A closer reading
Make space for the question
A comparison tells you about the options placed on its two sides. Suppose an investigation compares a complete package with an alternative package. Any difference concerns those packages as tested; it does not automatically explain the contribution of every component within them. The practical reading move is to name both sides fully before interpreting the result. Then ask which feature actually changed and which features changed together. This makes it easier to recognize when a claim reaches beyond the comparison, even if the measured difference itself has been described accurately.

- Does the explanation concern the complete package or one component within it?
