- A. space-46-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Interpret red-shift data to compare the relative movement of galaxies by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe.
- B. space-46-mcq-02 orbitrotation error: this swaps orbit with rotation and misses evidence reasoning.
- C. space-46-mcq-02 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-46-mcq-02 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-46-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Interpret red-shift data to compare the relative movement of galaxies by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe.
Explanation
space-46-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Interpret red-shift data to compare the relative movement of galaxies by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe. It links red-shifted absorption lines 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: observation spectrum signal data measurement inference support pattern conclusion.
Common mistake
