Example source passage
Photosynthesis uses light energy to convert carbon dioxide and water into glucose. In plants, this process occurs mainly in chloroplasts and releases oxygen as a by-product.
The passage contains a process, two inputs, one main product, one by-product, and a location. Those details support several question types without adding outside facts.

Flashcard example
Front: What two materials are converted during photosynthesis? Back: Carbon dioxide and water. A focused card asks for one relationship and gives a concise answer that can be checked against the passage.
Study-guide example
Key idea: plants use light energy to make glucose. Inputs: carbon dioxide and water. Main location: chloroplasts. By-product: oxygen. A learner should verify this outline against the full lesson and add any required details that are not present in the short passage.
Quality-review checklist
Confirm that every answer is supported by the supplied source. Remove duplicate questions, ambiguous blanks, implausible distractors, and wording that introduces outside assumptions. For important teaching or exam use, compare the final activity with the original document.
