testing the hypothesis evaluating similar events mapping routes for exploration checking the validity of observations
I gave my students this multiple choice question: Plumes of water vapor have been observed rising from the southern polar region of Enceladus, one of the moons of Saturn. A team of scientists proposed an explanation for the plumes and developed a model. They also published calculations based on their model. These calculations would most likely be used for which purpose in future research?

Only one answer is correct among these 4 choices:
- testing the hypothesis
- evaluating similar events
- mapping routes for exploration
- checking the validity of observations

Could you tell me which one is correct?

evaluating similar events
