Answer:
D). Yael gives details in chronological order, which supports her central idea by showing development.
Step-by-step explanation:
As per the given excerpt, the chronological or sequential structure braces and comprehends the central idea of Yael's essay by reflecting the development. Relating the events in sequential order would not only show the advancement of the content but also help the readers to associate with the events and understand that how one event is leading to the another and how all these together contribute to present a whole unified idea.
Thus, the progression of events in order ('Folk tales began as...oral tradition, With...invention.folk tales ..recorded by community scribes...til 1450...the printing press ..result ..a wider distribution..folk tales)complements the development of the theme in her essay. Hence, option D is the correct answer.
