assumption, validity, evaluation

Question 18

Statement: The stock market rose today, indicating economic recovery is underway. What hidden premise must be true for this argument to be valid?
The argument implicitly assumes that stock market performance reflects overall economic health, which may not always be true.
assumption, premise, hidden

Question 19

Argument: The new traffic light at Main Street will reduce accidents because it will control the previously dangerous intersection. Consider the assumption: 'Drivers will obey the traffic light' If we negate this assumption (assume the opposite), does it break the argument?
Yes — If drivers ignore it, the light won't reduce accidents

Negation test: If 'Drivers will NOT obey the traffic light' then the argument 'fails'.
assumption, negation, test, validity

Question 20

Argument: To get an A in this course, you must complete all assignments and score above 90% on the final exam. Assumption: 'Completing assignments AND scoring above 90% is sufficient for an A' Is this assumption necessary, sufficient, both, or neither for the argument's conclusion?
Sufficient: The statement implies that meeting both conditions results in an A
assumption, necessary, sufficient, logic
