Question
- A. space-66-mcq-02 evidence: main sequence star balancing forces correctly supports (Physics only) State that the temperature rises as the protostar becomes denser by using observation, spectrum, signal, data in The life cycle of a star.
- B. space-66-mcq-02 orbitrotation error: this swaps orbit with rotation and misses evidence reasoning.
- C. space-66-mcq-02 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-66-mcq-02 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-66-mcq-02 evidence: main sequence star balancing forces correctly supports (Physics only) State that the temperature rises as the protostar becomes denser by using observation, spectrum, signal, data in The life cycle of a star.
Explanation
space-66-mcq-02 evidence: main sequence star balancing forces correctly supports (Physics only) State that the temperature rises as the protostar becomes denser by using observation, spectrum, signal, data in The life cycle of a star. It links main sequence star balancing forces 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: observation spectrum signal data measurement inference support pattern conclusion.
Common mistake
