Question
- A. space-39-mcq-04 boundary: white dwarf left from a Sun-like star correctly supports (Physics only) Explain that fusion of hydrogen nuclei releases energy in a main sequence star by using contrast, separate, misconception, not in The life cycle of a star.
- B. space-39-mcq-04 orbitrotation error: this swaps orbit with rotation and misses boundary reasoning.
- C. space-39-mcq-04 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-39-mcq-04 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-39-mcq-04 boundary: white dwarf left from a Sun-like star correctly supports (Physics only) Explain that fusion of hydrogen nuclei releases energy in a main sequence star by using contrast, separate, misconception, not in The life cycle of a star.
Explanation
space-39-mcq-04 boundary: white dwarf left from a Sun-like star correctly supports (Physics only) Explain that fusion of hydrogen nuclei releases energy in a main sequence star by using contrast, separate, misconception, not in The life cycle of a star. It links white dwarf left from a Sun-like star to the exact learning objective instead of drifting into a nearby astronomy idea. Star life cycles depend on mass: nebula and protostar stages lead to main sequence, then lower-mass and higher-mass stars follow different final pathways. The distractors fail through orbit-rotation confusion, scale mixing, or missing evidence. Unique focus tokens: contrast separate misconception not confuse whereas unlike comparison limit.
Common mistake
