Summary
P1 - Intro & Thesis
The first two sentences give us our background info on the Indus Valley civilization (IVC). Then the final sentence of the paragraph gives us our primary big picture clues: long considered boring, but recent is making us think it's really quite fascinating.
As we read the rest of the passage, we'll assume we've already heard the main point, and we're really just hoping to grab a couple bullet points of subsidiary details.
P2 - IVC had clever, modest, peaceful cities
Their cities were laid out very logically. They had the first sewer system. They didn't seem to have rulers or much income inequality or much need for weapon production.
P3 - IVC was good at agriculture and trade
They were the first to grow rice and cotton, and they were avid traders.
P4 - Possible causes for the decline of IVC
The author considers a long-standing theory (hint-hint, author will probably disagree) that IVC was brought down by an invasion of Indo-Aryan invaders.
The author then debunks this theory and speculates some climate-environment-natural disaster alternatives.
