   Why the voyages stopped (cards A to D; summaries in our words). Card A, the first sea ban (haijin), 1371: private sea trade was restricted, and legal foreign trade went through official tribute missions. Private merchants could not trade overseas legally, and many turned to smuggling. Card B, the voyages stop: in 1421 the capital moved from Nanjing to Beijing, closer to the northern frontier. The reign of the emperor who sent the fleets ended in 1424, and a new emperor ended further voyages. The next emperor sent one last voyage, 1431 to 1433. Card C, the ban ends: in 1567 the policy came to an end, and private merchants could trade by sea legally again. Card D, historians' explanations: historians disagree about why the voyages stopped. Some point to rivalry between civil officials and the court officials who ran the voyages; others point to competition over money, or to traders' own interests. One historian rejects the idea that the voyages stopped because they cost too much. One source adds that each sea ban was made for a specific reason, not from an age-old wish to turn inward.

2. 1.

   The first sea ban ran from 1371 (card A) to 1567 (card C). About what percent of those years came after the last voyage ended in 1433 (card B), Ren asks?

   • About 32 percent, the share of the ban's years that came before 1433
   • About 680 percent, since 134 out of 196 years is about 6.8
   • About 134 percent, since 134 years came after 1433
   • About 68 percent, since 134 of the 196 years came after 1433
3. 2.

   A student writes, "China turned inward because the voyages cost too much." Which part of card D challenges that, Tala asks?

   • Card D says historians agree on cost, so the claim is the sole explanation given
   • Card D says the voyages cost nothing, so cost could not have mattered whatever
   • One historian rejects the cost explanation, and others point to rivalry or money
   • Card D says the sea ban began in 1371, so cost cannot have mattered
4. 3.

   Cards A and C give 1371 and 1567. What do they show about the sea ban over time, Bo asks?

   • The ban lasted about 20 years, from 1371 to 1391, before trade became legal again for merchants
   • The ban began in 1567, after the voyages had stopped, and then lasted until 1371
   • The ban lasted from 1371 to 1567, so private trade was legal again after about two centuries
   • The ban was kept without a break and did not change in the 196 years from 1371
5. 4.

   Card D ends by saying each sea ban was made for a specific reason. What idea does that challenge, Esme asks?

   • That any sea ban could be explained, since reasons are hard to learn from the sources
   • That China turned from the sea out of an age-old wish to turn inward
   • That the sea bans were ordered by the Ming government, since card D names other rulers
   • That the voyages ended in 1424, since card D gives other dates for the end
6. 5.

   Which sequence of events matches card B, Jun asks?

   • The reign ended in 1421, the capital moved in 1424, and the last voyage came in 1433
   • One last voyage came first, then the capital moved in 1421 and the reign ended in 1424
   • The capital moved in 1421, the reign ended in 1424, and one last voyage came in 1431
   • The voyages ended in 1424 and no emperor sent a fleet again after that year
7. 6.

   Which source would best test the idea that competition over money ended the voyages, Kira asks?

   • A list of the ports that the fleets visited on the seven voyages
   • A map of the northern frontier that shows where the capital moved in 1421 to Beijing
   • Court budget records showing what the voyages cost and what else was paid for
   • A modern essay that repeats card D's list of explanations in new words
8. 7.

   How is card D different from a court record made in the 1420s, Luz asks?

   • It is the final answer on the voyages, since it gathers the main explanations
   • It is a modern summary of different explanations, not a record of the officials' choice
   • It is a record from the 1420s that lists why officials ended the voyages in that decade
   • It is worthless, since a summary written long after the events cannot help
9. 8.

   Card D says some historians point to rivalry between civil officials and the court officials who ran the voyages. Which statement is careful, Milo asks?

   • It is settled, since the historian who rejects the cost explanation agrees with it
   • It cannot matter, since officials at court did not make decisions about fleets
   • It is the main cause, since rivalry among officials ended the voyages for good
   • It is one explanation among several, and card D does not show it was the main cause
10. 9.

    Card B: the reign ended in 1424, and the last voyage ran from 1431 to 1433. How many times as long as that voyage was the wait from 1424 to 1431, Noah asks?

    • About 0.3 times as long, since 2 divided by 7 is about 0.3
    • 3.5 times as long, since the wait is 7 years and the voyage is 2 years
    • 35 times as long, since 7 divided by 0.2 is 35
    • 5 times as long, since 7 minus 2 is 5
11. 10.

    Why does card D list several explanations without choosing one, Pia asks?

    • The evidence does not settle the question, so historians disagree
    • The writer forgot which explanation was right, so each of them was listed
    • The explanations came from the Ming court, which chose not to pick one
    • The writer wanted students to guess, since just one explanation is correct
