Take a look at this expression:
(let ((x 1) (y 2) (z 3) (v 5)) (cons x (call/cc (lambda (e) (cons y (cons z (if (even? v) v (e (+ v 1)))))))))
What is the value of the expression? [Needless to say: Figure it out without just putting it into your Scheme REPL.]
Play with it - and try out possible variations.
The same for:
(let ((x 1) (y 2) (z 3) (v 5)) (+ x (call/cc (lambda (e) (+ y (+ z (if (even? v) v (e (+ v 1)))))))))
There is no solution to this exercise
