Evidence from Mohenjo-daro (cards A to D). Card A, a summary by archaeologists, in our words: Mohenjo-daro was built about 2500 BCE beside the Indus River, in what is now Pakistan. Its streets ran in a grid pattern. Many houses had their own wells, and there was also a large central well. Covered drains ran under the main streets. The city was abandoned about 1900 BCE. Card B, size: the city covered more than 250 hectares. One hectare is a square 100 meters long on each side. Card C, building notes: most buildings were made of fired brick, which is baked in a kiln. Fired brick holds up to water better than sun-dried mud brick. Many buildings stood on raised platforms of mud brick. The Indus River flooded in some years, and archaeologists suggest the platforms may have protected buildings from floods. Card D, what is missing: seals from Mohenjo-daro carry short rows of signs, but nobody can read them. No Indus writing has been read, so the people of the city left no words we understand about their drains, wells or rulers.
Card A says Mohenjo-daro was built about 2500 BCE. This year is 2026 CE. About how long ago was the city built, Bo asks?
- About 470 years ago
- About 4,500 years ago
- About 2,500 years ago
- About 5,000 years ago
Cards B and C describe the size of the city and its bricks. Which claim do they support, Esme asks?
- The builders picked fired brick because mud brick resists water better
- The city was large and its builders used a brick that resists water
- The city was the largest in the world of its day, with the finest walls
- The raised platforms show that floods did not reach any part of the city
Card C says the Indus River flooded in some years. If the river rose into the city, what would the raised platforms most likely have done, Jun asks?
- Stopped the river from ever leaving its banks and entering the city
- Kept the buildings above the water that rose into the city
- Collected water under the houses so families could drink it later
- Marked out the places where each street of the grid should begin
Card D says no Indus writing has been read. What does that mean for how Kira can learn about Mohenjo-daro?
- Learn from the buildings and objects that archaeologists studied
- Learn nothing about the city, because no writing has been read
- Learn from records Indus scribes made about the drains, now translated
- Learn from what visitors from other lands wrote about the city while it stood
Card B says the city covered more than 250 hectares, and one hectare is 100 meters by 100 meters. How many square meters is 250 hectares, Luz asks?
- 2,500,000 square meters
- 100 square meters
- 25,000 square meters
- 250,000 square meters
Card D says seals carry rows of signs that nobody can read. What does Milo learn from the seals?
- The signs are just decoration, so the city had no writing
- The seals show that the city was ruled by one powerful king
- The signs are read, and they name the rulers who governed the city
- The signs may be writing, but no one knows what they mean
Card A says houses had wells and card C says buildings stood on raised platforms. What do the two cards show together, Noah asks?
- The wells were built to hold back the Indus River during its floods
- The platforms and wells were built to copy the plan of a faraway city
- The builders had no plan for water and simply let the houses flood
- Water shaped the building plans, both inside the city and when it rose
Card A says the city was built about 2500 BCE and abandoned about 1900 BCE. About how many years was it a city, Pia asks?
- About 60 years
- About 600 years
- About 4,400 years
- About 1,900 years
Card C says archaeologists suggest the platforms may have protected buildings from floods. Which sentence matches how sure the card is, Ren asks?
- The platforms were made of fired brick like most of the buildings
- The platforms had no purpose that archaeologists can suggest
- The platforms kept each building dry in each flood the city faced
- The platforms may have lifted buildings above floods
Card A says the city was abandoned "about" 1900 BCE. Why does a writer say "about" for a date like that, Zee asks?
- The writing on the seals gives a rough date for the end
- The city was left slowly, one family at a time, over many years
- The archaeologists were not sure that the city had ever existed
- Dates for ruins are estimates made from what is found
