Who was drunk?

Answer:

the father

Explanation:

because when you are drunk you are not in control of yourself . thus the father murdered his son

Answer 2

Answer:

now English is a very strange language where you may find that even if one of the punctuation marks is  missing, the meaning of an entire sentence will change.

Explanation:

Like lets look at the example sentences here…. Kill him spare him not.

The sentence is simple sentence where no punctuation marks have been used. So when I read the sentence I read it as Kill him spare him not….. means that the person against whom the sentence has been spoken, should not be spared, but should be killed.

Now if I make use of punctuation mark, then I can rewrite the same sentence as Kill him, Spare him not  /  Kill him not, spare him.

Now in both cases the sentences have entire opposite meaning..as in first case it says not to spare his life, while in the second case it says not to kill him.

Same illusion or dilemma has been created in the example given by you, as no punctuation marks have been used to clarify the sentence so it is obvious a simple sentence means that the father who was drunk, murdered his son.

I hope this makes some sense now.
