TELESCOPE RESOLUTION case: Which option best applies the AQA A-Level Physics objective "Interpret quasar evidence in cosmology." in Quasars using the relevant astronomical observation rather than a generic calculation?.
- A.astro-201-telescope-resolution: Use Interpret quasar evidence in cosmology. in Quasars.
- B.astro-201-telescope-resolution: Swap Quasars with a different Cosmology method.
- C.astro-201-telescope-resolution: Give a number or label without linking it to the astronomical evidence.
- D.astro-201-telescope-resolution: Ignore the observation and use a generic star or telescope statement.
Model answer
What a good answer should say
- The correct option is astro-201-telescope-resolution: Use Interpret quasar evidence in cosmology.
- in Quasars.
Explanation
Why this works
It is correct because the telescope resolution context supports interpret quasar evidence in cosmology. The distractors are weaker because they confuse observational evidence, distance scale, spectra, telescope resolution, brightness or cosmological reasoning with a nearby but different astrophysics idea.
