Worksheet 10 of 10 (100% complete)

Question 1

Consider this syllogism: Premise 1: All birds can fly. Premise 2: Penguins are birds. Therefore, penguins can fly. Is this syllogism logically valid?

This is valid in form, but the premise 'All birds can fly' is false. Validity is about logical structure, not factual truth. Form: All A are B, C is A → C is B.

Question 2

Consider this syllogism: Premise 1: All cats are mammals. Premise 2: Some mammals are dogs. Therefore, some cats are dogs. Is this syllogism logically valid?

Invalid fallacy: All A are B, some B are C → does NOT imply some A are C. The some could be entirely outside A.

Question 3

Consider this syllogism: Premise 1: No reptiles are warm-blooded. Premise 2: All snakes are reptiles. Therefore, no snakes are warm-blooded. Is this syllogism logically valid?

Valid: No A are B, all C are A → No C are B.

Question 4

Consider this syllogism: Premise 1: All mammals are animals. Premise 2: All dogs are mammals. Therefore, all dogs are animals. Is this syllogism logically valid?

This is valid: If A ⊆ B and B ⊆ C, then A ⊆ C. All dogs (A) are mammals (B), all mammals (B) are animals (C), so all dogs (A) are animals (C).

Question 5

Consider this syllogism: Premise 1: No reptiles are warm-blooded. Premise 2: All snakes are reptiles. Therefore, no snakes are warm-blooded. Is this syllogism logically valid?

Valid: No A are B, all C are A → No C are B.

Question 6

Consider this syllogism: Premise 1: All mammals are animals. Premise 2: All dogs are mammals. Therefore, all dogs are animals. Is this syllogism logically valid?

This is valid: If A ⊆ B and B ⊆ C, then A ⊆ C. All dogs (A) are mammals (B), all mammals (B) are animals (C), so all dogs (A) are animals (C).

Question 7

Consider this syllogism: Premise 1: Some students are athletes. Premise 2: All athletes are healthy. Therefore, some students are healthy. Is this syllogism logically valid?

Valid: Some A are B, all B are C → Some A are C.

Question 8
