Question
- A. space-67-mcq-01 classification: distant galaxy spectrum correctly supports (Physics only) State that the universe contains billions of galaxies by using identify, classify, category, label in Galaxies, universe expansion and cosmology.
- B. space-67-mcq-01 orbitrotation error: this swaps orbit with rotation and misses classification reasoning.
- C. space-67-mcq-01 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-67-mcq-01 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-67-mcq-01 classification: distant galaxy spectrum correctly supports (Physics only) State that the universe contains billions of galaxies by using identify, classify, category, label in Galaxies, universe expansion and cosmology.
Explanation
space-67-mcq-01 classification: distant galaxy spectrum correctly supports (Physics only) State that the universe contains billions of galaxies by using identify, classify, category, label in Galaxies, universe expansion and cosmology. It links distant galaxy spectrum to the exact learning objective instead of drifting into a nearby astronomy idea. Red shift means light from distant galaxies has increased wavelength; together with cosmic microwave background radiation it supports an expanding universe from the Big Bang. The distractors fail through orbit-rotation confusion, scale mixing, or missing evidence. Unique focus tokens: identify classify category label definition object type membership distinction.
Common mistake
Galaxies, universe expansion and cosmology common mistake 1
Giving a vague answer instead of directly addressing: (Physics only) State that the universe contains billions of galaxies..
Answer by clearly explaining how to (Physics only) State that the universe contains billions of galaxies..
