Question 1

Rule: If the store is open, lights are on Observation: The lights are off What can you logically infer?
This uses the contrapositive rule. The statement "If the store is open, lights are on" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "The lights are off" (the consequence is false), we can conclude "The store is closed" (the condition is false).

Question 2

Rule: If the store is open, lights are on Observation: The lights are off What can you logically infer?
This uses the contrapositive rule. The statement "If the store is open, lights are on" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "The lights are off" (the consequence is false), we can conclude "The store is closed" (the condition is false).

Question 3

Rule: If it's a dog, it has fur Observation: Max doesn't have fur What can you logically infer?
This uses the contrapositive rule. The statement "If it's a dog, it has fur" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "Max doesn't have fur" (the consequence is false), we can conclude "Max is not a dog" (the condition is false).

Question 4

Rule: If you're over 18, you can vote Observation: Sarah cannot vote What can you logically infer?
This uses the contrapositive rule. The statement "If you're over 18, you can vote" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "Sarah cannot vote" (the consequence is false), we can conclude "Sarah is under 18" (the condition is false).

Question 5

Rule: If it's a holiday, schools are closed Observation: The school is open What can you logically infer?
This uses the contrapositive rule. The statement "If it's a holiday, schools are closed" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "The school is open" (the consequence is false), we can conclude "It's not a holiday" (the condition is false).

Question 6

Rule: If you're over 18, you can vote Observation: Sarah cannot vote What can you logically infer?
This uses the contrapositive rule. The statement "If you're over 18, you can vote" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "Sarah cannot vote" (the consequence is false), we can conclude "Sarah is under 18" (the condition is false).

Question 7

Rule: If it's a square, it has four sides Observation: This shape doesn't have four sides What can you logically infer?
This uses the contrapositive rule. The statement "If it's a square, it has four sides" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "This shape doesn't have four sides" (the consequence is false), we can conclude "This is not a square" (the condition is false).

Question 8

Rule: If you eat sugar, your energy increases Observation: Tom's energy didn't increase What can you logically infer?
This uses the contrapositive rule. The statement "If you eat sugar, your energy increases" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "Tom's energy didn't increase" (the consequence is false), we can conclude "Tom didn't eat sugar" (the condition is false).

Question 9

Rule: If you exercise regularly, you stay healthy Observation: John is not healthy What can you logically infer?
This uses the contrapositive rule. The statement "If you exercise regularly, you stay healthy" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "John is not healthy" (the consequence is false), we can conclude "John doesn't exercise regularly" (the condition is false).

Question 10

Rule: If you eat sugar, your energy increases Observation: Tom's energy didn't increase What can you logically infer?
This uses the contrapositive rule. The statement "If you eat sugar, your energy increases" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "Tom's energy didn't increase" (the consequence is false), we can conclude "Tom didn't eat sugar" (the condition is false).

Question 11

Rule: If it's sunny, we go to the beach Observation: We didn't go to the beach What can you logically infer?
This uses the contrapositive rule. The statement "If it's sunny, we go to the beach" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "We didn't go to the beach" (the consequence is false), we can conclude "It wasn't sunny" (the condition is false).

Question 12

Rule: If it's a square, it has four sides Observation: This shape doesn't have four sides What can you logically infer?
This uses the contrapositive rule. The statement "If it's a square, it has four sides" is logically equivalent to its contrapositive: 'If NOT consequence, then NOT condition.' Since we observe "This shape doesn't have four sides" (the consequence is false), we can conclude "This is not a square" (the condition is false).
