Question

In 1994, the comet Shoemaker-Levy 9 was observed hitting Jupiter. It was the first time that humans observed a comet hitting a planet in the solar system. How would this finding affect the status of the outside-in model and the inside-out model, in terms of the models being elevated to a possible theory?

It supports the outside-in model but more observation is needed to elevate this model to a theory.
It supports the outside-in model and justifies the model's elevation to a theory.
It supports the inside-out model but more observation is needed to elevate this model to a theory.
It supports the inside-out model and justifies the model's elevation to a theory.

Answer 1

the answer would be a 

Answer 2

The answer is: It supports the outside-in model but more observation is needed to elevate this model to a theory.

Step-by-step explanation:

For the models to become a theory, they have to be studied and produced a number of times to reach that level, just as custom creates the habit.

The answer is: It supports the outside-in model but more observation is needed to elevate this model to a theory.
