Fill in the blank with the correct word.

Question

1.Regardless of what others say,I would
advise you to_________ to George's
judgement.
(defer,differ)

2.All things considered_______ not a
bad day,since morale is excellent.
(it's, its)

The apostrophe means it's is a contraction for it is.

I know it's is an apostrophe for it is.
But would I use it's (it is or its) in the sentence,because both would be correct,but,I can only use one of the words.

Its is the possessive.
It's is a contraction for it is.
It's (it is) time to go home.
I kicked its head. (Does it make sense to say "I kicked it's head"?)
