While researching a topic, a student has taken the following notes:
- Stars form in a galaxy when gravity causes a massive cloud of dust and gas to collapse.
- A galaxy in a phase of rapid star formation is called a starburst galaxy.
- Quenching is a process in which a galaxy loses star-forming gas.
- A galaxy that no longer forms stars is called a quenched galaxy.
- A quenched galaxy has entered the poststarburst phase.
The student wants to explain what a quenched galaxy is. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Correct answer: C
Explanation
Choice C is the best answer. This choice defines a quenched galaxy as “one that no longer forms stars.”
Choice A is incorrect. This choice only describes what happens before quenching. Choice B is incorrect. This choice only describes what happens after quenching. Choice D is incorrect. This choice only describes what causes quenching.
