i think it might be the fourth one?
<span>What the Chorus Leader assumes to be the reason for Antigone's decision to go against her king is that she is Oedipus' daughter and she can't help herself because of bitterness. She decided to disobey Creon's orders and wanted to give her brother a proper burial even though he is a traitor to the state. The king didn't want him to be buried, but rather to be left to the dogs to eat him, however, Antigone never wanted to let that happen.</span>
Answer: LADY MACBETH
Explanation: in Act 5 Scene 1
"Out, d****ed spot! Out, I say!—One, two. Why, then, ’tis time to do ’t. H*ll is murky!—Fie, my lord, fie! A soldier, and afeard? What need we fear who knows it, when none can call our power to account?—Yet who would have thought the old man to have had so much blood in him."
You use "it's" as a formal Contraction, it's short for 'it is' or 'it has'.
For example, 'it's a wonderful day's
You use "so" when you are describing something
For example, 'it's so hot'
"So" is also another word for "very", which is where the word originally generated. it's often mixed up with "such", but dont worry! you'll learn English alot soon!
