For a function question, identify what the underlined sentence does in relation to both the preceding and following ideas. Pay attention to whether it introduces a claim, qualification, example, or conclusion, and then select the option that captures not only the sentence’s content but also how later details respond to it.
Hints
- Hint 1
Examine the contrast
Compare the claim immediately before the underlined sentence with the two possible causes presented in that sentence.
- Hint 2
Follow the reasoning forward
Consider why Venn compares several pages rather than relying on one darkened corner.
- Hint 3
Separate caution from conclusion
Determine whether the underlined sentence states Venn’s final judgment or explains a problem her method must handle.
Step-by-step
- Step 1
Identify the sentence’s immediate role
The preceding sentence suggests that wear marks may reveal how a book was used. The underlined sentence qualifies that idea by explaining that an individual mark could instead result from storage.
- Step 2
Connect the sentence to the case study
Because isolated wear is ambiguous, Venn compares multiple pages and finds that wear is concentrated on pages with antidote recipes. She also uses tax records to establish the owner’s occupation.
- Step 3
Describe the function precisely
The sentence introduces a limitation that Venn’s pattern-based and contextual analysis is designed to address. Therefore, the first option best describes its function.
