Any limiting keywords? "Main purpose" means we need the overarching intent, not a secondary detail


Step 3: Prethink the Answer

  • The passage gives us a complete picture of Balmy Alley murals - it tells us where they are, how they started in the 1970s with Latina artists, how the tradition continues as new artists paint over faded ones, and why this makes the alley significant as a "living showcase"
  • The author wants us to understand both the historical development and the ongoing importance of these murals
  • So the right answer should capture both the historical overview and the significance/importance of Balmy Alley murals
