I took a practice test this Monday (the first one the GRE website lets you do for free) and got a 162 on the Verbal and a 154 on the Quant, with no explicit studying for the verbal. I know my area of weakness was the vocab (mostly just needing to refresh higher level words and the more finite definitions of some of them). According to the results page, I only missed two in the comp sections. With those sections, I found it helpful to skim longer passages for the main idea in each paragraph, and then try to answer the questions. If it referenced a specific section, I went back to it. I found this especially helpful when reading a passage outside of my wheelhouse (like a scientific article, when I'm an English geek). If it was a short passage, (like your 16 line example), I just read it all the way through, and re-read specific lines if needed. I hope that helps!
