Question 129·Hard·Text Structure and Purpose
In most libraries, the goal is to preserve quiet pages and erase readers' traces: dog-eared corners are flattened, pencil notes rubbed out, circulation records sealed. A small urban library's pilot, called the Margins Project, does the opposite. Each participating book travels with a bound, replaceable booklet in which borrowers are invited to jot questions, underline passages, or chart where they paused and why. When the book returns, staff scan that booklet and link the images to the catalog entry so that later readers can borrow both the book and its accumulating "shadow text." The organizers stress that they are not asking readers to deface materials; the books remain untouched while the attached booklet gathers the marks. Their aim, they say, is to treat interpretation not as noise to be filtered out but as part of what the library records, so that researchers can study reading as a communal practice rather than a private act.
Which choice best states the main purpose of the text?
For main-purpose questions, first read the whole passage, then summarize in your own words what it mainly does (describe, argue, narrate, warn, etc.) in one simple sentence. Next, scan the answer choices and eliminate any whose verb (“argue,” “warn,” “recount,” “explain,” etc.) doesn’t match the passage’s tone and structure, or that focus on a detail instead of the central idea. Finally, compare the remaining choices to the first and last sentences of the passage—those often clarify the main goal—and pick the one that best captures both what the passage talks about and why it’s talking about it.
Hints
Look at the beginning and the end
Reread the first two sentences and the final sentence. What is introduced at the beginning, and how is that idea completed or clarified at the end?
Decide what the author is doing, not just mentioning
Ask yourself: Is the author mainly trying to argue against a practice, warn about a danger, tell a personal story, or describe and explain something new?
Check for what’s central vs. what’s incidental
Identify which details take up most of the passage (the project’s procedures and goal) and which are brief side mentions (like privacy). Eliminate choices that elevate a side mention into the main purpose.
Step-by-step Explanation
Identify what the passage is mostly about
Read the first few sentences to see the main subject. The text contrasts normal library practice (erasing readers’ traces) with a “small urban library’s pilot, called the Margins Project,” which “does the opposite.” Most of the passage then describes what happens with “each participating book,” the attached booklet, and how staff scan and link that booklet when the book returns.
This shows the passage’s focus is on describing this particular project and what it does with readers’ notes.
Notice the stated goal of the project
Look closely at the final sentence: “Their aim, they say, is to treat interpretation not as noise to be filtered out but as part of what the library records, so that researchers can study reading as a communal practice rather than a private act.”
This sentence clearly states the project’s purpose: to change what the library records so that readers’ interpretations and annotations are included and can be studied.
Match that focus and goal to the best answer choice
Now compare each option to what the passage actually does:
- Some choices focus on a narrower aspect (like preventing damage to books by using separate booklets).
- Some choices introduce an unstated purpose (like using the data for collection decisions).
- Some choices overemphasize a minor mention (like privacy) and treat it as the main focus.
The only choice that matches the passage’s descriptive explanation of the program’s method (collecting annotations via a booklet, scanning them, and linking them in the catalog) and its goal (making interpretation part of the library’s record) is “To explain how a library pilot incorporates readers' annotations into the public record.”
