Worksheet 30 of 30 (100% complete)

Question 1

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 2

Argument: The new traffic light at Main Street will reduce accidents because it will control the previously dangerous intersection. Consider the assumption: 'The light will be properly maintained' If we negate this assumption (assume the opposite), does it break the argument?
Yes — A malfunctioning light could increase accidents

Negation test: If 'The light will NOT be properly maintained' then the argument 'fails'.
assumption, negation, test, validity

Question 3

Argument: We should hire Maria as our lead developer because she has 10 years of experience in our industry. Consider the assumption: 'Industry experience is relevant to job performance' If we negate this assumption (assume the opposite), does it break the argument?
Yes — If experience isn't relevant, then her 10 years don't justify hiring her

Negation test: If 'Industry experience is NOT relevant to job performance' then the argument 'fails'.
assumption, negation, test, validity

Question 4

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

Question 5

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 6

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 7

Argument: The new traffic light at Main Street will reduce accidents because it will control the previously dangerous intersection. Consider the assumption: 'The light will be properly maintained' If we negate this assumption (assume the opposite), does it break the argument?
Yes — A malfunctioning light could increase accidents

Negation test: If 'The light will NOT be properly maintained' then the argument 'fails'.
assumption, negation, test, validity

Question 8

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

Question 9

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 10

Statement: Students' test scores improved after the new teaching method was introduced, confirming its effectiveness. Which assumption is most problematic in this causal argument?
The assumption 'The teaching method caused the improvement' is problematic because it establishes causation without ruling out alternative explanations or confounding variables.
assumption, causality, logic

Question 11

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 12

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 13

Statement: Students' test scores improved after the new teaching method was introduced, confirming its effectiveness. Which assumption is most problematic in this causal argument?
The assumption 'The teaching method caused the improvement' is problematic because it establishes causation without ruling out alternative explanations or confounding variables.
assumption, causality, logic

Question 14

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 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

Argument: To be president of the United States, a person must be at least 35 years old, a natural-born citizen, and a resident for 14 years. Assumption: 'Being a natural-born citizen is necessary' Is this assumption necessary, sufficient, both, or neither for the argument's conclusion?
Necessary: Constitutional requirement
assumption, necessary, sufficient, logic

Question 17
