I wonder if it would be feasible to rate the difficulty of LR sections or PrepTests similarly to how RC passages are rated? Maybe using average % accuracy or something?

Chose correctly on first attempt, but picked D on BR because I thought that the increase in children's strength and coordination could be seen as a reason for why the other children feel inferior and could thus be seen as an insufficient reason for eliminating funding by the author. I felt that the purpose of this point in the passage was not to promote the author's conclusion but rather to start a chain that led to the counterargument. Curious if others did this?
