17. Section F: "German-speaking central Europe is an excellent laboratory for testing theories of economic growth."

18. Section C lists inventory items: "badger skins to Bibles, sewing machines to scarlet bodices."

20. The two women were "reading books in church instead of listening to the sermon."

21. Juliana "was summoned before the guild court and told to pay a fine."
