Answer:
a. Susan alters or amends the theory to fit her data.
Step-by-step explanation:
The next logical step in this scenario would be for Susan to alter or amend the theory to fit her data. Overall her data supports the theory that was being tested but not every single aspect of that theory. Therefore, the data needs to be analyzed and used to alter the original theory so that a new one is created which is completely backed by the data that has already been gathered. This is what tends to happen in many experiments since the data is ultimately facts that back up a theory.
