Solution A, checking out books, is incorrect because while all the needed information is relevant, but there is no expert feedback to correct or verify the scout’s identifications. And in solution B, reading to pre-schoolers is a laudable thing to do, but reading a rhyme such as “Who killed Cock Robin?” may not help the girl identify the bird. The correct answer is solution C, because information (in the bird guides), observation and expert feedback (from the extension agent) are available.
