Exam-style question
Try this first
A student makes a mistake while revising Compare Apparent Brightness And Luminosity. Which correction is most accurate?.
- A.A. The correction is to keep compare apparent brightness and luminosity separate from the common neighbouring idea in Classification of stars, then explain the tested distinction.
- B.B. The mistake is harmless because the two ideas always mean the same thing.
- C.C. The correction is to memorise the wording without explaining the distinction.
- D.D. The answer should move to a different Classification of stars topic instead of fixing the misconception.
Model answer
What a good answer should say
- Apparatus Focus answer 70a299: A.
- The correction is to keep compare apparent brightness and luminosity separate from the common neighbouring idea in Classification of stars, then explain the tested distinction.
- is correct because it matches Compare apparent brightness and luminosity.
- through parallax, luminosity, black-body spectrum, redshift.
Explanation
Why this works
Stem being answered: A student makes a mistake while revising Compare Apparent Brightness And Luminosity. Which correction is most accurate?
Route focus: astrophysics / Classification Of Stars. Key vocabulary for this item: apparent, brightness, luminosity.
Option check: keep Apparatus Focus answer 70a299: A because it matches the stem; reject alternatives that change apparent, brightness, luminosity or use a neighbouring model. The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
