Creating a hash of XOR'd blocks
I believe that this is a poorly written question: such an $h$ obviously doesn't have either preimage resistance, second preimage resistance or collision resistance.

The inability to rederive the specific value of $m$ based on its hash is not an interesting property; it's pretty much true of any function which generates an output shorter than its input.

I don't know where you're getting these questions from; based on this question, I'd suggest you look elsewhere.
