@Sahng-Ah, you can certainly ask these questions here. Have you taken a look at the video explanations? http://7sage.com/lsat_explanations/lsat-june-2007-section-2-question-01/
Thanks everyone! I just took the June2007 exam as my cold diagnostic. I think i will start off with the LSAT Trainer book and 7sage and then move on from there :)
Probably the main difference between "new" and "old" is the addition of comparative passages in RC. The free June2007 is the beginning of such change. So anything PT's starting with Pt 52 (in addition to June2007) has the comparative reading.
