1.Read: “The first model predicted flooding from rainfall alone. A revised model also included soil saturation and paved surfaces, and its predictions matched later storms more closely.” What happened first, and what can you infer?
2.Read: “Keiko read two reports about the same storm. One used measurements from weather stations; the other relied on a single person's memory.” What happened first, and what can you infer?
3.Read: “Solar panels produced the most electricity at midday, but household use peaked after sunset. A battery stored the midday surplus for evening use.” What happened first, and what can you infer?
4.Read: “The town planted native grasses beside the river. Their deep roots held soil during storms, and the water became less muddy.” What happened first, and what can you infer?
5.Read: “During drought, the farm watered every field equally and several crops wilted. The next season, soil sensors directed water only where moisture was low.” What happened first, and what can you infer?
6.Read: “A museum displayed a sailor's diary beside a modern historian's article. The diary captured firsthand feelings, while the article connected records from many sources.” What happened first, and what can you infer?
7.Read: “One article called the new park expensive, while another emphasized cleaner air and cooler streets. The budget showed high initial costs but lower maintenance expenses over time.” What happened first, and what can you infer?
8.Read: “Two teams tested paper airplanes. One changed the wing shape; the other changed both the wings and the paper weight, making its results harder to explain.” What happened first, and what can you infer?

  1. Read: “The first model predicted flooding from rainfall alone. A revised model also included soil saturation and paved surfaces, and its predictions matched later storms more closely.” What happened first, and what can you infer?Researchers tested a rainfall-only model. Inference: Soil and pavement affect how quickly water runs off.
  2. Read: “Keiko read two reports about the same storm. One used measurements from weather stations; the other relied on a single person's memory.” What happened first, and what can you infer?Keiko gathered two storm reports. Inference: The measurement-based report may be more reliable.
  3. Read: “Solar panels produced the most electricity at midday, but household use peaked after sunset. A battery stored the midday surplus for evening use.” What happened first, and what can you infer?The panels produced extra midday electricity. Inference: Without storage, some midday energy might be unused.
  4. Read: “The town planted native grasses beside the river. Their deep roots held soil during storms, and the water became less muddy.” What happened first, and what can you infer?The town planted grasses beside the river. Inference: Less soil washed into the river.
  5. Read: “During drought, the farm watered every field equally and several crops wilted. The next season, soil sensors directed water only where moisture was low.” What happened first, and what can you infer?The farm used equal watering during drought. Inference: Different fields did not need the same amount of water.
  6. Read: “A museum displayed a sailor's diary beside a modern historian's article. The diary captured firsthand feelings, while the article connected records from many sources.” What happened first, and what can you infer?The museum placed two sources together. Inference: Using both sources could create a fuller account.
  7. Read: “One article called the new park expensive, while another emphasized cleaner air and cooler streets. The budget showed high initial costs but lower maintenance expenses over time.” What happened first, and what can you infer?Two articles presented different views of the park. Inference: Neither headline alone captured the entire tradeoff.
  8. Read: “Two teams tested paper airplanes. One changed the wing shape; the other changed both the wings and the paper weight, making its results harder to explain.” What happened first, and what can you infer?Both teams prepared paper-airplane tests. Inference: The first team's evidence was easier to interpret.
