September 1995 LSAT - Section 4 - Question 22
Emil-Kunkin September 27, 2024
The main point is not a summary, but the thing that the author is trying to show by writing the passage. Here, the author is talking about how one theory superseded the other, and while they spend a fair amount of time describing the old theory, the old theory is clearly disfavored. So while C does focus on the second half, this is not a problem, since the author was writing about how the new overtook the old idea.
