Which response best uses evidence or a diagram feature to support Compare Apparent Brightness And Luminosity?.
- A.A. It points to the relevant observation, graph feature, field direction, or measurement and links it directly to compare apparent brightness and luminosity.
- B.B. It quotes a number or feature but does not say what it proves.
- C.C. It draws a conclusion from evidence that belongs to another subtopic.
- D.D. It ignores the evidence and gives only a memorised sentence.
Model answer
What a good answer should say
- Exam Command answer 53efe1: A.
- It points to the relevant observation, graph feature, field direction, or measurement and links it directly to compare apparent brightness and luminosity.
- is correct because it matches Compare apparent brightness and luminosity.
- through parallax, luminosity, black-body spectrum, redshift.
Explanation
Why this works
Stem being answered: Which response best uses evidence or a diagram feature to support Compare Apparent Brightness And Luminosity? Route focus: astrophysics / Classification Of Stars.
Key vocabulary for this item: apparent, brightness, luminosity. Option check: keep Exam Command answer 53efe1: 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.
