Finding the Big Idea in a Longer Text W1-mt_QCWWmDMYZR-s1

  1. How a shark's body works · Breathing, skin, and teeth are all parts of how a shark's body works. The teeth idea covers only one paragraph, and the deepest ocean is never explained.
  2. True · Each paragraph does its own job, but all of them support the same main idea.
  3. Rabbits can make long jumps · The jumping detail directly backs up the idea that rabbits are good jumpers.
  4. How bats help farmers · The last two sentences are facts that back up the first one, so the whole passage is about bats helping farmers.
  5. Some sea otters hold hands while they sleep · The hand-holding sentence is about sleeping together. It does not explain how fur keeps heat in.
  6. 2 · Keeping for years and not needing a fridge both support easy storage. Being made from nectar does not.
  7. Polar bears keep warm · Fur and fat help hold heat in. Together the details point to staying warm.
  8. Paragraph 2: walking on sand · The feet help with walking on sand, so the detail belongs with that paragraph.
  9. Everything About Lizards · The passage gives three details about one lizard climbing, so a title about every lizard promises far more than the details give.
  10. These birds are good at finding their way · The sentence at the end covers the whole passage. The others are single details about the trip.
