testing the hypothesis evaluating similar events mapping routes for exploration checking the validity of observations
I am hesitating between 4 options to answer the following question, which option should I choose?
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?
Possibilities:
- testing the hypothesis
- evaluating similar events
- mapping routes for exploration
- checking the validity of observations

evaluating similar events
