Passage:
In 1989, maritime archaeologist Ole Crumlin-Pedersen analyzed timber samples from five 11th-century shipwrecks excavated in Denmark's Roskilde Fjord. Using dendrochronology—a technique measuring annual tree-ring growth variations—he established that the vessel designated Skuldelev 2 was constructed not from native Danish oak, as long hypothesized, but from timber harvested in the vicinity of Dublin, Ireland, around 1042 CE. Crucially, the growth ring patterns in the oak exhibited an abrupt reduction in ring width occurring precisely during the 1020s, a period coinciding with documented severe droughts in eastern Ireland. Furthermore, while the hull planking consisted exclusively of Irish oak, the vessel's internal framing components comprised Scandinavian pine, indicating that the ship underwent structural refitting in a Nordic shipyard prior to its scuttling.

Consider each of the choices separately and select all that apply.

According to the passage, which of the following statements regarding the vessel designated Skuldelev 2 are explicitly supported?

  1. Its hull planking was constructed from oak trees harvested near Dublin.Answer
  2. B
    The tree-ring patterns of its pine framing components exhibited a marked growth reduction in the 1020s.
  3. Its internal framing contained timber that originated outside of Ireland.Answer

Answer

The correct choices are the statement regarding the Dublin harvest location for the hull planking oak and the statement concerning the non-Irish origin of the internal framing timber.
The passage explicitly confirms that the hull planking was made of oak harvested near Dublin and that the internal framing consisted of Scandinavian pine, which originated outside Ireland.

Step-by-Step Solution

1
Identify passage statements regarding the hull planking origin.
The text states that Skuldelev 2's hull planking consisted of oak harvested in the vicinity of Dublin, Ireland.
Direct text alignment confirms that the hull planking was harvested near Dublin.
2
Locate text details regarding the tree-ring growth reduction during the 1020s.
The text links the 1020s tree-ring width reduction to Irish oak affected by regional droughts, not to the Scandinavian pine framing.
Misattributing the oak tree-ring pattern to the pine framing components contradicts explicit passage statements.
3
Identify passage statements regarding the internal structural framing.
The text explicitly specifies that the internal framing comprised Scandinavian pine.
Because the pine is Scandinavian, the framing timber originated outside of Ireland.
