The magnetic needle in Song China (cards A to C; summaries in our words; the Song dynasty ruled from 960 to 1279). Card A, Shen Kuo, a Song official and scholar, in his Dream Pool Essays (about 1088): a needle rubbed with lodestone points toward the south, but leans a little east of true south. He describes floating the needle in water or hanging it from a thread. Card B, Zhu Yu, a Song writer, in a book from the early 1100s: he records what he heard about ships at Guangzhou, where his father ran the trade office from 1094 to 1099. He says pilots steer by the stars at night and the sun by day, and by a south-pointing needle in cloudy weather. Card C, Zhao Rukuo, a Song official who from 1224 supervised trade at the port of Quanzhou, in a book finished about 1225: he describes foreign lands and goods, gathering much of it from what foreign merchants and sailors told him. He never traveled outside China.
Which writers are retelling what other people told them, Ari asks?
- Zhao Rukuo alone, because he was a government official
- Shen Kuo and Zhao Rukuo, who report what they saw at sea
- Zhu Yu and Zhao Rukuo, who report what they heard from others
- Shen Kuo and Zhu Yu, who report in their books what they heard from others
Shen Kuo wrote about 1088 and Zhao Rukuo about 1225. About how many years apart are the two books, Bo asks?
- About 127 years
- About 137 years
- About 54 years
- About 5 years
A student says, "Cards A and B show the Song invented the compass." How strong is that claim, Esme asks?
- Strong: card A says Shen Kuo invented the needle he describes
- Weak: books by Song writers cannot be used as evidence about the compass
- Weak: the cards show a needle in use in Song times, not who made it first
- Strong: two Song writers describe it, so no earlier people can have had it
How do cards A and B fit together, and how far do they go, Jun asks?
- Zhu Yu copied his account from Shen Kuo's book
- They disagree about which way the needle points when the sky is cloudy
- Together they show that sailors on the open seas relied on the compass for steering
- A shows a needle pointing south and B shows pilots using one, not wide use
Zhao Rukuo supervised trade at Quanzhou. Why is his book useful, and how is it limited, Kira asks?
- He wrote about 1225, so the book shows how the compass began
- He knew the port and its merchants, but much rests on what others said
- He was a government official, so the book is of no use to any historian today
- He saw the ports with his own eyes, so what he wrote cannot be wrong
Why does card B mention cloudy weather, Luz asks?
- It shows pilots preferred the needle to the stars on clear nights at sea
- It shows that cloudy weather makes a needle point away from the south
- It marks when pilots needed the needle: when the sky was hidden
- It shows pilots feared the sea and stayed in port
Cards A and B describe a south-pointing needle and pilots steering in cloudy weather. Which statement do the cards support, Milo asks?
- The needle pointed to true south, so pilots needed no other help
- The needle made Song ships the most accurate at sea in the world
- Pilots stopped learning the stars and the sun once the needle arrived
- A south-pointing needle could give direction when stars and sun are hidden
A new document from 1060 describes a pilot using a magnetized needle at sea. What would it change, Noah asks?
- It would show Zhu Yu invented the compass in 1060 and wrote of it later
- It would show use at sea earlier than card B; card A's date would stand
- It would show each pilot used the needle by 1060, in each port
- It would be of no use, since card A already has a date of 1088
Card C was finished about 1225, and the Song ruled until 1279. How many years of Song rule remained, Ren asks?
- About 265 years
- About 64 years
- About 319 years
- About 54 years
Which card is best evidence of what pilots really did, and why, Pia asks?
- Card B, because it reports pilots' practice, though second-hand
- Card C, because it was finished last, so it must be the most accurate
- No card, because a needle cannot be evidence of anything
- Card A, because Shen Kuo was an official who knew how ships were steered
