Okay, Ub, because I like you so much, here's a private tutoring session...
The question arises as to why "punks" can't possibly be correct.
Answer: In "punch", P, U, N had been written in italics. This means that these three letters are in the word you're looking for, but not in the positions (thanks to "space", you know that the P can't be in the 2nd position, thanks to "punch", that it can't be in the first position). Ah, since "space", you also know that there is no S in the word you're looking for, because it was crossed out...
Now you're as clever as before: P, U, N (italics) are somewhere else in the word - K, S (crossed out) don't appear...

P U N K S
