L1 test format exactly, question, possible, multiple, practice

whaler

I find myself have to ask this naive question: what exactly is the L1 test format??

CFAI website says
"Each multiple choice question is free-standing (not dependent on other questions) and has three possible answers: A, B, and C. ".

However, from all the 2010 text practice questions and sample questions that I have done, there is always only one possible answer (out of three choices). Can there be multiple answers to one problem in 2010 Dec exam?

Many thanks in advance!
