15
Question
What are the three characteristics of critical thinking?

16
Question
Describe the analytical skill needed for critical thinking.
Page 7
Answer

17
Question
What is the interpretative skill in critical thinking?
Page 7
Answer
Enables understanding situations, explaining meanings and relevance clearly, dissecting complexities into simple terms.
18
Question
How is an inference defined in critical thinking?
Page 7
Answer
Process of drawing a conclusion from an argument, usually from evidence or information. Must be sound or safe.
19
Question
What distinguishes evaluative skill in logic arguments?
Page 8
Answer
Assesses credibility, relevance, strength, validity; detects assumptions, biases, fallacies in inductive arguments.
20
Question
Why do good arguments need explanative skill?
Page 8
Answer
Provide sufficient explanation of reasons/evidence with coherent logical relationship to conclusion; lack leads to weak arguments.
21
Question
What is problem-solving skill's role in critical thinking?
Page 8
Answer
Identifies problems, determines pathways to solve; uses strategies systematic or trial-error, heart of critical thinking.
22
Question

Improves reasoning skills; learns techniques of reasoning, making/evaluating arguments, constructing logical proofs.
24
Question
What second reason makes studying logic significant?
Page 9

25
Question
