IDAT Critical Thinking and Analysis 3 — Questions and Answers
Question 1: A politician says: 'We must either increase taxes or cut education funding.' A critical thinker would first question whether:
- These are truly the only two options available (Correct answer)
- Taxes have been increased before
- Education funding is currently sufficient
- The politician has a conflict of interest
Correct answer: These are truly the only two options available
This is a false dilemma — it presents only two options when other alternatives likely exist.
Question 2: In an argument, which element provides direct support for the conclusion?
- Premise (Correct answer)
- Inference
- Counterargument
- Assumption
Correct answer: Premise
Premises are the stated reasons or evidence offered in support of the conclusion.
Question 3: A news headline reads: 'Scientists say coffee may reduce risk of heart disease.' What does the word 'may' most significantly indicate about this claim?
- The evidence is tentative and not conclusive (Correct answer)
- The claim has been proven false
- Only certain types of coffee are beneficial
- The study was conducted on animals, not humans
Correct answer: The evidence is tentative and not conclusive
Hedging language like 'may' signals that findings are preliminary or probabilistic, not definitive.
Question 4: Which of the following is the strongest evidence to support the claim that a new drug reduces fever?
- A randomized controlled trial with a large placebo group showing statistically significant fever reduction (Correct answer)
- Testimonials from 50 patients who say the drug worked for them
- A doctor's statement that the drug is effective based on personal experience
- A company-funded study showing 80% of users felt better
Correct answer: A randomized controlled trial with a large placebo group showing statistically significant fever reduction
Randomized controlled trials with placebo groups are the gold standard for establishing causal medical claims.
Question 5: The phrase 'slippery slope' in argumentation refers to:
- Claiming one event will inevitably lead to a chain of extreme consequences without adequate justification (Correct answer)
- Providing too many supporting examples for a single claim
- Changing the subject when confronted with a strong counterargument
- Using emotional language to bypass logical reasoning
Correct answer: Claiming one event will inevitably lead to a chain of extreme consequences without adequate justification
A slippery slope fallacy assumes a series of increasingly negative outcomes from one action without evidence each step follows.
Question 6: When analyzing an argument, distinguishing between a fact and an opinion is important primarily because:
- Facts can be verified objectively while opinions reflect personal judgment (Correct answer)
- Opinions are always less important than facts
- Facts do not require evidence but opinions do
- Opinions can never support a valid argument
Correct answer: Facts can be verified objectively while opinions reflect personal judgment
Facts are empirically verifiable claims; opinions express values or preferences and require different evaluation standards.
Question 7: A report notes that neighborhoods with more streetlights have lower crime rates. A mayor uses this to propose installing more streetlights to reduce crime. The weakest point in this reasoning is:
- Assuming streetlights cause lower crime rather than both being caused by higher municipal investment (Correct answer)
- Claiming crime rates can be measured accurately
- Suggesting that streetlights are affordable to install
- Implying all neighborhoods have the same crime types
Correct answer: Assuming streetlights cause lower crime rather than both being caused by higher municipal investment
Both streetlights and low crime could be effects of wealthier, more invested neighborhoods rather than one causing the other.
