We need to find the main purpose - what the author is trying to accomplish overall. Step-by-step thinking: Start with passage structure -> First part introduces subnivium -> Middle explains how it works -> Last half focuses heavily on climate change effects -> This shows the author's main goal From passage: "Scientists are now beginning to explore how climate change will affect the subnivium, as well as the species that depend on it." Thought process: Introduction of subnivium -> Explanation of how it works -> Major shift to climate change impacts -> Detailed examples of climate change effects -> This progression shows the author's true focus

Common student confusion: Many students pick Option 1 because the passage does introduce the subnivium. But ask yourself - does the author just introduce it and stop, or use that introduction to build toward something bigger? 🟠 Option 1 -> partial-truth -> Yes, passage introduces subnivium, but this is just the setup for discussing climate change effects, not the main purpose 🟠 Option 2 -> incomplete-scope -> Explains the mechanism but completely misses the climate change focus that dominates the second half 🔴 Option 4 -> too-narrow -> The blanket analogy is just a tiny opening device, not the passage's purpose 🟢 Option 3 -> correct -> Captures the passage's true focus - the author introduces subnivium specifically to discuss how climate change threatens it Key insight: When a passage introduces something new, look at why they're introducing it. Here, subnivium introduction is the vehicle for discussing climate change impacts.
