The correct choice that compares and contrasts the styles of the claims is:
Claim 1 has a formal style with advanced vocabulary and complex syntax. Claim 2 has an informal style, addressing the audience as you and using contractions.
This choice accurately reflects the formal tone of Claim 1, which presents factual information in a more structured and sophisticated manner, while Claim 2 adopts a casual tone that directly addresses the reader and uses informal language.
