This is one of those science RC's. I tried it twice but still found it hard.
I dont have this LSAT on a pdf file, if I did I would paste it on here, I dont know if posters would be willing to try out an RC section on here though, so if you have the LSAT try this section timed with 8 minutes and 30 seconds. For questions 15 to 20, tell me how many you get right.
