•Animals are always mortally ofended if I fail to notice them.
• The only animals that belong to me are in that eld.
•No animal can guess a conundrum unless it has been properly trained in a Board-School.
• None of the animals in that eld are badgers.
• When an animal is mortally offended, it rushes about wildly and howls.
• I never notice any animal unless it belongs to me.
• No animal that has been properly trained in a Board-School ever rushes about wildly and howls. What can you conclude from these statements? Justify your answer. (Hint: Model your solution after the examples on G. N. Hile’s website.
BASICALLY WE NEED TO USE IMPLIES (ARROW) TO CONNECT ALL STATEMENTS
Explanation / Answer
Animals are always mortally ofended if I fail to notice them. I never notice any animal unless it belongs to me.
THESE TWO STATEMETS FROM ABOVE TELL THAT LEWIS DOES NOT OFFEND HIS ANIMALS IN ANY CASE.
The only animals that belong to me are in that eld. None of the animals in that eld are badgers.
THESE TWO STATEMENTS TELL THAT LEWIS OWN SOME ANIMALS AND THOSE ANIMALS ARE PRESENT IN THE FIELD AND THOSE ANIMALS ARE NOT BADGERS
No animal can guess a conundrum unless it has been properly trained in a Board-School. When an animal is mortally offended, it rushes about wildly and howls. No animal that has been properly trained in a Board-School ever rushes about wildly and howls
THESE THREE STATEMENTS TELL ABOUT THE BEHAVIOUR OF THE TRAINED ANIMAL AND THE UNTRAINED ANIMAL WHEN BEING OFFENDED BUT LEWIS DOES NOT TELL WHETER HIS ANIMALS WERE TRAINED OR NOT.
