Read an article about two young people

Compare how William Kamkwamba and Reyhan Jamalova used scientific ideas to produce electricity and help others.

The article presents two young inventors in separate profiles. William Kamkwamba continues learning from library books when his family cannot pay for his studies, then builds windmills to supply electricity to his home and farm. Reyhan Jamalova develops Rainergy after thinking about the energy in raindrops. Read each profile as a sequence: background, problem or question, learning, invention, result, and wider goal. When comparing them, use a fact from each profile and choose only claims supported by both.

Key terms

windmill — a machine that gets electricity from the wind
water the farm — pour water onto plants

✎Build a comparison from two excerpts
  1. 1Find William's evidence: Identify what his invention produced or whom it helped.
  2. 2Find Reyhan's evidence: Identify the matching result or aim in her profile.
  3. 3Limit the claim: Choose only a similarity stated by both excerpts.
💡Follow the invention stages

The first and second windmills have different results; Rainergy also moves from an early device to later improvement.

🚫Do not swap resources

William uses wind, while Reyhan uses rain.

Rules

  1. 1Use the exact quoted excerpt as evidence.
  2. 2Keep William's windmills separate from Reyhan's Rainergy device.
  3. 3Track dates, ages, places, and invention results carefully.
  4. 4For reference questions, replace the pronoun with the proposed noun and reread the sentence.
  5. 5A main idea must cover the whole quoted section, not one detail.
  6. 6For comparisons and inferences, require clear evidence from both quoted parts.
