Answer 1

The answer to your question would be that the sentence that combines the two sentences with an appositive phrase is the following one: In 1903, two brothers, Orville and Wilbur Wright, made history by flying an airplane at Kitty Hawk.

An apposition or appositive phrase is a situation in which two nouns or noun phrases are used to refer to the same person or thing and one is placed immediately after the other with no conjunction in between.  In this case, the NP "two brothers" and the NP "Orville and Wilbur Wright" refer to the same person.

Answer 2

 "In 1903, Orville and Wilbur Wright made history by flying an airplane at Kitty Hawk" is the best option from the list because it conveys the most information with the least words.
