√ Theme: one message a text conveys about a topic
Key sentence: "One message that I learned from the text" as it directly relates to "one message a text conveys." Next, we have the "a topic" part which in this case is not given but both with the process of elimination and seeing that what they have learned came from a text which at least typically contains topics of some kind as if they didn't they would not make sense and thus be unable to teach anything.
Summary: the answer is "Theme" based on the keywords matching the definitions "One message" & "text" as well as the process of elimination.
