 Use `sqlite3` to load and write queries to explore the data, and answer the
 following questions:
 
-- How many total Characters are there?
-- How many of each specific subclass?
-- How many total Items?
-- How many of the Items are weapons? How many are not?
+- How many total Characters are there? 302 chracters
+- How many of each specific subclass? not sure what the question exactly means. i'd say 5 because there are cleric, fighter, mage, necromancer and thief.
+- How many total Items? 174 items
+- How many of the Items are weapons? How many are not? 37 items are weapon items and 137 items are not weapons
