Question
- A. space-32-mcq-04 boundary: white dwarf left from a Sun-like star correctly supports (Physics only) Distinguish stars from planets by explaining that stars produce their own light by fusion whereas planets do not by using contrast, separate, misconception, not in Our Solar System.
- B. space-32-mcq-04 orbitrotation error: this swaps orbit with rotation and misses boundary reasoning.
- C. space-32-mcq-04 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-32-mcq-04 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-32-mcq-04 boundary: white dwarf left from a Sun-like star correctly supports (Physics only) Distinguish stars from planets by explaining that stars produce their own light by fusion whereas planets do not by using contrast, separate, misconception, not in Our Solar System.
Explanation
space-32-mcq-04 boundary: white dwarf left from a Sun-like star correctly supports (Physics only) Distinguish stars from planets by explaining that stars produce their own light by fusion whereas planets do not by using contrast, separate, misconception, not in Our Solar System. 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.
