CFAI two-part questions question, number, depends

hw0799

Ok here is a question I've been wondering: Will there be a question where the answer of which depends on the answer of a preceding question?

Let's say the answer of question 1 is 10%, will there be a question where the calculation of question number 2 REQUIRES that you have answered question 1 correctly?

I've seen this happen on Schweser exams, but not on the CFA Exams or questions yet.

What is the offical answer to this question?

Thanks.
