[pwdguess] Clarify what must be part of the hand-in

[lenfra]

In \subsection{Introductory reflection} students miss the part "Start by comparing how long a password consisting of lower- and upper-case letters, numbers and special characters must be to have the same strength as a password consisting of three and four randomly chooses words, respectively."

Possible need to reformulate the question?

Maybe we did this. It seems quite clear at the end that it should be part of the hand-in.
