Hurry hurry hurry! What's wrong with the following sentence:
I could of sworn I past you on the street yesterday.
(P. S I've already worked out that past should be passed but I am not sure what else. I think the "of" should be "the". Im\'m just checking! Thanks!)

It's "I could have sworn I passed you on the street yesterday"

Explanation:

This is just the correct way to write this sentence sorry if it's wrong!

well if you have a lion for example it will kill you and that's why you shouldn't have and exotic animal

the type of supporting detail is fact!
