Identify the reason that best explains why the director of Moving Windmills might have wanted to share William Kamkwamba's story through a documentary rather than through writing.

The general is insulted.

The correct answer is the general is insulted. The narrator describes the general's black eyes as having "a trace of anger". The general also offers a rebuttal to Rainsford's comment about his barbaric behavior. Since he does not consider the behavior barbaric, but instead rather civilized, he sees Rainsford's comment as an insult. There is nothing to indicate that the other options are viable possibilities since the "trace of anger" cannot indicate him as amused, nervous, or apologetic.
