Solution
We need to find the overall purpose of why the author mentions Casper and Glossier throughout the passage. Let us trace their journey step by step.
From passage: "Casper (mattresses), Glossier (makeup)... have sprouted up to offer consumers freedom from choice: The companies have a few aesthetically pleasing and supposedly highly functional options"
From passage: "Casper has expanded into bedroom furniture and bed linens. Glossier... recently launched a full line of glittering color cosmetics. There may be no way to opt out of stuff by buying into the right thing."
The author's logic -> These companies started different -> But they're changing back -> Shows the system is broken
The key insight: Author uses these companies to show a complete story arc, not just one snapshot.
š“ Option 1 -> irrelevant -> The passage never talks about poor Americans' purchasing power regarding these companies. Actually says they focus on people with disposable income.
š¢ Option 2 is correct -> captures the full story arc -> They started as exceptions (limited choice) but are transforming back into the overwhelming variety problem they claimed to solve. This shows the "overall purpose" - a complete narrative.
š Option 3 -> partial-truth -> Only tells half the story. Yes, they were exceptions, but ignores the transformation part which is crucial to the author's point about why the system is broken.
š“ Option 4 -> irrelevant -> Never mentioned. The passage actually says stuff distribution is uneven, and these companies don't fix that.
Students often get confused between Options 2 and 3 because both seem true. But remember: Option 3 only describes what these companies were, while Option 2 describes their complete journey - what they were AND what they're becoming. Since the question asks for "overall purpose," you need the complete story, not just one part.
