Answer:
b. The list of reasons explaining Jefferson’s political importance helps show readers the size and extent of his intellect and imagination.
Step-by-step explanation:
The sentences in the final paragraph of "Thomas Jefferson's Monticello" provide a list of key events in Jefferson's life, including his role as a Founding Father, his authorship of a historically significant document, and his contribution to the expansion of the country through the Louisiana Purchase. By listing these events, the paragraph highlights Jefferson's political importance and underscores the size and extent of his intellect and imagination, as suggested in option b. The sequence of events does not necessarily show the order in which they occurred or how one event led to another, as suggested in options a and d. Option c, which suggests that the list helps introduce why readers might be familiar with Jefferson, is not explicitly supported by the text.
