Answer 2

Answer: E. no error.

 There is no error in the sentence "Although Sonya dances gracefully, her little brother Tomas moves moves clumsily." The subordinating conjunction "Although" introduces a contrast between the way Sonya dances, gracefully, which is an adverb, and the way her little brother moves, shown by another adverb clumsily.

Gracefully : in a smooth, relaxed, attractive way.

Clumsily : in a way that is not careful and controlled.
