Why did shakespeare noble characters speak in iambic pentameter while commoners spoke mainly in blank verse or prose ?

False.

Explanation:

Possessive pronouns are those words that tell or denote the possessive or ownership relation of the thing to the person. In other words, they indicate or tell us the relation of the thing to the persons, like telling us who owns what or what belongs to who, etc.

The use of an apostrophe in possessive cases is different, depending on the pronouns/ nouns.

An apostrophe is required when the nouns are proper nouns, like Jake's car, The old man's cane, etc.

But we require no apostrophe when using personal pronouns like his, hers, mine, yours, theirs, etc.

Thus, the correct answer is false.
