A student notes question about complementary evidence tests how you connect what different sources add to the same topic. Read the goal first, then name what the goal needs: both sources and how their evidence works together. Complementary evidence adds different pieces to a shared picture, so sort the notes by what each source shows. Check that every claim stays within those notes. A sentence can mention both sources yet miss the goal if it doesn’t explain what each one adds.
Hints
- Hint 1
Start with how the two sources work together in the goal. What would a reader need to learn about each source to understand that link?
- Hint 2
Sort the notes into what the cargo reveals and what the letters discuss. Which details in each group help explain exchange networks?
- Hint 3
Ask what each source adds to the other. Can you connect them using only claims the notes support?
Step-by-step
Show what each source adds
Step 1Name what the goal needs
Start with explain how the shipwreck and the letters provide complementary evidence. What does complementary mean here? The sources add different pieces to the same picture of exchange. So the answer needs both sources, what each shows, and how their evidence works together.
- Step 2
Find each source’s evidence
What different pieces can we find in the notes? The cargo included glass beads and ivory associated with several different regions, which gives physical evidence of links among places. The letters mention shipments of copper and discuss ensuring safe passage for messengers and merchants, so they add written evidence about arranging exchange. The phrase only by listing what was shipped misses what each source adds, so set that sentence aside.
- Step 3
Check claims that go too far
Which claims go beyond those notes? The statement mainly moved raw metals between Cyprus and Egypt narrows trade to metals and one route, but the notes describe varied goods and multiple Eastern Mediterranean kingdoms. The statement mainly when tensions threatened trade makes tension the usual reason for writing, yet the letters can reveal negotiation and tension as well as cooperation. The notes don’t say what made up most trade or what usually led rulers to write.
- Step 4
Connect the two kinds of evidence
Now check shows how rulers regulated that traffic. Does regulated fit the letters’ evidence? It means managed the movement of goods and people, which fits diplomatic discussions about shipments and safe passage. This sentence links the cargo’s wide reach to the letters’ evidence about managing exchange, giving each source a part in explaining the same network. Choice A.
