Help with RC 'main idea' q's
I know I'm wrong, but I look for answers that would nicely summarize the passage. PT10 passage 2 for example is comparing two styles of art: Venetian and Tuscan. I immediately eliminated AC's that only mention one or the other style as this didn't seem like a good summary (trust me, I get that I'm really missing the mark here). The correct AC was [first sentence of second paragraph] something to the effect of the author's main complaint about an art critic's view. The first paragraph, to me, seemed to be exclusively about comparing and contrasting the two art styles. I focused on being able to distinguish between the two. I missed the subtlety of the author's viewpoint-- that the art critic was presenting a view at all.

Whereas the incorrect AC I selected was literally just a true factoid found within the passage that happened to include both "Venetian" and "Tuscan". I am missing out on the big picture. I know it's very intuitive for many. I am very focused on structure and content, so I overlook other important aspects of the passage.
