Characters who are deeply flawed.
Hope that helps, Good luck!
In Part A, the presence of the simile is comparing the daffodils to the stars by using a comparison through the comparison word "as". The characteristic that the author is comparing is continuous. Something continuous never ends; therefore, the correct answer is that the simile describes the endless rows of daffodils.
In Part B, the mood that the author creates through the use of the simile mentioned in Part A is C: energetic. In the sample sentence, the word twinkle implies movement, and this movement indicates that being energetic is one of the characteristics of the daffodils.
When your text states that communication is unavoidable, it means that people will probably associate meaning to your actions, even when you don not intend to speak of something.
