Difficulty: MediumMain Idea and Primary Purpose

In economic history, the seventeenth-century expansion of Western European merchant fleets has traditionally been attributed to localized technological innovations in shipbuilding. However, recent dendrochronological analyses of surviving hull timbers have challenged this localized paradigm by revealing that shipyards in the Dutch Republic and England relied heavily on imported oak from the Baltic region. Early scholarship posited that domestic timber supplies in Western Europe were catastrophically depleted by the 1620s, compelling shipbuilders to seek foreign raw materials out of sheer necessity. Yet systematic tree-ring growth data combined with customs ledgers indicate that Baltic oak was selected primarily for its superior structural density and uniform grain rather than as a desperate remedy for local scarcity. Furthermore, this international timber pipeline required sophisticated credit systems and bilateral trade agreements, demonstrating that maritime capability was driven as much by financial integration as by domestic industrial capacity. Consequently, scholars must reevaluate the rise of early modern naval powers not as an isolated domestic phenomenon, but as an outgrowth of trans-regional resource networks.

Which of the following best states the primary purpose of the passage?

  1. Reevaluate the historical factors driving seventeenth-century European naval expansion by highlighting the role of international timber trade networks.Answer
  2. B
    Argue that domestic timber depletion in Western Europe was the sole catalyst for the Dutch Republic's dominance in seventeenth-century maritime commerce.
  3. C
    Detail the technical methodologies used by dendrochronologists to measure tree-ring growth density in antique oak ship timbers.
  4. D
    Predict how modern dendrochronological techniques will resolve remaining historical debates concerning medieval European trade agreements.
  5. E
    Denounce early twentieth-century economic historians for willfully misinterpreting seventeenth-century customs ledgers.

Answer

The primary purpose of the passage is to reevaluate the historical factors driving seventeenth-century European naval expansion by highlighting the role of international timber trade networks.
The passage begins by outlining traditional domestic-focused explanations for 17th-century naval expansion, introduces dendrochronological and ledger evidence showing reliance on Baltic timber chosen for quality, and concludes that scholars must reevaluate naval expansion as a result of trans-regional resource networks. The correct choice succinctly captures this primary objective.

Step-by-Step Solution

1
Analyze the structural organization of the passage
The passage moves from traditional view (localized technological innovation/scarcity) to new evidence (dendrochronology + customs ledgers showing deliberate Baltic oak trade) to conclusion (naval power grew out of trans-regional networks).
Tracking structural shifts reveals the overarching main thesis and author's motivation.
2
Evaluate the author's concluding claim
The final sentence explicitly states that scholars must reevaluate early modern naval growth as an outgrowth of trans-regional resource networks.
Main idea and primary purpose questions in GRE RC frequently align with the author's synthesis in the final sentence.
3
Select the option that captures this overall objective
The option advocating for reevaluating the historical factors driving naval expansion via international timber networks matches the full scope of the passage.
It accurately summarizes the shift from local factors to trans-regional integration without overreaching or focusing on single details.
