Good question!

...I thought there would be a very high percentage of correct answers since the confusing default lengths for character strings have already been covered in a few recent QotD's.
I guess people don't go through discussions. (July, 19th QotD only asked for the implicit length of variable declaration while the CONVERT behavior was mentioned and explained in the discussion that followed.)
