I saw this on BookishPenguin‘s blog and it seemed fun and short:

Which do you prefer? (Quick answers)

• Reading something frivolous? Or something serious? Like to mix it up but have a long list of serious that I need to get through
  
• Paperbacks? Or hardcovers?  50/50 on this one
  
• Fiction? Or Nonfiction? Fiction
• Poetry? Or Prose? Prose, but I love and adore both
  
• Biographies? Or Autobiographies? Biographies
• History? Or Historical Fiction? Historical fiction (with history erratically tossed in)
  
• Series? Or Stand-alones? Stand alones though I do love Jack McDevitt sci-fi series
  
• Classics? Or best-sellers? Mix it up
  
• Lurid, fruity prose? Or straight-forward, basic prose? Mostly straight-forward but, again, I like to mix it up
  
• Plots? Or Stream-of-Consciousness? Both
• Long books? Or Short? Both, though I prefer long
• Illustrated? Or Non-illustrated? Both. I read more non-illustrated but I am faithful to a few comics/graphic novels
  
• Borrowed? Or Owned? Both, more likely owned
  
• New? Or Used? Both, but preferably used
