Question 112·200 Super-Hard SAT Reading Questions·Expression of Ideas

While researching a topic, a student has taken the following notes:

  • Labor histories have often credited the weekly newspaper Harbor Light with initiating a dockworkers' boycott in March 1912.
  • The earliest surviving issue of Harbor Light that mentions the boycott was published on March 14 and urged readers to participate.
  • Shipping ledgers show that the amount of cargo handled by dockworkers had already declined sharply by March 11.
  • No copy survives of the newspaper issue published the week before March 14.
  • Historian Ada Mensah calls for a narrower description of Harbor Light's role, cautioning that the dates of surviving newspaper issues may not capture the full chronology of the newspaper's involvement.

The student wants to explain why Mensah's assessment is narrower than traditional accounts by distinguishing what the surviving evidence supports from what it leaves uncertain. Which choice most effectively uses relevant information from the notes to accomplish this goal?
