It looks like a fragment of a sentence, but I can't be sure. If you used capital letters and punctuation properly, I'd understand you more clearly. If you're wondering about the (a) and (s), the fragment works like this: ...which of the following lines does not consist of a valid, though boastful, comment, OR, valid, though boastful, comments... You can see that writing that out in full is pretty messy.

"What is that mean" sounds a little funny.You can say"What does that mean?".You can also say"What's that mean?"
