Statement: Students perform better when class sizes are reduced from 30 to 15 students. What is the primary assumption underlying this statement?

The argument implicitly assumes that safety is the primary criterion for energy policy decisions, which may not always be true.
assumption, premise, hidden

Question 4

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 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: The government should increase minimum wage to help reduce poverty. Which of the following is an assumption made in the statement?
The statement assumes that businesses can afford higher wages, which is necessary for the argument to be valid.
assumption, identification, basic

Question 7

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 8

Statement: Nuclear energy is safer than coal power, therefore we should build more nuclear plants. What hidden premise must be true for this argument to be valid?
The argument implicitly assumes that safety is the primary criterion for energy policy decisions, which may not always be true.
assumption, premise, hidden

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: 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 13

Statement: The government should increase minimum wage to help reduce poverty. Which of the following is an assumption made in the statement?
The statement assumes that businesses can afford higher wages, which is necessary for the argument to be valid.

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: 'Anyone over 35 can be president' Is this assumption necessary, sufficient, both, or neither for the argument's conclusion?
False: Ignores citizenship and residency requirements
assumption, necessary, sufficient, logic

Question 16

Argument: This new medicine should be approved because clinical trials show it's effective for 85% of patients. Consider the assumption: 'Side effects are acceptable' If we negate this assumption (assume the opposite), does it break the argument?
Yes — Unacceptable side effects would block approval regardless of efficacy

Negation test: If 'Side effects are NOT acceptable' then the argument 'fails'.
assumption, negation, test, validity

Question 17

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.

Statement: Students' test scores improved after the new teaching method was introduced, confirming its effectiveness. Which assumption is most problematic in this causal argument?
