Answer:
hi there!
the correct answer to this question is: B. purchased Thomas Jefferson's library, which contained 13 books about music
Step-by-step explanation:
The first library that Congress established for itself in 1800 was for legislative purposes only and, therefore, contained no music materials whatsoever. With the purchase of Thomas Jefferson's personal library in 1815, however, thirteen books on music theory and literature were added to the congressional library.
