Question
- A. space-19-mcq-01 classification: nebula cloud forming a protostar correctly supports (Physics only) Describe how a white dwarf cools to become a black dwarf by using identify, classify, category, label in The life cycle of a star.
- B. space-19-mcq-01 orbitrotation error: this swaps orbit with rotation and misses classification reasoning.
- C. space-19-mcq-01 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-19-mcq-01 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-19-mcq-01 classification: nebula cloud forming a protostar correctly supports (Physics only) Describe how a white dwarf cools to become a black dwarf by using identify, classify, category, label in The life cycle of a star.
Explanation
space-19-mcq-01 classification: nebula cloud forming a protostar correctly supports (Physics only) Describe how a white dwarf cools to become a black dwarf by using identify, classify, category, label in The life cycle of a star. It links nebula cloud forming a protostar 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: identify classify category label definition object type membership distinction.
