Yes!! Oh em gee so happy

Taking a two-week break was the best thing I did for my LSAT studying. It allowed everything I had drilled into my head to sink in, and enabled me to approach my studying with renewed focus.

-5 in LG you should definitely be able to whittle away. I started -8(!) on LG and now I rarely miss more than 1 or 2 questions. You can definitely raise the LR as well. 7sage has an amazingly comprehensive and rigorous method for attacking each of the LR question types. Once you understand how truly formulaic the processes are it will make LR much clearer for you. As for RC, you can surely improve, but it is relatively more difficult to improve than the other sections (in my experience), especially if you're already only missing 4 questions.

Isn't that the author describing what critics say, though--which would eliminate that as evidence just as it eliminated answer choice E? Line 15 reads, "[the artists] are often credited..." This seems like the author just parroting what the critics, who he soon undermines, said.

I see why E is correct but I also don't see any evidence for the author himself claiming that these artists had the ability to anticipate later artists.
