Answer this if you can?

Question

if all cats are dogs and all dogs are birds, then all cats are definetely birds! u think this sentence is logically true?

Answer 1

Yes, definitely. Think of this in other terms. Instead of cats, use "men," instead of dogs use "humans," and instead of birds, use "thinking beings."

After you substitute the words, you get the following statement, which is logically true.

If all men are humans, and all humans are thinking beings, then all men are thinking beings.

NOTE: A example does not prove a statement, but I am giving this example to show the logic being used.

Notice that you couldn't have concluded that all birds are cats because it would be the equivalent as saying

"all thinking beings are men" which is false.

I hope this helps.

Now, for those of you who say "NO because birds cannot be cats etc. etc." Your statement is false. This is because the statement in the question starts with "IF."

Answer 2

yes it is definetely (logically) a true sentence..if all cats are dogs and all dogs are birds then all cats are birds..it make sense..good one ;)

Answer 3

I can tell you how it can definetely be true. If all cats are definetely not birds, then all cats are not dogs and all dogs are not birds.

Answer 4

Yes it is logically a true sentence to me

Answer 5

No if cats are dogs there not birds cuz dogs are birds and you cant have dogs and cats being birds .. so cats have to be something els

Answer 6

Yes this OMG sentence is OMG logically true

Answer 7

Yes.

Your two statements are:

All C are a subset of D
All D are a subset of B

Therefore, your conclusion should be axiomatically:

All C are a subset of B.

However, the converse is not true:

All B are NOT a subset of C

Of course, I'm guessing your just screwing around and you don't know the first thing about formal logic at all...

Answer 8

no because cats eat birds and cats do not have wings or two feet so nope.
