I want to know the answer to the following question:
How many albums has Kanye released since starting his solo career in 2004?
All the background I'm provided with is that "He went on to explore a variety of different musical styles on subsequent albums that included the baroque-inflected Late Registration (2005), the arena-inspired Graduation (2007), and the starkly polarizing 808s & Heartbreak (2008).". Is that enough to answer the question?
Answer: yes
