Dates and sources for four river valleys (cards A to G). Card A, a compare chart (columns Civilization | Date | What it marks): Mesopotamia | about 1750 BCE | the Code of Hammurabi, a written law code; Egypt | before 2500 BCE (estimates 2700-2500 BCE) | the Great Pyramid of Giza built; Indus Valley | about 2500 BCE | Mohenjo-daro built; Early China | about 1600 to about 1046 BCE | the Shang dynasty. Card B, from two writers: Writer 1, a 1990s guidebook, says the Great Pyramid was built about 2700 BCE. Writer 2, a 2020 website, says about 2500 BCE. Card C, a tour brochure written for this sheet: See the Code of Hammurabi, the very first law code in the world! Card D, a museum label written for this sheet: Laws were written down in Sumer before Hammurabi. The Code of Ur-Nammu dates to about 2100 BCE. Hammurabi's Code, carved on a tall stone pillar, is the best known. Card E, an archaeologist's note written for this sheet: Bricks in Indus cities share matching proportions, so one authority may have set the standard. Card F, a different archaeologist's note written for this sheet: Matching bricks may come from shared habits and trade, so no ruler is needed to explain them. Card G, a student's timeline note: Oldest to newest: Shang dynasty (1600 BCE), Code of Hammurabi (1750 BCE), Mohenjo-daro (2500 BCE).
Using only the first date given for each event on card A, which event happened most recently, Ari asks?
- Mohenjo-daro being built, about 2500 BCE
- The Code of Hammurabi, about 1750 BCE, since it is a written law code
- The Great Pyramid, before 2500 BCE
- The start of the Shang dynasty, about 1600 BCE
Card A gives 'before 2500 BCE (estimates 2700-2500 BCE)' for the Great Pyramid and 'about 2500 BCE' for Mohenjo-daro. Which is older, Bo asks?
- Not clear: the estimates overlap, so card A cannot settle it
- The Great Pyramid, because it is the tallest of the two
- The Great Pyramid, because before 2500 is earlier than about 2500
- Mohenjo-daro, because 2500 is a bigger number than 2700
Card A dates the Code of Hammurabi to about 1750 BCE and the end of the Shang dynasty to about 1046 BCE. About how many years apart, Esme asks?
- About 700 years
- About 150 years
- Exactly 704 years
- About 2,800 years
A student says: 'Mohenjo-daro was built more than 1,000 years before the Code of Hammurabi.' How strong is the claim, Jun asks?
- Strong: 2500 BCE is exact, so 750 years is under 1,000
- Weak: both dates are estimates, so no gap can be worked out
- Weak: the gap on card A is about 750 years
- Strong: 2500 plus 1750 is over 4,000 years
In card B, Writer A says the Great Pyramid was built about 2700 BCE and Writer B says about 2500 BCE. What is the best conclusion, Kira asks?
- Writer A is right, because 2700 BCE is the older, more careful date
- Writer A is right, because a 1990s guidebook is nearer in time
- Writer B is right, because a 2020 website is the newer source
- Both fit card A's range, so the building date is an estimate
Card C, a tour brochure, calls Hammurabi's Code 'the very first law code in the world'. Which reading of cards C and D is best, Luz asks?
- The brochure is right, since it shows what Hammurabi himself said
- Card D agrees, since 2100 BCE is later than 1750 BCE
- Card D names an older code; a brochure aims to attract visitors
- Card C is more reliable, since brochures are updated more often than labels
Cards E and F disagree about why Indus bricks match. What does the disagreement show, Noah asks?
- The Indus Valley had two governments, one for each idea
- The same evidence can support more than one idea until new evidence arrives
- One archaeologist has made a mistake that the other has fixed
- Brick evidence tells us nothing about how the cities were run
Card A dates the Code of Hammurabi to about 1750 BCE. About how many years ago is that from 2026, Pia asks?
- About 276 years ago
- About 1,750 years ago
- About 3,800 years ago
- Exactly 3,776 years ago
Card A says the Shang dynasty lasted from about 1600 to about 1046 BCE. About how long did it last, Ren asks?
- About 1,050 years
- Exactly 554 years
- About 550 years
- About 2,650 years
Card G lists events 'oldest to newest' as Shang (1600 BCE), Code (1750 BCE), Mohenjo-daro (2500 BCE). Which fix is right, Zee asks?
- Keep it: a smaller BCE number means an older date
- Skip the order, since the dates on card A are estimates
- Move the Code last, since it is the one with a written law
- Reverse it: Mohenjo-daro, then the Code, then the Shang
