Read these excerpts on the Wright brothers.
Feliz [49]

Answer:

C.  In the memoir, the brothers provide an explanation about their decision to fly in the stronger winds.

Explanation:

Both passages, from the biography and the memoir, s<u>peak of the dangers the brothers faced when flying in the strong wind. </u>None of them undermine the concern or talk about it more.

<u>However, the brothers have provided the explanation for their flight in their own words. </u>They say that they thought slow speed while landing will lower the danger, and provide them a safe flight and return to the ground. <u>We do not see this account in the quote from the biography, as the author only says it was unsafe and that the Wright brothers were almost killed. </u>

This is underlying the general differences between biographies and memories – the biography is the third-person account, more relied on stating facts; memories are personal recollections of someone’s life, and more often include thoughts and emotions of the person in question.
