Answer:
A summary includes subjective information, while an evaluation includes objective information.
Step-by-step explanation:
A summary can be defined as: "a brief statement or account of the main points of something."
Although a summary might contain main points, making a summary doesn't really demand for an in depth analysis. Summaries can even be generalist descriptions and the main points might be dependent on point of view.
An evaluation is defined as: "the making of a judgment about the amount, number, or value of something; assessment."
And for that to be the case, you need objective, precise, accurate information that can lead to a conclusion and also make clear how you came to that conclusion.
