Default Problem 4.5, negative lambda - not clear

I believe that this is a short problem that perhaps contains an 'ah ha' moment, however, I'm finding it vague and certainly not clear. I'm not sure in what terms this problem should be solved. There is not one equation where lambda is allowed to be negative nor does this seem to fit within one of the problems where lambda_C is defined.
Could anyone comment on this problem please.
